CLUSTERS

Setting the maximum number of users on a server
You can also balance the workload in a cluster by using the Server_MaxUsers setting. This setting specifies the maximum number of active users allowed on a server at one time. When the server reaches this limit, the server goes into the MAXUSERS state and rejects any additional requests until the number of active users falls below the Server_MaxUsers limit. When IBM® Lotus® Domino™ rejects an access request because of a MAXUSERS state, the Cluster Manager attempts to redirect the request to another cluster server that contains the appropriate replica. If no other server is available, Domino rejects the access request and displays an explanatory message.

Note The Server_MaxUsers setting does not affect replication. Replication occurs even when a server is in a MAXUSERS state.

From the Domino Administrator

1. Click the Configuration tab.

2. In the Task pane, expand Server, and then click Configurations.

3. Do one of the following:

4. Click the NOTES.INI Settings tab.

5. Click Set/Modify Parameters.

6. In the Item field, select or enter SERVER_MAXUSERS.

7. In the Value field, enter the maximum number of users you want to access the server at the same time.

From the Web Administrator

1. Click the Configuration tab.

2. In the Task pane, expand Server, and then click Configurations.

3. Do one of the following:

4. Click the NOTES.INI Settings tab.

5. Click Set/Modify Parameters.

6. In the Available Parameters box, click SERVER_MAXUSERS, and then click Add.

7. In the Value field, enter the maximum number of users you want to access the server at the same time, and then click OK.

8. Click Save & Close.

To see how often requests are redirected, check the log file for workload balancing events or check the Cluster Manager statistics.

Note You can use the Server_MaxUsers setting with any Domino server. However, only the servers in a cluster redirect access requests to another server when a server is in a MAXUSERS state. Servers that are not in a cluster reject the access requests.
