Tuning
Use this information to improve IBM® Domino® server, Domino Web server, and messaging performance through the use of resource balancing and activity trends, Server.Load commands, advanced database properties, cluster statistics, and the Server Health Monitor.
Resource balancing and activity trends
Domino® server resource utilization can be separated into two types, system activity and user activity. System activity, which includes the level of processor, disk, memory, and network consumption that Domino generates to keep the server running, is a fixed amount of activity, as long as systems are healthy and performing smoothly. Domino servers typically use a modest percentage of their resources to run. The remaining server capacity is used to support user activity, which varies with the usefulness of the data on the server.
Balancing resources in Activity Trends to decommission a server
Decommissioning a server is a special case of workload balancing in which everything outside the default pin list is moved from the server. The databases that remain, which may still account for significant activity, are either system databases or databases that are typically installed on every server, such as templates or help files. In most cases the latter group will be the same on every server, with the possible exception of unread marks.
Pinning additional databases during resource balancing
When you set the Server Profile Options, you create a pin list of databases that cannot be moved during resource balancing. However, as part of the resource-balancing process, you can pin or unpin databases.

Pinning additional databases during resource balancing

When you set the Server Profile Options, you create a pin list of databases that cannot be moved during resource balancing. However, as part of the resource-balancing process, you can pin or unpin databases.

About this task

For example, you may want to evaluate the effect of pinning an additional database, or you may want to unpin a database to see if resources balance with fewer moves.

Pinning or unpinning databases as you balance resources does not change the saved pin list. You cannot unpin a system database or a database that is pinned by the master pin list. However, the status of each database is saved with the server profile information for the selected server profile.

Procedure

From the Domino® Administrator, click the Server - Performance tab, expand the Activity Trends section, and choose Resource Balancing.
Click the Available Databases tab.
Do one of the following:
- Select the databases that cannot be moved, and then click Pin.
- Select one or more databases that are currently pinned, and then click Unpin.
Click the Analyze button to see the effect of the new pinning information.
