Welcome to the IBM® Domino 10.0.1 Administrator Help.
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.
Setting advanced database properties
Advanced database properties include performance optimization and compression features, as well as ways to manage usability features such as unread marks and soft deletions.
The database cache
To minimize delays that occur when users, servers, or API programs open and close databases on a server, each server maintains a database cache. When a database closes and there are no users or processes using the database, Domino® puts the database in the cache so it can close it quickly. The database remains in the cache until it's opened again or for about 15 to 20 minutes, whichever comes first. Databases in the cache can be opened quickly.
Managing the database cache
You can manage the database cache using server commands and NOTES.INI settings.

Managing the database cache

You can manage the database cache using server commands and NOTES.INI settings.

About this task

You can use the server commands Dbcache Show to display databases in the cache, Dbcache Flush to close databases so that they are not open in the cache, and DBcache Disable to disable the cache (temporarily). For more information, see the related topics on these commands.

You can also use NOTES.INI settings to change the number of databases the cache holds (for example, if after monitoring you determine you should increase the number), or to change the time a database entry remains in the cache (for example, to discard entries for inactive databases).

Note: Using a NOTES.INI setting to disable the database cache, as opposed to using the server command, is not recommended.

For more information, see the Notes® and Domino® wiki articles in the related topics.
