Scripted SQL Connector

The Scripted SQL connector is an implementation of the Scripted Groovy Connector Toolkit. This connector lets you interact with any SQL database, using Groovy scripts for the ICF operations.

To use this connector, you must write a Groovy script for each operation that you want the connector to perform (create, read, update, delete, authenticate, and so on). No sample scripts are bundled with the connector, but Identity Cloud customers have access to the Scripted SQL connector source code at https://stash.forgerock.org/projects/OPENICF/repos/connectors/browse/scriptedsql-connector. This repository includes sample scripts for all the ICF operations.

Configure the Scripted SQL Connector

You cannot configure the Scripted SQL connector through the UI. Configure the connector over REST, as described in Configure Connectors Over REST.

Implemented Interfaces

This table lists the ICF interfaces that are implemented for the scripted SQL connector:

OpenICF Interfaces Implemented by the Scripted SQL Connector

The Scripted SQL Connector implements the following OpenICF interfaces. For additional details, see ICF Interfaces:

Authenticate

Provides simple authentication with two parameters, presumed to be a user name and password.

Create

Creates an object and its <literal>uid</literal>.

Delete

Deletes an object, referenced by its <literal>uid</literal>.

Resolve Username

Resolves an object by its username and returns the uid of the object.

Schema

Describes the object types, operations, and options that the connector supports.

Script on Connector

Enables an application to run a script in the context of the connector.

Any script that runs on the connector has the following characteristics:

  • The script runs in the same execution environment as the connector and has access to all the classes to which the connector has access.

  • The script has access to a connector variable that is equivalent to an initialized instance of the connector. At a minimum, the script can access the connector configuration.

  • The script has access to any script arguments passed in by the application.

Script on Resource

Runs a script on the target resource that is managed by this connector.

Search

Searches the target resource for all objects that match the specified object class and filter.

Sync

Polls the target resource for synchronization events, that is, native changes to objects on the target resource.

Test

Tests the connector configuration.

Testing a configuration checks all elements of the environment that are referred to by the configuration are available. For example, the connector might make a physical connection to a host that is specified in the configuration to verify that it exists and that the credentials that are specified in the configuration are valid.

This operation might need to connect to a resource, and, as such, might take some time. Do not invoke this operation too often, such as before every provisioning operation. The test operation is not intended to check that the connector is alive (that is, that its physical connection to the resource has not timed out).

You can invoke the test operation before a connector configuration has been validated.

Update

Updates (modifies or replaces) objects on a target resource.

== Configuration Properties
Property Type Default Encrypted(1) Required(2)

password

String

null

Yes

No

The connection password to be passed to our JDBC driver to establish a connection. Note that method DataSource.getConnection(username,password) by default will not use credentials passed into the method, but will use the ones configured here. See alternateUsernameAllowed property for more details.

customSensitiveConfiguration

GuardedString

null

Yes

No

Custom Sensitive Configuration script for Groovy ConfigSlurper

customConfiguration

String

null

No

connectionProperties

String

null

No

The connection properties that will be sent to our JDBC driver when establishing new connections. Format of the string must be [propertyName=property;]* NOTE - The "user" and "password" properties will be passed explicitly, so they do not need to be included here. The default value is null.

propagateInterruptState

boolean

false

No

Set this to true to propagate the interrupt state for a thread that has been interrupted (not clearing the interrupt state). Default value is false for backwards compatibility.

useDisposableConnectionFacade

boolean

true

No

Set this to true if you wish to put a facade on your connection so that it cannot be reused after it has been closed. This prevents a thread holding on to a reference of a connection it has already called closed on, to execute queries on it.

defaultCatalog

String

null

No

The default catalog of connections created by this pool.

validationInterval

long

3000

No

avoid excess validation, only run validation at most at this frequency - time in milliseconds. If a connection is due for validation, but has been validated previously within this interval, it will not be validated again. The default value is 30000 (30 seconds).

ignoreExceptionOnPreLoad

boolean

false

No

Flag whether ignore error of connection creation while initializing the pool. Set to true if you want to ignore error of connection creation while initializing the pool. Set to false if you want to fail the initialization of the pool by throwing exception.

jmxEnabled

boolean

true

No

Register the pool with JMX or not. The default value is true.

commitOnReturn

boolean

false

No

If autoCommit==false then the pool can complete the transaction by calling commit on the connection as it is returned to the pool If rollbackOnReturn==true then this attribute is ignored. Default value is false.

logAbandoned

boolean

false

No

Flag to log stack traces for application code which abandoned a Connection. Logging of abandoned Connections adds overhead for every Connection borrow because a stack trace has to be generated. The default value is false.

maxIdle

int

100

No

The maximum number of connections that should be kept in the pool at all times. Default value is maxActive:100 Idle connections are checked periodically (if enabled) and connections that been idle for longer than minEvictableIdleTimeMillis will be released. (also see testWhileIdle)

testWhileIdle

boolean

false

No

The indication of whether objects will be validated by the idle object evictor (if any). If an object fails to validate, it will be dropped from the pool. NOTE - for a true value to have any effect, the validationQuery parameter must be set to a non-null string. The default value is false and this property has to be set in order for the pool cleaner/test thread is to run (also see timeBetweenEvictionRunsMillis)

removeAbandoned

boolean

false

No

Flag to remove abandoned connections if they exceed the removeAbandonedTimeout. If set to true a connection is considered abandoned and eligible for removal if it has been in use longer than the removeAbandonedTimeout Setting this to true can recover db connections from applications that fail to close a connection. See also logAbandoned The default value is false.

abandonWhenPercentageFull

int

0

No

Connections that have been abandoned (timed out) wont get closed and reported up unless the number of connections in use are above the percentage defined by abandonWhenPercentageFull. The value should be between 0-100. The default value is 0, which implies that connections are eligible for closure as soon as removeAbandonedTimeout has been reached.

minIdle

int

10

No

The minimum number of established connections that should be kept in the pool at all times. The connection pool can shrink below this number if validation queries fail. Default value is derived from initialSize:10 (also see testWhileIdle)

defaultReadOnly

Boolean

null

No

The default read-only state of connections created by this pool. If not set then the setReadOnly method will not be called. (Some drivers dont support read only mode, ex: Informix)

maxWait

int

30000

No

The maximum number of milliseconds that the pool will wait (when there are no available connections) for a connection to be returned before throwing an exception. Default value is 30000 (30 seconds)

logValidationErrors

boolean

false

No

Set this to true to log errors during the validation phase to the log file. If set to true, errors will be logged as SEVERE. Default value is false for backwards compatibility.

driverClassName

String

null

No

The fully qualified Java class name of the JDBC driver to be used. The driver has to be accessible from the same classloader as tomcat-jdbc.jar

name

String

Tomcat Connection Pool[4-1538890145]

No

Returns the name of the connection pool. By default a JVM unique random name is assigned.

useStatementFacade

boolean

true

No

If a statement proxy is set, wrap statements so that equals() and hashCode() methods can be called on closed statements.

initSQL

String

null

No

A custom query to be run when a connection is first created. The default value is null.

validationQueryTimeout

int

-1

No

The timeout in seconds before a connection validation queries fail. This works by calling java.test_sample.Statement.setQueryTimeout(seconds) on the statement that executes the validationQuery. The pool itself doesnt timeout the query, it is still up to the JDBC driver to enforce query timeouts. A value less than or equal to zero will disable this feature. The default value is -1.

validationQuery

String

null

No

The SQL query that will be used to validate connections from this pool before returning them to the caller. If specified, this query does not have to return any data, it just cant throw a SQLException. The default value is null. Example values are SELECT 1(mysql), select 1 from dual(oracle), SELECT 1(MS Sql Server)

rollbackOnReturn

boolean

false

No

If autoCommit==false then the pool can terminate the transaction by calling rollback on the connection as it is returned to the pool Default value is false.

alternateUsernameAllowed

boolean

false

No

By default, the jdbc-pool will ignore the DataSource.getConnection(username,password) call, and simply return a previously pooled connection under the globally configured properties username and password, for performance reasons. The pool can however be configured to allow use of different credentials each time a connection is requested. To enable the functionality described in the DataSource.getConnection(username,password) call, simply set the property alternateUsernameAllowed to true. Should you request a connection with the credentials user1/password1 and the connection was previously connected using different user2/password2, the connection will be closed, and reopened with the requested credentials. This way, the pool size is still managed on a global level, and not on a per schema level.

dataSourceJNDI

String

null

No

The JNDI name for a data source to be looked up in JNDI and then used to establish connections to the database. See the dataSource attribute. Default value is null

validatorClassName

String

null

No

The name of a class which implements the org.apache.tomcat.jdbc.pool.Validator interface and provides a no-arg constructor (may be implicit). If specified, the class will be used to create a Validator instance which is then used instead of any validation query to validate connections. The default value is null. An example value is com.mycompany.project.SimpleValidator.

suspectTimeout

int

0

No

Timeout value in seconds. Similar to to the removeAbandonedTimeout value but instead of treating the connection as abandoned, and potentially closing the connection, this simply logs the warning if logAbandoned is set to true. If this value is equal or less than 0, no suspect checking will be performed. Suspect checking only takes place if the timeout value is larger than 0 and the connection was not abandoned or if abandon check is disabled. If a connection is suspect a WARN message gets logged and a JMX notification gets sent once.

useEquals

boolean

true

No

Set to true if you wish the ProxyConnection class to use String.equals and set to false when you wish to use == when comparing method names. This property does not apply to added interceptors as those are configured individually. The default value is true.

removeAbandonedTimeout

int

60

No

Timeout in seconds before an abandoned(in use) connection can be removed. The default value is 60 (60 seconds). The value should be set to the longest running query your applications might have.

defaultAutoCommit

Boolean

null

No

The default auto-commit state of connections created by this pool. If not set, default is JDBC driver default (If not set then the setAutoCommit method will not be called.)

testOnConnect

boolean

false

No

Validate the connection when connecting to the database for the first time. False by default. Set to true if you want to use the validationQuery as an init query.

jdbcInterceptors

String

null

No

A semicolon separated list of classnames extending org.apache.tomcat.jdbc.pool.JdbcInterceptor class. See Configuring JDBC interceptors below for more detailed description of syntaz and examples. These interceptors will be inserted as an interceptor into the chain of operations on a java.test_sample.Connection object. The default value is null.

initialSize

int

10

No

The initial number of connections that are created when the pool is started. Default value is 10

defaultTransactionIsolation

int

-1

No

The default TransactionIsolation state of connections created by this pool. One of the following: NONE, READ_COMMITTED, READ_UNCOMMITTED, REPEATABLE_READ, SERIALIZABLE If not set, the method will not be called and it defaults to the JDBC driver.

numTestsPerEvictionRun

int

0

No

Property not used in tomcat-jdbc-pool.

url

String

null

No

The URL used to connect to the database.

testOnBorrow

boolean

false

No

The indication of whether objects will be validated before being borrowed from the pool. If the object fails to validate, it will be dropped from the pool, and we will attempt to borrow another. NOTE - for a true value to have any effect, the validationQuery parameter must be set to a non-null string. In order to have a more efficient validation, see validationInterval. Default value is false

fairQueue

boolean

true

No

Set to true if you wish that calls to getConnection should be treated fairly in a true FIFO fashion. This uses the org.apache.tomcat.jdbc.pool.FairBlockingQueue implementation for the list of the idle connections. The default value is true. This flag is required when you want to use asynchronous connection retrieval. Setting this flag ensures that threads receive connections in the order they arrive. During performance tests, there is a very large difference in how locks and lock waiting is implemented. When fairQueue=true there is a decision making process based on what operating system the system is running. If the system is running on Linux (property os.name=Linux. To disable this Linux specific behavior and still use the fair queue, simply add the property org.apache.tomcat.jdbc.pool.FairBlockingQueue.ignoreOS=true to your system properties before the connection pool classes are loaded.

accessToUnderlyingConnectionAllowed

boolean

true

No

Property not used. Access can be achieved by calling unwrap on the pooled connection. see javax.test_sample.DataSource interface, or call getConnection through reflection or cast the object as javax.test_sample.PooledConnection

maxAge

long

0

No

Time in milliseconds to keep this connection. When a connection is returned to the pool, the pool will check to see if the now - time-when-connected > maxAge has been reached, and if so, it closes the connection rather than returning it to the pool. The default value is 0, which implies that connections will be left open and no age check will be done upon returning the connection to the pool.

minEvictableIdleTimeMillis

int

60000

No

The minimum amount of time an object may sit idle in the pool before it is eligible for eviction. The default value is 60000 (60 seconds).

timeBetweenEvictionRunsMillis

int

5000

No

The number of milliseconds to sleep between runs of the idle connection validation/cleaner thread. This value should not be set under 1 second. It dictates how often we check for idle, abandoned connections, and how often we validate idle connections. The default value is 5000 (5 seconds).

testOnReturn

boolean

false

No

The indication of whether objects will be validated before being returned to the pool. NOTE - for a true value to have any effect, the validationQuery parameter must be set to a non-null string. The default value is false.

useLock

boolean

false

No

Use a lock when performing operations on the connection object. False by default. Set to true if you will use a separate background thread for idle and abandon checking (e.g. JMX clients). If the pool sweeper is enabled, a lock is used, regardless of this setting.

maxActive

int

100

No

The maximum number of active connections that can be allocated from this pool at the same time. The default value is 100

username

String

null

No

The connection username to be passed to our JDBC driver to establish a connection. Note that method DataSource.getConnection(username,password) by default will not use credentials passed into the method, but will use the ones configured here. See alternateUsernameAllowed property for more details.

(1) Whether the property value is considered confidential, and is therefore encrypted in IDM.

(2) A list of operations in this column indicates that the property is required for those operations.
