USRC_POOLSIZE configuration parameter

The USRC_POOLSIZE configuration parameter specifies the maximum number of entries in each hash bucket of the LBAC credential memory cache. This memory cache holds information about the LBAC credentials of users.

onconfig.std value
USRC_POOLSIZE 127
values
A positive value 127 or greater that represents half of the initial maximum number of entries in the cache. The maximum value is dependent upon the shared memory configuration and available shared memory for the server instance.
takes effect
After you edit your onconfig file and restart the database server.
When you increase the value in memory by running the onmode -wm command.
When you reset the value in memory by running the onmode -wm command.

The initial number of entries in the cache is twice the value of the USRC_POOLSIZE configuration parameter. For example, if the USRC_POOLSIZE configuration parameter is set to 127, 254 entries are allowed in the cache. If all entries in a cache are full, the cache size automatically grows by 10%. To reduce the size of the cache, decrease the value of the USRC_POOLSIZE configuration parameter in the onconfig file and restart the server.
