    01.The RESERVE may not be released in the DELETE/RENAME
       processing when some error happens during its process.
    02.When the RDz server and client saved a large data set,
       updated records were sent to the server and then the server
       merged the updates and the data set content. But the server
       failed to merge the content when the updated data size was
       large.
    03.For some COBOL applications, debug stepping controls such
       as 'step into', 'step over' and 'step return' may stop at
       unexpected locations or may allow the application to run to
       completion.
    04.v901 introduces the USER directive to rsecomm.properties and
       documents it, but the sample rsecomm.properties file does
       not have a sample for the directive.
    05.The Config Utility step to copy sample members fails due to
       a member name mismatch. SFEKSAMP(DBGMGR) should be
       SFEKSAMP(AQEJCL) in FEK.SFEKSKEL(FEKCOPY).
    06.v90 sample SMP/E jobs underestimated the z/OS UNIX size
       growth caused by (optional) v901 PTF UI13093, and the sample
       zFS and DLIB allactions don't leave much room for growth
       after the PTF is applied. Note that the v901 media has
       updated SMP/E sample jobs.
    07.The debug miner currently terminates if zPCM is down.
    08.The debug miner goes down when debug manager returns 0 byte
       response.
    09.In TSO of z/OS 2.1, TSO Cleanup command is executed after
       the completion of the rename command, but MVS miner is not
       coded to accept the results of the Cleanup command.
    10.The debugger doesn't start because the message the
       connection manager sends to the DebugMiner for a CICS debug
       session is larger than the DebugMiner is expecting and that
       causes an exception.
    11.S0C4 in Debug Manager at getNewUserControlEntry
    12.The area is not large enough to store the log file name and
       damages some storage used by JVM.
    13.The RDz Endevor RAM is specifying "Y" in the "Move with
       history" option when invoking the CA Endevor Transfer
       Element API. This causes all versions to also be transfered
       to the target stage.
    14.Under certain conditions, the RSE keepAlive mechanism can
       fail during it's handshake such that a short read-timeout
       causes a disconnect.
    

Problem conclusion

  • 01.Now, the RESERVE is released even if some error happens in
       the DELETE/RENAME process.
    02.The RDz server and client were fixed to merge large updated
       records and the original data set properly.
    03.Debugger stepping algorithms have been updated to better
       handle nested procedures, perform blocks, paragraphs and
       program calls
    04.sample USER directive is added to
       /usr/lpp/rdz/samples/rsecomm.properties
    05.SFEKSKEL(FEKCOPY) is corrected.
    06.sample SMP/E jobs are updated
    07.The debug miner will periodically attempt connecting with
       zPCM after a failed attempt.
    08.The debug miner will periodically attempt connecting with
       debug manager after debug manager returns 0 byte response.
    09.Now, MVS miner is changed to accept the results of the
       Cleanup command.
    10.To fix the problem, the byte array used to receive messages
       from the connection manager has been made much larger, to
       accomodate the larger messages.
    11.corrected uninitialized mutex
    12.Now, the area is allocated in enough size to store the log
       file name.
    13.The RDz Endevor RAM needs to specify "N" for the "Move with
       history" option of the CA Endevor Transfer Element API.
    14.In order to avoid having a short read-timeout after a failed
       keepAlive handshake, the so timeout value gets reset. In
       addition, keepAlive on the server will accept a keepAlive
       request from the client as a tacit confirmation to it's own
       keepAlive request, ensuring the handshake does not fail.
