Problem summary

  • ****************************************************************
    * USERS AFFECTED: 01.All RDz users                             *
    ****************************************************************
    * PROBLEM DESCRIPTION: 01.Timeout threads in RDz server are    *
    *                         not terminated every time when       *
    *                         client requests remote z/OS search.  *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    01.When search.server.limit.timeout is set to a fairly long time
       (ex. 300 seconds) and there are many matched entries on
       remote z/OS search, many timer threads remain even if most
       of them are not required.
    

Problem conclusion

  • 01.Server code is updated to terminate the timeout thread every
       time when a client request is completed to process.
    

Temporary fix
