Reviewing IBM BPM caches

For performance reasons, IBM® Business Process Manager caches some information about the Process Server. The caches for IBM BPM refresh automatically and so resetting these caches should only be required when an issue exists that a reset might rectify.

Before you begin

You must log in to the Process Administrative console.

About this task

You can use the Manage Caches page in the Process Administrative console to view all caches and their status, as well as reset each cache. In addition to the name of the cache and a brief description, the Manage Caches page displays the following information for each cache on Process Server:

Table 1. Information shown on the Manage Caches page
Column heading	Explanation
Access Count	Displays the total number of times that the cache was accessed.
Cache Misses	Displays the number of times that the cache was accessed and the object to look up was not found.
Hit Rate	Displays the percentage of cache hits relative to the total access count for the cache.
Last Access	Displays the time of the most recent cache access.
Status	Shows whether the cache is on or off.
Actions	Allows you to show or reset the cache.

Procedure
