PI78717: IBM EXPLORER FOR Z/OS (ZEXPL) JES > RETRIEVE JOB > RS* MAY TAKE A LONG TIME AND/OR APPEAR LIKE A HANG

APAR status

• Closed as program error.

Error description

• IBM Explorer for z/OS - zExpl
  A hang may occur when you attempt to find jobs using
  JES > Retrieve Job > RS*
  
  To recreate:
  Right click on JES
  Select Retrieve Job
  Type in RS* (or something on your system that has lots of jobs)
  hit enter
  Dialog spins (unresponsive) and takes a really long time to
  complete
  
  This problem does not occur
  in the zOS Explorer v3.0.1.0.6 and prior
  

Local fix

• Disconnect the client
  

Problem summary

• A performance regression in the Retrieve Job dialog was
  unintentially introduced as part of another APAR fix.   When the
  dialog is used to do a query that yields a large set of jobs,
  for each result, a duplicate job query is triggered causing the
  dialog to appear unresponsive.
  

Problem conclusion

• An API had been introduced which changed finding a job by first
  checking a cache, then by doing a remote query.  The Retrieve
  Job function was using that API for each result that came back
  from the initial query but because those initial results were
  not yet cached, subsequent queries were triggered.  The fix for
  this is to instead use another API that only checks the cache.
  

Temporary fix
