    * PROBLEM DESCRIPTION: 01.searching for a string in a PDS      *
    *                         consumes too much CPU.               *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    01.Some searches consumed too much CPU because the search could
       not stop until the number of matched results reached the
       limit the client specified or all the selected data sets were
       searched.
    

Problem conclusion

  • 01.The RDz server is enhanced to support limitations for the
       number of search matches, lines, and files.
       And the server and client were altered to stop the search
       when the search reached the limitations.
       The server limits are specified in rsed.envvars variables
       _RSE_JAVAOPTS -Dsearch.server.limit.hits=300
       _RSE_JAVAOPTS -Dsearch.server.limit.datasets=200
       _RSE_JAVAOPTS -Dsearch.server.limit.lines=100000
