Error description

  • IBM Rational Developer for System z - RDz - v9.5.1.1
    IBM Developer for z Systems - IDz - v14
    IBM Explorer for z/OS v3.0.1
    
    After installing the fix for APAR PI65471, the performance of
    downloading copybooks and include files is very slow and
    consumes more CPU cycles on the host.
    
    The fix for APAR PI65471 is in RDz client v9.5.1.1 iFix3
    and in the IDz client v14.0.
    
    In one example, the client makes many more RSE calls, and
    repeatedly queries (for each copybook in the open module)
    all members of each of the 8 data sets defined in the
    SYSLIB parameter of the associated property group.
    

Local fix

  • For the RDz v9.5.1 client you can rollback the client from RDz
    v9.5.1.1 iFix3
    

Problem summary

  • With the use of cached copybooks, in some cases updated
    copybooks would not be downloaded and used so a fix was
    implemented to refresh more frequently, however this caused
    performance issues.
    

Problem conclusion

  • The update is a compromise of checking for new updates and reuse
     of cached resources.
    
    
    The problem listed in this APAR has been resolved with
    IBM Rational Developer for System z V9.5.1.1 ifix4 which
    is available from the Recommended Fixes support download page:
