    01.enhancement to remove usage of volume RESERVE
    02.When RDz server executes listds command via TSO ISPF gateway,
       the ISPF gateway creates a temporary dataset and owns it
       during the search process.
    03.Sometimes GC doesn't clean up everything and it needs more
       runs. It's useful for operator to run GC manually to confirm
       if the heap can be released by more GCs.
    04.FEK210I message says "userid cancelled" although the user was
       disconnected.
    05.2 different messages are linked to FEK100E message Id,
       one of them needs to be changed.

    07.a timeout in Lock Daemon stalls releasing a dataset lock
    08.It is possible to logon twice to the same server with the
       single.logon option activated.
    09.When RDz server performs the GetAttribute process, the
       dynamic allocation fails with reason=528.
       rsecomm.log: MVSFileSystemMiner: FFS error: severity=8,
       msgNo=2007, opcode=29, rc=4, reason=528
    10.There was no control to enable or disable text search.
    11.Long running search causes high CPU consumption
    

Problem conclusion

  • 01.enhancement to remove usage of volume RESERVE
    02.Now, RDz server skips the allocation error of the reason code
       528: already allocated to the current task .
    03.Now, a new operator command is supported to run GC:
       F rsed,APPL=DEBUG GC,PID=process_id
    04.The FEK210I message is changed to:
       {userid} was disconnected forcibly because of the active
       single.logon directive
    05.A new message Id, FEK106E, is introduced as follows:
       FEK100E Daemon port/timeout value must be digits
       FEK106E No Resource Bundle of {0}
    06.enhancement to remove usage of volume RESERVE
    07.lock.info.timeout, a new, non-customizable, property in
       rsed.envvars is providedto limit the timeout value
    08.Fix RDz server to cancel the existing connection when a new
       connection starts by the same ID.
    09.The dynamic allocation failure of the reason=528 must not be
       propagated to RDz client since usually this is not a logic
       error. It is enough for the server to log the situation.
    10.The RSE server was fixed to control text search with
       _RSE_JAVAOPTS -DDISABLE_TEXT_SEARCH in rsed.envvars.
    11.Support cancel the search at a designated time limit with
       _RSE_JAVAOPTS -Dsearch.server.limit.timeout in rsed.envvars.
