Metric B226_EJBTimeoutRate
Monitor Template Name WLSSPI_0226
Metric Name EJB Timeout Rate
Metric Type Alarming, Reporting
WebLogic 6.0/6.1 or Both 6.1
Severity: Condition One condition: WLSSPI-0226.1: Warning, threshold 10
Description Number of times a client timed out waiting for an EJB bean (drill down).
Collection Interval 15m
Message Group WebLogic
Message Text WLSSPI-0226.1: # of times per minute a client timed out waiting for an EJB
(<$VALUE>) too high (>=<$THRESHOLD>)
Instruction Text The number of times per minute a client timed out waiting for an EJB has
exceeded the threshold value.
Probable cause: If all instances of an EJB class are active and
max-beans-in-free-pool has been reached, new clients requesting the EJB class
will be blocked until an active EJB completes a method call.
Potential impact: If the transaction times out (or, for non-transactional calls, if
five minutes elapse), WebLogic Server throws a RemoteException.
Suggested action: Verify that the max-beans-in-free-pool element has not been
set too low. Also, while WebLogic Server will always try to allocate a new bean
instance if one is not available, in reality you are limited by the number of
executable threads. In most cases, each thread will need, at most, a single bean
instance.

documentation for your WebLogic Server version available through
