PM15261: RULE FAILS TO EXECUTE AFTER RUNTIMEEXCEPTION FOR CACHE QUERY TIM ED OUT

APAR status

• Closed as program error.

Error description

• When using PZN rule result caching and having Multiple Thread
  attempting to retrieve rule results for the same rule, it is
  possible to hit a timeout for the rule execution/retrieval.
  Should this timeout occur, alternate threads continue to wait
  and rule does not appear to reattempt execution.
  
  User would see repeated exceptions on going
  PznXMLInterpreter handleException ENTRY
  [java.lang.RuntimeException: Cache query timed out after
  60s,"Exception Thrown in PznXMLActionInterpreter.doQuery()"
  

Local fix

• invalidate cache manually through rule editor
  

Problem summary

• Experiencing an intermittent RuntimeException when executing
  Select Action rules with caching and multithread throttling
  enabled.
  
  Throttling will cause the secondary thread executing the same
  rule to wait and pull results of the initial thread execution
  from cache.  If the initial rule execution times out, all
  subsequent attempts to execute the rule will go into a wait
  state and rule execution will not be reattempted without manual
  intervention, in this case editing the rule causing the cache to
  invalidate
  

Problem conclusion

• When timeout occurs on initial thread, clean up waiting threads
  and ensure that error is properly handled allowing subsequent
  thread to retry the rule execution or fail as necessary.
  

Temporary fix
