Sun Java System Identity Synchronization for Windows 6.0 Deployment Planning Guide

Re-enabling the Directory Server Plug-Ins

To complete the failover process, the Directory Server Plug-in is re-enabled on each Directory Server, which ensures the following:

The plug-ins must be re-enabled in this order:

  1. Failover installation's preferred Directory Server.

  2. Failover installation's secondary Directory Server.

  3. All other preferred and secondary Directory Servers.

  4. All preferred and secondary Directory Server replicas.

Note –

The order in which the Directory Server Plug-ins are enabled is important. If they are enabled in the wrong order, on-demand synchronization requests could loop between two preferred Directory Servers, tying up all Directory Server connections.

When re-enabling the plug-ins, make sure to specify the configuration directory of the failover installation, for example,

This re-enabling procedure can be automated by doing more work ahead of time:

  1. Install the Directory Server Plug-ins for the failover configuration.

  2. Export the plug-ins' configuration for each master from the cn=pswsync,cn=plugins,cn=config tree.

  3. Re-enable the Directory Server Plug-ins for the primary configuration.

To fail over:

  1. Delete the cn=pswsync,cn=plugins,cn=config tree.

  2. Add the failover installation entries by using ldapmodify.

  3. Restart the directory server.
