This guide shows you how to install OpenDJ directory services. The OpenDJ project offers open source LDAP directory services in Java.

Preface

This guide shows you how to install, upgrade, and remove OpenDJ software. Unless you are planning a throwaway evaluation or test installation, read the Release Notes before you get started.

If you only want to try OpenDJ server software, and you do not plan to store any real or important data that you want to keep, then you need not read this entire guide. Instead read Procedure 1.1, "To Prepare For Installation" and Procedure 1.2, "To Install OpenDJ Directory Server With the GUI".

1. Who Should Read this Guide

This guide is written for anyone installing OpenDJ who plans to maintain directory services for client applications. Basic OpenDJ installation can be simple and straightforward, particularly if you are already acquainted with directory services. Upgrading a running directory service without a single point of failure that can cause downtime requires at least a little thought and planning. If you are doing a basic installation, you might find yourself wanting more information about the process.

This guide covers the install, upgrade, and removal (uninstall) procedures that you theoretically perform only once per version. This guide aims to provide you with an understand of what happens when you perform the steps.

You do not need to be an LDAP wizard to learn something from this guide, though knowing how to manage directory services helps. You do need to know how to manage servers and services on your operating system of choice. You can nevertheless get started with this guide, and then learn more as you go along.

2. Formatting Conventions

Most examples in the documentation are created in GNU/Linux or Mac OS X operating environments. If distinctions are necessary between operating environments, examples are labeled with the operating environment name in parentheses. To avoid repetition file system directory names are often given only in UNIX format as in /path/to/server, even if the text applies to C:\path\to\server as well.

Absolute path names usually begin with the placeholder /path/to/. This path might translate to /opt/, C:\Program Files\, or somewhere else on your system.

Command-line, terminal sessions are formatted as follows:

$echo$JAVA_HOME
/path/to/jdk

Command output is sometimes formatted for narrower, more readable output even though formatting parameters are not shown in the command.

Program listings are formatted as follows:

class Test {
public static void main(String [] args)  {
System.out.println("This is a program listing.");
}
}

3. Accessing Documentation Online

ForgeRock publishes comprehensive documentation online:

• The ForgeRock Knowledge Base offers a large and increasing number of up-to-date, practical articles that help you deploy and manage ForgeRock software.

While many articles are visible to community members, ForgeRock customers have access to much more, including advanced information for customers using ForgeRock software in a mission-critical capacity.

• ForgeRock product documentation, such as this document, aims to be technically accurate and complete with respect to the software documented. It is visible to everyone and covers all product features and examples of how to use them.

4. Using the ForgeRock.org Site

The ForgeRock.org site has links to source code for ForgeRock open source software, as well as links to the ForgeRock forums and technical blogs.

If you are a ForgeRock customer, raise a support ticket instead of using the forums. ForgeRock support professionals will get in touch to help you.

Chapter 1. Installing OpenDJ Servers

Procedure 1.1. To Prepare For Installation
1. Make sure you have a required Java environment installed as described in Section 2.1, "Java Environment" in the Release Notes.

If your default Java environment is not appropriate, set OPENDJ_JAVA_HOME to the path to the correct Java environment, or set OPENDJ_JAVA_BIN to the absolute path of the java command. The OPENDJ_JAVA_BIN environment variable is useful if you have both 32-bit and 64-bit versions of the Java environment installed, and want to make sure you use the 64-bit version.

2. Prevent antivirus and intrusion detection systems from interfering with OpenDJ directory server.

Antivirus and intrusion detection systems that do a deep inspection of database files are not compatible with OpenDJ directory server. Disable antivirus and intrusion detection systems, or at least prevent them from operating on OpenDJ directory server files.

3. Download enterprise software releases through the ForgeRock BackStage site. ForgeRock enterprise releases are thoroughly validated builds for ForgeRock customers who run OpenDJ in production deployments, and for those who want to try or test with release builds.

The following OpenDJ server software is available:

OpenDJ-3.0.0.zip, OpenDJ-OEM-3.0.0.zip (OEM Edition)

Cross-platform OpenDJ directory server installation files.

opendj_3.0.0-1_all.deb, opendj-oem_3.0.0-1_all.deb (OEM Edition)

OpenDJ directory server native package for Debian and related Linux distributions.

opendj-3.0.0-1.noarch.rpm, opendj-oem-3.0.0-1.noarch.rpm (OEM Edition)

OpenDJ directory server native package for Red Hat and related Linux distributions.

OpenDJ-3.0.0-DSML.war

Cross-platform OpenDJ DSML gateway web archive

opendj-rest2ldap-servlet-3.0.0-servlet.war

Cross-platform OpenDJ REST to LDAP gateway web archive

Note

The OEM distribution of OpenDJ directory server does not include Berkeley DB Java Edition, and so does not support JE backends.

4. If you plan to install OpenDJ DSML gateway or OpenDJ REST to LDAP gateway, make sure you have an appropriate application server installed.

For a list of supported application servers, see Section 2.4, "Application Servers" in the Release Notes.

5. If you plan to configure SSL or TLS to secure network communications between the server and client applications, get a properly signed digital certificate that your client applications recognize, such as one that fits with your organization's PKI or one provided by a recognized certificate authority.

To use the certificate during installation, the certificate must be located in a keystore provided with Java (JKS, JCEKS, PKCS#12), or on a PKCS#11 token. To import a signed certificate into a keystore, use the Java keytool command.

For details see Section 5.2, "Preparing For Secure Communications" in the Administration Guide.

Procedure 1.2. To Install OpenDJ Directory Server With the GUI

The OpenDJ setup command launches a wizard that lets you install OpenDJ directory server through a GUI.

Note

If your environment picks up an old installation of Java, installation can fail. You might see an application error due to an old Java version.

After completing the steps in Procedure 1.1, "To Prepare For Installation", follow these steps:

1. Unzip OpenDJ-3.0.0.zip, and then run the setup command, described in setup(1) in the Reference.

When you unzip OpenDJ-3.0.0.zip, a top-level opendj directory is created in the directory where you unzipped the file. On Windows systems if you unzip OpenDJ-3.0.0.zip, with Right-Click > Extract All, be sure to remove the trailing OpenDJ-3.0.0 directory from the folder you specify.

Find the setup command in the following locations:

• (UNIX|Linux) opendj/setup

• (Windows) opendj\setup.bat

2. Follow the instructions in the wizard.

The wizard presents the following screens:

• Welcome: summarizes the setup process and indicates the minimum required Java version.

• License: presents the license agreement to accept before installing OpenDJ software.

• Server Settings: prompts for basic server settings including installation path, host name, port numbers, secure connections, and credentials for the directory superuser (default bind DN: cn=Directory Manager).

• Topology Options: prompts for data replication options including whether this server is part of a replication topology, and if so, the port number and security settings for this server, as well as the connection settings for a remote replica, if available.

• Directory Data: allows you to import or to generate LDAP directory data as part of the setup process.

This screen also allows you to select the backend type for data storage.

• Runtime Options: allows you to adjust JVM settings as part of the setup process, for example, to allow OpenDJ to use more memory if necessary.

• Review: presents current selections so that you can check everything is correct before running setup, with the option to start OpenDJ directory server after setup completes.

• Finished: summarizes how setup completed, with the option to launch the OpenDJ control panel.

Figure 1.1, "OpenDJ Control Panel" shows the top-level window with status information. OpenDJ control panel manages directory data, LDAP schema, indexes, monitoring, and JVM runtime options through a GUI.

Procedure 1.3. To Start OpenDJ Control Panel

You might close OpenDJ control panel, or decide to start it later after closing the setup wizard:

• To launch OpenDJ control panel, run the control-panel command, described in control-panel(1) in the Reference.

Depending on your host system, this command is one of the following:

• (Linux|UNIX) /path/to/opendj/bin/control-panel

• (Windows) C:\path\to\opendj\bat\control-panel.bat

Procedure 1.4. To Separate OpenDJ Directory Server Tools From Data

The OpenDJ directory server setup command starts with OpenDJ tools and libraries distributed with the software, and generates the configuration files, log files, and data files required to run the server and to hold directory data. By default, all the files are co-located. Optionally, you can choose to put the data files in a different location from the tools and server libraries. After OpenDJ server tools and libraries are installed, but before the setup command is run, an instance.loc file can be used to set a different location for the configuration, logs, and data files.

Important

You cannot use a single set of server tools for multiple servers.

Tools for starting and stopping the server process, for example, work with a single configured server. They do not have a mechanism to specify an alternate server location.

If you want to set up another server after running the setup command, install another set of tools and libraries.

Follow these steps to put the configuration, logs, and data files in a different location:

1. Before running the setup command, create an instance.loc file to identify the location.

The setup command tries to read instance.loc in the same directory as the setup command, such as /path/to/opendj/.

The instance.loc file contains a single line identifying either the absolute location, such as /path/to/server, or the location relative to the instance.loc file.

2. Run the setup command to complete OpenDJ directory server installation.

The directories for the server configuration, logs, and data files are located in the directory identified in the instance.loc file.

Procedure 1.5. To Install OpenDJ Directory Server From the Command-Line

The OpenDJ setup --cli command launches a command-line installation that is interactive by default. After completing the steps in Procedure 1.1, "To Prepare For Installation", follow these steps:

1. Unzip OpenDJ-3.0.0.zip in the file system directory where you want to install the server.

The setup command, described in setup(1) in the Reference, uses the directory where you unzipped the files as the installation directory, and does not ask you where to install OpenDJ directory server. Therefore, if you want to install elsewhere on the file system, unzip the files in that location.

When you unzip OpenDJ-3.0.0.zip, a top-level opendj directory is created in the directory where you unzipped the file. On Windows systems if you unzip OpenDJ-3.0.0.zip, with Right-Click > Extract All, be sure to remove the trailing OpenDJ-3.0.0 directory from the folder you specify.

2. Run the setup --cli command found in the /path/to/opendj directory.

This command starts the setup program in interactive mode on the command-line, prompting you for each option. Alternatively, use additional setup options to specify values for the options you choose during interactive mode, thus scripting the installation process. See setup --help and the notes below.

To perform a non-interactive, silent installation, provide all the options to configure OpenDJ, and then also use the -n or --no-prompt option.

The setup command without the --cli option runs the GUI installer.

The following example shows interactive installation of OpenDJ directory server:

    $/path/to/opendj/setup --cli READ THIS SOFTWARE LICENSE AGREEMENT CAREFULLY.

Configuring Directory Server ..... Done. Importing LDIF file /path/to/Example.ldif ........... Done. Starting Directory Server ........... Done. To see basic server configuration status and configuration you can launch \ /path/to/opendj/bin/status  Notes on the options follow: Initial root user DN The root user Distinguished Name (DN) identifies a user who can perform all operations allowed for the server, called root user due to the similarity to the UNIX root user. The default, cn=Directory Manager, is a well-known name. For additional protection, use a different name. Initial root user password The root user will use simple, password-based authentication. Later you can limit cleartext access to avoid snooping, but for now use a strong password here unless this is a throwaway server. Fully qualified directory server host name OpenDJ uses fully qualified host name in self-signed certificates and for identification when you use replication. If you are installing a single server temporarily for evaluation, and are not concerned about replication and whether self-signed certificates can be trusted, then you can use an FQDN such as localhost.localdomain. Otherwise, use an FQDN that other hosts can resolve to reach your server. LDAP port The default for LDAP is 389. If you are working as a user who cannot open port 389, setup suggests 1389 by default. Administration port The default is 4444. This is the service port used to configure the server and to run tasks. Create base DNs You need a base DN, such as dc=example,dc=com, to add directory data. If you already have LDIF, the base DN you want is the DN suffix common to all entries in your LDIF. When you choose to create a base DN, the setup command also prompts you for a backend type, which identifies the implementation of the repository that holds your data. Later you can add more base DNs if your data belongs in more than one suffix. Import LDIF LDAP data interchange format (LDIF) is the standard text format for expressing LDAP data. If you have LDIF already, one reason you might not want to import the data right away is because your data uses attributes not defined in the default schema. Add schema definitions after installation, and then import from LDIF. If you have a large data set to import, also increase the import cache size, which you can do by passing a Java properties file. You might also prefer to perform data import offline. Enable SSL and TLS Enabling SSL or TLS lets you protect the network traffic between directory clients and your server: SSL SSL requires its own, separate port for LDAPS traffic. The default port for LDAPS is 636. If you are working as a user who cannot open port 636, setup suggests 1636 by default. TLS TLS lets you use StartTLS to negotiate a secure connection between a client and server, starting from the same server port you configured for LDAP. X.509 certificates The digital certificate you need for SSL and TLS can be self-signed and created while you are working. Remember that client applications view self-signed certificates like fake IDs, and so do not trust them. Self-signed certificates for externally facing ports facilitate testing, but are not intended for production use. Start the server If you do not start the server during installation, you can use the /path/to/opendj/bin/start-ds command later. 3. Run the status command, described in status(1) in the Reference, to make sure your OpenDJ server is working as expected as shown in the following example: $ /path/to/opendj/bin/status

Note

You can install OpenDJ in unattended and silent fashion, too. See the procedure, Procedure 1.8, "To Install OpenDJ Directory Server With a Properties File".

Procedure 1.6. To Install From the Debian Package

On Debian and related Linux distributions such as Ubuntu, you can install OpenDJ directory server from the Debian package:

1. (Optional) Before you install OpenDJ, install a Java runtime environment if none is installed yet:

$sudo apt-get install default-jre  2. Install the OpenDJ directory server package: $ sudo dpkg -i opendj_3.0.0-1_all.deb
Selecting previously unselected package opendj.
(Reading database ... 185569 files and directories currently installed.)
Unpacking opendj (from opendj_3.0.0-1_all.deb) ...

Setting up opendj (3.0.0) ...
Adding system startup for /etc/init.d/opendj ...
/etc/rc0.d/K20opendj -> ../init.d/opendj
/etc/rc1.d/K20opendj -> ../init.d/opendj
/etc/rc6.d/K20opendj -> ../init.d/opendj
/etc/rc2.d/S20opendj -> ../init.d/opendj
/etc/rc3.d/S20opendj -> ../init.d/opendj
/etc/rc4.d/S20opendj -> ../init.d/opendj
/etc/rc5.d/S20opendj -> ../init.d/opendj

ureadahead will be reprofiled on next reboot


The Debian package installs OpenDJ directory server in the /opt/opendj directory, generates service management scripts, adds documentation files under /usr/share/doc/opendj, and adds man pages under /opt/opendj/share/man.

The files are owned by root by default, making it easier to have OpenDJ listen on ports 389 and 636.

3. Configure OpenDJ directory server by using the command sudo /opt/opendj/setup:

$sudo /opt/opendj/setup --cli ... To see basic server configuration status and configuration you can launch /opt/opendj/bin/status  4. (Optional) Check OpenDJ directory server status: $ service opendj status
$opendj status: > Running.$ sudo /opt/opendj/bin/status

Procedure 1.7. To Install From the RPM Package

On Red Hat and related Linux distributions such as Fedora and CentOS, you can install OpenDJ directory server from the RPM package:

1. Log in as superuser to install the software:

$su Password: #  2. (Optional) Before you install OpenDJ, install a Java runtime environment if none is installed yet. You might need to download an RPM to install the Java runtime environment, and then install the RPM by using the rpm command: # rpm -ivh jre-*.rpm  3. Install the OpenDJ directory server package: # rpm -i opendj-3.0.0-1.noarch.rpm Pre Install - initial install Post Install - initial install #  The RPM package installs OpenDJ directory server in the /opt/opendj directory, generates service management scripts, and adds man pages under /opt/opendj/share/man. The files are owned by root by default, making it easier to have OpenDJ listen on ports 389 and 636. 4. Configure OpenDJ directory server by using the command /opt/opendj/setup: # /opt/opendj/setup --cli ... To see basic server configuration status and configuration you can launch /opt/opendj/bin/status  5. (Optional) Check OpenDJ directory server status: # service opendj status opendj status: > Running. # /opt/opendj/bin/status >>>> Specify OpenDJ LDAP connection parameters Administrator user bind DN [cn=Directory Manager]: Password for user 'cn=Directory Manager': --- Server Status --- Server Run Status: Started Open Connections: 1 --- Server Details --- Host Name: fedora.example.com Administrative Users: cn=Directory Manager Installation Path: /opt/opendj Version: OpenDJ 3.0.0 Java Version: version Administration Connector: Port 4444 (LDAPS) --- Connection Handlers --- Address:Port : Protocol : State -------------:------------------------:--------- -- : LDIF : Disabled 0.0.0.0:161 : SNMP : Disabled 0.0.0.0:389 : LDAP (allows StartTLS) : Enabled 0.0.0.0:636 : LDAPS : Enabled 0.0.0.0:1689 : JMX : Disabled 0.0.0.0:8080 : HTTP : Disabled --- Data Sources --- Base DN: dc=example,dc=com Backend ID: userRoot Entries: 2002 Replication:  By default OpenDJ starts in run levels 2, 3, 4, and 5: # chkconfig --list | grep opendj ... opendj 0:off 1:off 2:on 3:on 4:on 5:on 6:off  Procedure 1.8. To Install OpenDJ Directory Server With a Properties File You can install OpenDJ directory server by using the setup command with a properties file. Property names correspond to the option names, but without leading dashes. Options that take no arguments become boolean properties as in the following example: enableStartTLS=true If you use a properties file with multiple tools, prefix the property name with the tool name followed by a dot (.), in the following example: setup.rootUserPasswordFile=/tmp/pwd.txt The following steps demonstrate use of a properties file as part of a scripted installation process: 1. Prepare your properties file. This procedure uses the following example properties file: # # Sample properties file to set up OpenDJ directory server # hostname =opendj.example.com ldapPort =1389 generateSelfSignedCertificate =true enableStartTLS =true ldapsPort =1636 jmxPort =1689 adminConnectorPort =4444 rootUserDN =cn=Directory Manager rootUserPassword =password baseDN =dc=example,dc=com ldifFile =/net/install/dj/Example.ldif #sampleData =2000  If you have multiple servers to install, consider scripting creation of the properties files. 2. Prepare an installation script: $ cat /net/install/dj/1/setup.sh
#!/bin/sh

unzip -d /path/to /net/install/dj/OpenDJ-3.0.0.zip && cd /path/to/opendj
./setup --cli --propertiesFilePath /net/install/dj/1/setup.props \


The properties file contains only installation options, and does not fully configure OpenDJ directory server.

If you also want your script to configure OpenDJ directory server, follow a successful run of the setup command with dsconfig commands to configure the server. To run a series of configuration commands as a batch using the dsconfig command, use either the --batchFilePath file option, where file contains the configuration commands, or the --batch option to read from standard input as in the following example that creates a backend and sets up indexes:

/path/to/opendj/bin/dsconfig \
--port 4444 \
--hostname opendj.example.com \
--bindDN "cn=Directory Manager" \
--no-prompt \
--trustAll \
--batch <<END_OF_COMMAND_INPUT

Importing LDIF file /net/install/dj/Example.ldif ....... Done. Starting Directory Server ....... Done. To see basic server configuration status and configuration you can launch /path/to/opendj/bin/status  At this point you can use OpenDJ directory server, or you can perform additional configuration. Procedure 1.9. To Install OpenDJ REST to LDAP Gateway The OpenDJ REST to LDAP gateway functions as a web application in a web application container, running independently of OpenDJ. Alternatively, you can use the HTTP connection handler in OpenDJ directory server. For instructions see Procedure 5.7, "To Set Up REST Access to OpenDJ Directory Server" in the Administration Guide. You configure the gateway to access your directory service by editing the configuration file opendj-rest2ldap-servlet.json in the deployed OpenDJ REST to LDAP gateway web application: 1. Deploy opendj-rest2ldap-servlet-3.0.0-servlet.war according to the instructions for your application server. 2. Edit opendj-rest2ldap-servlet.json where you deployed the gateway web application. The default JSON resource for the configuration includes both connection and authentication information, and also mappings. The mappings describe how the gateway translates between JSON and LDAP representations of directory data. The default mappings are built to work with generated example data and also the sample content in Example.ldif. At minimum adjust the following gateway configuration settings: • primaryLDAPServers: Set to the correct directory server host names and port numbers • authentication: Set to the correct simple bind credentials • mappings: Make sure these match the directory data For details on the configuration see Appendix A, "REST to LDAP Configuration" in the Reference. When connecting to directory servers over LDAPS or LDAP and StartTLS, you can configure the trust manager to use a file-based truststore for server certificates that the gateway should trust. This allows the gateway to validate server certificates signed, for example, by a Certificate Authority not recognized by the Java environment when setting up LDAPS or StartTLS connections. See Section 5.2, "Preparing For Secure Communications" in the Administration Guide for an example of how to use the Java keytool command to import a server certificate into a truststore file. 3. Restart the REST to LDAP gateway or the application server to make sure the configuration changes are taken into account. 4. Make sure that your directory server is running, and then check that the gateway is connecting correctly. The following command reads Babs Jensen's entry through the gateway to a directory server holding data from Example.ldif: $ curl http://bjensen:hifalutin@opendj.example.com:8080/rest2ldap/users/bjensen

Procedure 1.10. To Install OpenDJ DSML gateway

The OpenDJ DSML gateway functions as a web application in a web application container. The DSML gateway runs independently of OpenDJ directory server. You configure the gateway to access your directory service by editing the ldap.host and ldap.port parameters in the gateway WEB-INF/web.xml configuration file:

1. Deploy OpenDJ-3.0.0-DSML.war according to the instructions for your application server.

2. Edit WEB-INF/web.xml to ensure the values for ldap.host and ldap.port are correct.

3. Restart the web application container according to the instructions for your application server.

Chapter 2. Upgrading to OpenDJ 3

This chapter covers upgrade from previous versions.

If the OpenDJ directory server version is older than 2.4.5, you must upgrade first to at least OpenDJ 2.4.5 before following the procedures in this chapter. For details on upgrading to OpenDJ 2.4.5, see Upgrading OpenDJ Directory Server.

Tip

With the migration of OpenDJ project code from Subversion to Git, the upgrade code has changed to no longer rely on Subversion revision numbers.

As a result, upgrade from a nightly build is not guaranteed to work. Upgrade from one release to another works fine, as does upgrade from a release to a nightly build.

As a workaround, rather than upgrading from a nightly build, install a new server alongside the existing server and use replication to bring the new server up to date before retiring the older server.

Procedure 2.1. Before You Upgrade
1. Prepare to perform the upgrade procedure as the user who owns the OpenDJ server files.

Make sure you have the credentials to run commands as the user who owns the server.

2. (Optional) If OpenDJ directory server runs with Java 6, move to a newer version before continuing the upgrade process.

To move to a newer version, edit the default.java-home setting in the opendj/config/java.properties file, and then run the dsjavaproperties command.

3. (Optional) If you are upgrading to OpenDJ OEM edition from OpenDJ 2.6, make sure there is enough disk space to export all of the data to LDIF files.

4. Download enterprise software releases through the ForgeRock BackStage site. ForgeRock enterprise releases are thoroughly validated builds for ForgeRock customers who run OpenDJ in production deployments, and for those who want to try or test with release builds.

5. (Optional) If you are upgrading OpenDJ directory server on Windows, and OpenDJ is registered as a Windows service, disable OpenDJ as a Windows service before upgrade, as in the following example:

C:\path\to\opendj\bat> windows-service.bat --disableService


After upgrade, you can enable OpenDJ as a Windows service again.

6. Make sure you perform a full backup of your current OpenDJ installation to revert if the upgrade fails.

Due to changes to the backup archive format, make sure you stop OpenDJ directory server and back up the file system directory where the current OpenDJ directory server is installed rather than creating a backup archive with the backup command.

Procedure 2.2. To Upgrade to OpenDJ 3

If you are upgrading to the OEM edition from OpenDJ 2.6, then this procedure does not apply. Skip instead to Procedure 2.3, "To Upgrade to OpenDJ OEM Edition".

Before starting this procedure, follow the steps in Procedure 2.1, "Before You Upgrade".

To upgrade to OpenDJ directory server installed from native packages (.deb, .rpm), use the command-line package management tools provided by the system.

Note

OpenDJ directory server backend storage options have changed since OpenDJ 2.6. The underlying implementation is based on an extensible architecture, allowing you to choose the backend storage type when you create a persistent backend for directory data.

This procedure applies when you upgrade from OpenDJ 2.6, retaining the same underlying backend storage. The configuration changes from a Local DB backend to a JE Backend, and the upgrade procedure migrates the underlying backend database. There is no need to export data to LDIF when following this procedure.

The following steps describe how to upgrade OpenDJ directory server installed from the cross-platform (.zip) delivery:

1. Log in as the user who owns the current OpenDJ server.

2. Stop the current OpenDJ server.

3. (Optional) If you have not already backed up the current OpenDJ server, make a back up copy of the directory where OpenDJ is installed.

4. Unpack the new files from the .zip delivery over the current server files.

5. Run the upgrade command, described in upgrade(1) in the Reference, to bring OpenDJ configuration and application data up to date with the new binary and script files that you copied over the current server files.

By default, the upgrade command requests confirmation before making important configuration changes. For some potentially long-duration tasks, such as rebuilding indexes, the default choice is to defer the tasks until after upgrade. Tasks that are not performed during upgrade must generally be performed after upgrade but before you restart the server.

You can use the --no-prompt option to run the command non-interactively, with the --acceptLicense option to accept the license terms non-interactively.

When using the --no-prompt option, if the upgrade command cannot complete because it requires confirmation for a potentially very long or critical task, then it exits with an error and a message about how to finish making the changes. You can add the --force option to force a non-interactive upgrade to continue in this case, also performing long running and critical tasks.

6. Start the upgraded OpenDJ server.

At this point the upgrade process is complete. See the resulting upgrade.log file for a full list of operations performed.

7. (Optional) If you are upgrading OpenDJ directory server on Windows, and you disabled OpenDJ as a Windows service in order to upgrade, enable OpenDJ as a Windows service again as in the following example:

C:\path\to\opendj\bat> windows-service.bat --enableService

Example 2.1. Upgrading to OpenDJ 3

The following example upgrades an OpenDJ 2.6.3 directory server, backing up the current server directory in case the upgrade process fails. In this example, the server properties are updated to use Java 8, and the Local DB backend is migrated to a JE backend:

$cd /path/to/$ sed -e "s/default.java-home=.*/default.java-home=\/path\/to\/jdk1.8/" \

$ Procedure 2.3. To Upgrade to OpenDJ OEM Edition If you are not upgrading to the OEM edition from OpenDJ 2.6, then this procedure does not apply. Skip instead to Procedure 2.2, "To Upgrade to OpenDJ 3". Before starting this procedure, follow the steps in Procedure 2.1, "Before You Upgrade". Note OpenDJ directory server backend storage options have changed since OpenDJ 2.6. The underlying implementation is based on an extensible architecture, allowing you to choose the backend storage type when you create a persistent backend for directory data. This procedure applies when you upgrade to the OEM edition from OpenDJ 2.6, changing the underlying backend storage. The configuration changes from a Local DB backend to a PDB Backend, but the upgrade command in this version deletes the data from OpenDJ directory server. Follow the instructions in this procedure to avoid data loss. Follow these steps: 1. Login as the user who owns the current OpenDJ server. 2. Stop the current OpenDJ server. 3. Export all of the data to LDIF files. OpenDJ directory server OEM edition uses a new backend type, PDB. This edition does not support the older Local DB backend type. The upgrade process transforms the configuration to use the new backend type, but it does not export and import directory data. You must export the data, unpack the files of the new version over the old, run the upgrade, and then import the data. The following example exports Example.com data from the userRoot backend to an LDIF file: $ export-ldif --backendID userRoot --ldifFile ../ldif/Example.ldif

4. If you have not already backed up the current OpenDJ server, make a back up copy of the directory where OpenDJ is installed.

5. Unpack the new files over the current server files:

• When upgrading the .zip distribution, overwrite the current files.

The following example overwrites the current files with the new files:

$cd /path/to ; unzip -o ~/Downloads/OpenDJ-3.0.0.zip  • When upgrading native packaging, use the command-line package management tools provided by the system to remove the 2.6 package, and then install the new package. 6. Run the upgrade command to bring OpenDJ configuration and schema data up to date with the new binary and script files that replaced existing server files. By default, the upgrade command requests confirmation before making important configuration changes. For some potentially long-duration tasks, such as rebuilding indexes, the default choice is to defer the tasks until after upgrade. Tasks that are not performed during upgrade must generally be performed after upgrade but before you restart the server. You can use the --no-prompt option to run the command non-interactively, with the --acceptLicense option to accept the license terms non-interactively. When using the --no-prompt option, if the upgrade command cannot complete because it requires confirmation for a potentially very long or critical task, then it exits with an error and a message about how to finish making the changes. You can add the --force option to force a non-interactive upgrade to continue in this case, also performing long running and critical tasks. Once this step is complete, OpenDJ directory server no longer has access to user data that was stored in Local DB backends. 7. (Optional) If user data occupies significant disk space, and not enough disk space is available, then remove binary backups of the user data that you exported to LDIF. The upgrade process moves old user backend data to opendj/db/*.bak directories. This old user backend data is not accessible after upgrade. You can remove the old user backend data as shown in the following example: $ rm -rf /path/to/opendj/db/*.bak

8. Import all of the data from LDIF files.

The following example imports Example.com data from an LDIF file to the userRoot backend:

$cd opendj/bin ; import-ldif --backendID userRoot --ldifFile ../ldif/Example.ldif  Make sure you perform this step for all user data backends. 9. Start the upgraded OpenDJ server. Replication updates the upgraded server with changes that occurred during the upgrade process. At this point the upgrade process is complete. See the resulting upgrade.log file for a full list of operations performed. Example 2.2. Upgrading To OpenDJ OEM Edition The following example upgrades an OpenDJ 2.6.3 directory server to OpenDJ OEM edition, where the backend type for data storage is PDB. With the OEM edition, Local DB and JE backends are not supported. In this example, the server properties are updated to use Java 8, and the Local DB backend configuration is converted to use PDB backend. The directory data is exported to LDIF before upgrade, and imported from LDIF after upgrade: $ cd /path/to/
$sed -e "s/default.java-home=.*/default.java-home=\/path\/to\/jdk1.8/" \ opendj/config/java.properties \ > opendj/config/java.properties.new ; \ mv opendj/config/java.properties.new opendj/config/java.properties$ /path/to/opendj/bin/dsjavaproperties

Procedure 2.4. To Upgrade Replicated Servers
• Upgrade each server sequentially, as described above.

Procedure 2.5. To Add a New Replica to an Existing Topology

Newer OpenDJ servers have updates to LDAP schema that enable support for some new features. The newer schemas are not all compatible with older servers.

When adding a new server to a replication topology with older servers and following the instructions in Section 8.3.1, "Enabling Replication" in the Administration Guide, also follow these recommendations:

1. Enable replication using the dsreplication command delivered with the new server.

2. Use the --noSchemaReplication or the --useSecondServerAsSchemaSource option to avoid copying the newer schema to the older server.

It is acceptable to copy the older schema to the newer server, though it prevents use of new features that depend on newer schema.

3. If some applications depend on Internet-Draft change numbers, see Procedure 8.17, "To Align Draft Change Numbers" in the Administration Guide.

Procedure 2.6. To Upgrade OpenDJ REST to LDAP Gateway
• Replace the gateway web application with the newer version, as for a fresh installation.

Procedure 2.7. To Upgrade OpenDJ DSML Gateway
• Replace the gateway web application with the newer version, as for a fresh installation.

Chapter 3. Removing OpenDJ Servers

Procedure 3.1. To Remove OpenDJ With the GUI Uninstaller
1. Run the uninstall command, described in uninstall(1) in the Reference.

(UNIX) Run /path/to/opendj/uninstall.

(Windows) Double-click /path/to/opendj\uninstall.bat.

(Mac OS X) Double-click /path/to/opendj/Uninstall.app.

The Uninstall Options screen appears.

2. Select the components to remove in the Uninstall Options screen, and then click Uninstall to proceed.

3. To complete the process, manually remove any remaining components indicated in the Finished screen.

Procedure 3.2. To Uninstall OpenDJ From the Command-Line
1. Login as the user who installed and runs the server.

2. Run the /path/to/opendj/uninstall --cli command.

This command starts the removal program in interactive mode on the command-line, prompting you for each option. Alternatively, use additional uninstall options to specify choices for the options. See uninstall --help for more information:

$/path/to/opendj/uninstall --cli Do you want to remove all components of the server or select the components to remove? 1) Remove all components 2) Select the components to be removed q) quit Enter choice [1]: The server is currently running and must be stopped before uninstallation can continue. Stop the Server and permanently delete the files? (yes / no) [yes]: Stopping Directory Server ..... Done. Deleting Files under the Installation Path ..... Done. The Uninstall Completed Successfully. To complete the uninstallation, you must delete manually the following files and directories: /path/to/opendj/lib See /var/....log for a detailed log of this operation.  3. If the command output tells you to delete files manually, then remove those remaining files to complete the process: $ rm -rf /path/to/opendj

Procedure 3.3. To Uninstall the Debian Package

When you uninstall the Debian package from the command-line, OpenDJ directory server is stopped if it is running:

• Remove the package from your system:

$sudo dpkg -r opendj (Reading database ... 185725 files and directories currently installed.) Removing opendj ... *Stopping OpenDJ server... Stopping Server... [03/Jun/2013:10:00:49 +0200] category=BACKEND severity=NOTICE msgID=9896306 msg=The backend userRoot is now taken offline [03/Jun/2013:10:00:49 +0200] category=CORE severity=NOTICE msgID=458955 msg=The Directory Server is now stopped *OpenDJ successfully removed$ 

Removing the package does not remove your data or configuration. You must remove /opt/opendj manually to get rid of all files.

Procedure 3.4. To Uninstall the RPM Package

When you uninstall the RPM package from the command-line, OpenDJ directory server is stopped if it is running.

• Remove the package from your system:

# rpm -e opendj
Pre Uninstall - uninstall
Stopping Server...
[03/Jun/2013:10:42:46 +0200] category=BACKEND severity=NOTICE
msgID=9896306 msg=The backend userRoot is now taken offline
[03/Jun/2013:10:42:46 +0200] category=CORE severity=NOTICE
msgID=458955 msg=The Directory Server is now stopped
Post Uninstall - uninstall
OpenDJ successfully removed.
#


Removing the package does not remove your data or configuration. You must remove /opt/opendj manually to get rid of all files.
