    01.Not all OpenRSE errors are logged in rsecomm.log
    02.RDz host caches data structures created for MVS-related
       actions. The accumulation of these data structures can cause
       Out Of Memory errors.
    03.disconnect takes 30 min, which stalls freeing data set locks
    04.OpenRSE thread and MVSminer thread are in contention in
       writing traces onto standard.out.
    05.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)
    

Problem conclusion

  • 01.Now, the log problem is resolved
    02.RDz host now discards older data structures (using the SPIRIT
       mechanism).
    03.resolved by OpenRSE Bug 388873 - ServerUpdateHandler _senders
       list should be synchronized
    04.Now, OpenRSE is changed so that it should not write any data
       onto standard.out
    05.NPE is caused by _stdOutputHandler being null. The code has
       changed to accept a null value.
