Sun Microsystems 8190994 New Replication Recommendations, Manual Reset of Replication Credentials

New Replication Recommendations

2.Demote the master server to a hub, as described in “Promoting or Demoting Replicas” in Sun Java System Directory Server Enterprise Edition 6.0 Administration Guide.

3.Migrate the hub server, either using dsmig or the manual migration progress.

4.Promote the hub server to a master, as described in “Promoting or Demoting Replicas” in Sun Java System Directory Server Enterprise Edition 6.0 Administration Guide. When you promote the hub, you must assign a replicaID to the new migrated master. This new replicaID must be different to the replicaID of the old server that is being migrated, and must be unique within the replicated topology.

Manual Reset of Replication Credentials

dsmig does not migrate the password of the default replication manager entry (cn=replication manager,cn=replication,cn=config). Instead, the replication manager password is deleted. Therefore, whether you are using manual or automatic migration, you must reset the replication manager password manually.

To reset the replication manager password, use the following command:

$ dsconf set-server-prop -h host -p port def-repl-manager-pwd-file:filename

In addition, dsmig does not migrate non-default replication manager entries. If a version 5 replica uses an entry other than the default replication manager, and if this entry is under cn=config, you must add the default replication manager manually. Please refer to the documentation to add a non-default replication manager entry manually. For information about adding a non-default replication manager, see “Using a Non-Default Replication Manager” in Sun Java System Directory Server Enterprise Edition 6.0 Administration Guide.

Problems Related to Tombstone Purging

In some cases, after migrating a replicated topology you might experience problems related to tombstone purging. In some cases, tombstone entries are not purged when they should be. This problem can be resolved by re-indexing the objectclass attribute of the corresponding suffix.

New Replication Recommendations

Directory Server 6.0 does not limit the number of masters in a multi-master topology. A fully-meshed, multi-master topology with no hubs or consumers is recommended in most cases.
