Error description

• APAR Error Description (unlimited lines of 64 chars):
  ***************************************************************
  IBM Rational Developer for System z - RDz - v9.5.1
  IBM Developer for z Systems - IDz - v14
  
  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
  
  If the client disconnects then
  
  
  This problem did not occur on
  RDz v9.5.1+iFix2 and prior or
  IDz v14.0.0.1 and prior
  

Local fix

• Disconnect the client
  

Problem summary

• A performance regression in the Retrieve Job dialog was
  unintentionally 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

• A API had been introduced for finding a job by first checking a
  cache, then doing a remote query when not present in the cache.
   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.
  
  The problem listed in this APAR has been resolved with
  IBM Rational Developer for z Systems V9.5.1.5 Fix Pack which
  is available from the Recommended Fixes support download page:
