Metric B224_EJBStatelessCacheUtilPct
Monitor Template Name WLSSPI_0224
Metric Name EJB Stateless Cache Utilization Percent
Metric Type Alarming, Reporting
Description Percentage of stateless EJB beans in the cache in use
WebLogic 6.0/6.1 or Both 6.1
Severity: Condition Warning: WLSSPI-0224.1, threshold 90%
Collection Interval 15m
Message Group WebLogic
Message Text WLSSPI-0224.1: % of Stateless EJBs in the cache in use (<$VALUE>%) too
high (>=<$THRESHOLD>%)
Instruction Text The utilization of the EJB cache has exceeded a threshold value.
Probable cause: The cache size may be set too low.
Potential impact: When the maximum cache size is reached, WebLogic Server
passivates (transfer from memory to secondary storage) some EJBs that have
not been recently used by a client. This could result in performance degradation.
Suggested action: Set the max-beans-in-cache attribute in the weblogic-
ejb-jar.xml file to a higher value. Tuning this value too high could consume
memory unnecessarily. For information on tuning EJB parameters, see the
'Performance and Tuning' documentation for your WebLogic Server version
available through http://e-docs.bea.com/.
