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:
