Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM WebSphere Application      *
  *                  Server using trace to debug datasources     *
  ****************************************************************
  * PROBLEM DESCRIPTION: Java cores are not generated at the     *
  *                      time of J2CA0045E messages and are      *
  *                      difficult to capture manually.          *

  ****************************************************************
  Customers are asked to generate java core when a J2CA0045E
  error occurs.  Normally this is a slowdown in the system or a
  deadlock that may be occurring at the time of the J2CA0045E
  erros.  If the problem has already resolve its self and is
  intermittent, capturing java cores after the problem does not
  help.
  The following custom connection pool properties
  ConnWaitTimeoutJavacoreInterval - time between dumps
  MaxConnWaitTimeoutJavacore - times to generate dumps, every
  time, 3 javacores with ConnWaitTimeoutJavacoreInterval interval
  will be generated.
  will automatically generate the java cores closer to the time
  of the problem.
  This APAR also introduces a trace string
  "ConnWaitTimeoutPoolContent=all", if you enable this trace
  string with above 2 properties with value larger than 0, then
  when J2CA0045E or J2CA1010E reports, it will print the pool's
  content into trace.log.
  

Problem conclusion

• Added custom connection pool properties
  ConnWaitTimeoutJavacoreInterval and MaxConnWaitTimeoutJavacore
  for J2CA0045E errors to help capture intermittent slow downs or
  dead locks that are difficult to capture when manually
  generate java cores. If enable trace string
  "ConnWaitTimeoutPoolContent=all" at same time with the 2
  properties, it will print the pool content into trace log.
  
  The fix for this APAR is targeted for inclusion in fix pack
  8.5.5.25. For more information, see 'Recommended Updates for
