  01.Some searches consumed too much CPU because the search
     couldn't stop until the number of matched results reached to
     the number the client specified or all data sets user
     selected were searched.
  02.FEK210I message says "userid cancelled" although the user
     was disconnected.
  03.In RDz Daemon, logon sometimes took so long that the client
     timed out and closed the socket. This lead to the Broken
     pipe messge encountered by the RDz daemon.
  04.TCP/IP connection between RDz Daemon and IVP program is not
     closed. The RDz daemon just invoke C close API to close the
     TCP/IP session, but it's not enough to close the session.
  05.2 different messages are linked to FEK100E message Id, one
     of them needs to be changed.
  06.ThreadPool server will activate ZosSystemMiner but this
     action may break the synchronization between Open RSE client
     and server programs.
  07.In PM80961, all of the zOS RESERVE invocations are removed.
  08.RDz "RDL 1" & "RSL 1" commands result in FEK202E Invalid
     Command entered.
  09.When APPLID is specified in rsed.envvras, the APPLID is not
     set correctly when creating a new thread.
  10.enhancement to remove usage of volume RESERVE
  11.When RDz server performs the GetAttribute process, the
     dynamic allocation failed owing to reason=528.
  12.There was no control to enable or disable text search.
  13.Long running search causes high CPU consumption
  

Problem conclusion

• 01.The RDz server was fixed to support limitations for the
     searched number of matches, lines, and files, and the server
     and client were fixed to stop the search when the search
     reached to the limitations.
  02.The FEK210I message is changed to: {userid} was disconnected
     forcibly due to the active single.logon directive
  03.Now, RDz Daemon monitors the client connection and if
     closed, RDz will not send any data to the client.
  04.Now RDz daemon will invoke C shutdown API before invoking
     the close API.
  05.A new message Id, FEK106E, is introduced as follows: FEK106E
     No Resource Bundle of consolemessage.properties
  06.Now, ZosSystemMiner will be activated not by
     ThreadPoolServer but by RDz client command.
  07.The zOS RESERVE invocations are recovered and the RESERVE
     invocation have RET=USE parameter so that the thread could
     not wait for the control of the data set infinitely. The
     maximum time to retry the invocation of the RESERVE API can
     be defined in "ffs.retry.time" property in rsed.envvars. The
     "ffs.retry.time" value is defined in seconds.
  08.Now,RDz "RDL 1" & "RSL 1" commands works normally
  09.Now, APPLID is set correctly in creating a thread whether or
     not the APPLID is specified in rsed.envvars.
  10.enhancement to remove usage of volume RESERVE
  11.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.
  12.The RSE server was fixed to control text search with
     _RSE_JAVAOPTS -DDISABLE_TEXT_SEARCH in rsed.envvars.
  13.Support cancel the search at a designated time limit with
     _RSE_JAVAOPTS -Dsearch.server.limit.timeout in rsed.envvars.
