Last updated Apr 8, 2021

The purpose of this article is to provide assistance if you encounter a "Directory server 1 was attempting to connect to replication server 2 but has disconnected in handshake phase" error in DS/OpenDJ. You may also see a result=53 message="The Replication is configured for suffix dc=openam,dc=example,dc=org but was not able to connect to any Replication Server". This issue also affects the embedded DS/OpenDJ in AM/OpenAM.

Symptoms

The errors you will see vary slightly depending on whether DS/OpenDJ is standalone or embedded as follows: 

Standalone DS/OpenDJ

The following errors are shown in the DS/OpenDJ Errors log:

[11/Nov/2016:13:22:51 -0400] category=SYNC severity=NOTICE msgID=org.opends.messages.replication.204 msg=Replication server RS(1245) started listening for new connections on address 0.0.0.0 port 8989 [11/Nov/2016:13:22:55 -0400] category=SYNC severity=WARNING msgID=org.opends.messages.replication.208 msg=Directory server DS(8764) was unable to connect to any replication servers for domain "cn=admin data" [11/Nov/2016:13:22:59 -0400] category=SYNC severity=WARNING msgID=org.opends.messages.replication.208 msg=Directory server DS(8764) was unable to connect to any replication servers for domain "dc=example,dc=com" [11/Nov/2016:13:23:04 -0400] category=SYNC severity=WARNING msgID=org.opends.messages.replication.208 msg=Directory server DS(8764) was unable to connect to any replication servers for domain "cn=schema" [11/Nov/2016:13:23:26 -0400] category=SYNC severity=ERROR msgID=org.opends.messages.replication.178 msg=Directory server 8764 was attempting to connect to replication server 1245 but has disconnected in handshake phase [11/Nov/2016:13:43:25 -0400] MODIFY RES conn=4 op=114 msgID=115 result=53 message="The Replication is configured for suffix dc=openam,dc=example,dc=org but was not able to connect to any Replication Server" etime=1
Note

A quick trace of the log messages as demonstrated in OPENDJ-1135 (DS sometimes fail to connect to RS after server restart) points to a problem with timed out connections because the (RS) is unreachable. The logs show the RS listener is accepting local connections after they have already timed out on the client side (DS). 

Embedded DS/OpenDJ

The following error is shown in the embedded DS/OpenDJ logs:

The following error is shown in the AM/OpenAM Configuration debug log:

You will also see generic "Unwilling to Perform" errors such as the following in the AM/OpenAM Configuration log: 

amSMSEmbeddedLdap:11/16/2016 12:09:52:289 PM CDT: Thread[http-nio-0.0.0.0-9443-exec-16,5,main]: TransactionId[daaeffd3-d4a3-4324-8f1d-865e43f34773-168] ERROR: SMSEmbeddedLdapObject.modify: Error modifying entry ou=AgentUsers,ou=default,ou=OrganizationConfig,ou=1.0,ou=sunidentityrepositoryservice,ou=services,o=agentusers,ou=services,dc=openam,dc=example,dc=com by Principal: id=amadmin,ou=user,dc=openam,dc=example,dc=com, error code = Unwilling to Perform

AM/OpenAM

If you are using DS/OpenDJ with AM/OpenAM, you will encounter a variety of issues if AM/OpenAM cannot reach the DS/OpenDJ configuration store and/or user store. These issues include failures when making configuration changes, users not able to authenticate and installations failing with the following error shown in the Install log:

AMSetupServlet.processRequest: errororg.forgerock.opendj.ldap.ConnectionException: Server Connection Closed: Heartbeat failed

Recent Changes

Shut down the DS/OpenDJ replication server (RS) or the RS is down for another reason.

Restarted the RS instance.

Rebooted the VM in which DS/OpenDJ is running.

Causes

In a replicated system, the directory server (DS) must be able to connect to the RS. If the RS cannot be contacted (for example, it is down), any writes to the DS/OpenDJ server (whether they originate from DS/OpenDJ or AM/OpenAM) will fail. Restarting a server can also prevent the DS connecting to its own RS during the handshake phase. 

Solution

This issue can be resolved by upgrading to DS 5.5 and later, or OpenDJ 3.5.2; you can download this from BackStage.

Workaround

As a workaround, you can restart the RS. If you are using the embedded DS/OpenDJ in AM/OpenAM, you should restart the web application container in which AM/OpenAM runs to do this.

If the other DS/OpenDJ instance is offline for a period longer than your purge delay, you will need to initialize it from a running server once it's back online to take account of any updates that occurred while it was down, for example:

$ ./dsreplication initialize --adminUID admin --adminPassword password --baseDN dc=example,dc=com --hostSource ds1.example.com --portSource 4444 --hostDestination ds2.example.com --portDestination 4444 --trustAll --no-prompt
