CLUSTERS

Disabling cluster replication for specific databases
In a cluster, all databases are automatically set to replicate in real time so that replicas are always synchronized. However, real-time replication is needed only for databases that require constant synchronization of data. For other databases, you can disable cluster replication.

1. In the Server pane of the IBM® Lotus® Domino™ Administrator or the Web Administrator, expand All Servers or expand Clusters.

2. Choose a server in the cluster.

3. Click the Files tab.

4. In the Task pane, expand Cluster Directory.

5. Click one of the four views:


6. In the Results pane, select the databases for which you want to disable cluster replication.

7. Do one of the following:

Tip Databases with the letter "X" in the left column in the Cluster Database Directory have cluster replication disabled.

Disabling cluster replication of a database prevents only replication of changes from that database to other servers in the cluster. It does not prevent replication to the database from other cluster servers. Disabling cluster replication has no effect on standard replication.

Note To reenable cluster replication for specific databases, follow the procedure above with the following exception: In Step 7, click Tools - Enable Cluster Replication on Selected Databases from the Domino Administrator, or click Tools - Enable Replication from the Web Administrator.

Creating an agent to disable cluster replication for specific databases

As an alternate method of disabling cluster replication for specific databases, you can create an agent.

1. Open the Cluster Database Directory (CLDBDIR.NSF) on any server in the cluster.

2. Choose Create - Agent.

3. In the Name field of the Agent properties box, type a name for the agent.

4. In the Options section, choose Shared or Private, depending on who will use this agent.

5. In the Trigger field of the Runtime section, choose On event.

6. Choose "Action menu selection" as the trigger event.

7. In the Target field, choose "All selected documents."

8. Click the Security tab of the Agent properties box, and specify any security options you want.

9. Close the Agent properties box.

10. In the Programmer's pane, click Add Action.

11. In the Action field, choose Modify Field.

12. In the "Modify by" field, choose Replacing.

13. In the "The value in field" field, choose ClusterReplicate.

14. In the "With the new value" field, type 0 (zero).

15. Click Add.

16. Choose File - Save to save the agent.

Creating an agent to reenable cluster replication for specific databases

If you create an agent to disable cluster replication on specific databases, you might want to create another agent to reenable cluster replication on specific databases. To create this agent, follow the previous procedure with the following exceptions:


Running the agents

1. Open the Cluster Database Directory.

2. Select the databases for which you want to disable cluster replication or enable cluster replication.

3. Choose the appropriate agent name from the Actions menu.
