PI82859: INCORRECT VALUE OF CONNECTIONPOOLSTATS

Fixes are available

APAR status

Closed as program error.

Error description

When a connection is destroyed due to a DB connection
failure, there is a possibility that the ConnectionPoolStats
are not calculated correctly (FreeConnectionCount is not
decreased and DestroyCount is not increased) although the
actual connection
in the pool is purged.

Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server Liberty - Java 2 Connectivity (J2C)  *
****************************************************************
* PROBLEM DESCRIPTION: Some values on the ConnectionPool MBean *
*                      are not accurate when an exception is   *
*                      encountered                             *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
When using the monitor feature (monitor-1.0) in WebSphere
Application Server Liberty Profile with the ConnectionPool MBean
to monitor the connection pool, some of the values will not be
accurate in certain exception situations.  When there is an
exception while destroying a connection, the
ManagedConnectionCount and FreeConnectionCount will not be
decremented correctly and the DestroyCount will not be
incremented correctly.  When there is an exception encountered
while waiting for a connection, the time spent waiting for that
connection will not be correctly added to the average InUseTime
value.

Problem conclusion

The code was changed so that the values for the ConnectionPool
MBean are accurate in the exception situations described.

The fix for this APAR is currently targeted for inclusion in fix
pack 17.0.0.3.  Please refer to the Recommended Updates page for
