Lotus Domino Administrator 8 Help - Managing the memory cache on the Web server

WEB SERVERS

Managing the memory cache on the Web server
Mapping information about databases and authenticating users can take time. To optimize response time, IBM® Lotus® Domino™ uses a memory cache (command cache) to store this information. The memory cache stores the information for quick access.

To monitor the effectiveness of the memory cache settings, look at the Domino.Cache statistics. See Tools for monitoring the Domino server.

To manage memory cache on a Web server

1. Open the Server document you want to edit and click Edit Server.

2. Choose Internet Protocols - Domino Web Engine. Under Memory Caches, complete these fields:

Field Action

Maximum cached designs Enter the number of database design elements to cache for users. The default is 128.
When a user opens a database, Domino maps each design element name to an identification number. This mapping procedure takes time. Use this field to specify how many elements you want to store in memory so the next time a user accesses that element, it is immediately available.

Maximum cached users Enter the number of users to cache. The default is 64.
After a user successfully authenticates with a server, Domino stores in memory the user's name, password, and the list of groups to which the user belongs. Use this field to increase the number of users for whom Domino stores this information.

Cached user expiration interval Enter the time interval in seconds during which Domino regularly removes user names, passwords, and group memberships from the cache. The default is 120.
Remove user names, passwords, and group memberships from the cache periodically to force Domino to look up credentials in the directory the next time those users access the server.
