Problem summary

  • ****************************************************************
    * USERS AFFECTED: All File MAnager Editor Users.               *
    ****************************************************************
    * PROBLEM DESCRIPTION: The FIND command in comparison to       *
    *                      ISPF, uses much more CPU and takes      *
    *                      longer for files with many records.     *
    ****************************************************************
    * RECOMMENDATION: Apply the provided PTF.                      *
    ****************************************************************
    File Manager was not handling internal buffers as intended while
    processing the FIND command.
    

Problem conclusion

  • The FIND command performance has been improved for datasets with
    many records that are not loaded in entirety to virtual storage.
    The improvement in performance is dependant upon size of the
    region, size of the data and more heavily the number of records.
