Error description

  • Rational Developer for System z - RDz - v8.0.3.
    Client used Windows taskmanager to end the RDz client because
    a Edit/save operation of a pds-member did not finish.
    
    The lock on the host for this member was not released.
    After a new connect of the client the lock had to be released
    by terminating the rDz threadpool that held the lock.
    
    This problem can also occur if a user keeps the RDz client
    logged onto the host overnight, and during the night the
    workstation is restarted because of automatic installations.
    The next day the user may still have a lock on the user's
    Source PDS-Library.
    ***************************************************************
    Local fix:
    To release the lock the applicable RDz threadpool has to be
    terminated.

    ****************************************************************
    01.data set lock not released when client ends due to NPE in
       finish processing java.lang.NullPointerException at org.
       eclipse.rse.internal.dstore.universal.miners.command.
       CommandMinerThread.sendExit(CommandMinerThread.java:1066)
       followed later by
       java.lang.NullPointerException at org.eclipse.rse.internal.
       dstore.universal.miners.command.CommandMinerThread.
       cleanupThread(CommandMinerThread.java:1114)
    02.creation of a backup file causes a problem when editing a
       file in a read-only folder (not allowed to create a new file)
    03.OpenRSE thread and MVSminer thread are in contention in
       writing traces onto standard.out.
    

Problem conclusion

  • 01.NPE is caused by _stdOutputHandler being null. The code has
       changed to accept a null value.
    02.v8033 PTF UK81498 altered the way backups were created. The
       problem that was introduced is now resolved.
       problem bypass: add the following to rsed.envvars to disable
       the creation of the backup file
       _RSE_JAVAOPTS="$_RSE_JAVAOPTS -Dbackupfiles=false"
    03.Now, OpenRSE is changed so that it should not write any data
       onto standard.out
