    *                 Internal Interface function to monitor and   *

    * PROBLEM DESCRIPTION: 1. When the SA for z/OS BCPii function  *
    *                      terminates a session to the mainframe   *
    *                      processor support element, HSAET32      *
    *                      component leaves 1290 bytes in the CSA  *
    *                      storage plus additional control blocks  *
    *                      in main storage causing CSA storage     *
    *                      shortage.                               *
    *                      2. Large capacity records available on  *
    *                      the zEC12 are not completely showed     *
    *                      by TCDATA command.                      *
    *                      3. Memory overlay in INGCHW00 Module    *
    *                      caused by large XML data returned       *
    *                      by the System z API.                    *
    ****************************************************************
    * RECOMMENDATION: NetView recycle is required in order to      *
    *                 apply this APAR fix (SINGMOD1 changed).      *
    *                 Recycling the NetView Address Spaces does    *
    *                 NOT free CSA/ECSA storage already allocated  *
    *                 by NetView: a system IPL is required.        *
    ****************************************************************
    Module INGCHW0D has been changed to support dynamic memory
    allocation for XML   data returned by the System z API for
    TCDATA, STPDATA and GETIPSW commands.
    Module HSAPHCPR has been changed to free HW session storage
    at the TERMCOM request.
    

Problem conclusion

  • Termination of a SA BCPii session removes all session related
    data from CSA and main storage preventing storage shortage and
    possible outages. CSA/ECSA gotten prior to fix apply can only
    be freed by IPL.  Dynamic memory allocation allows handling
    of large capacity records.
