    This problem is described as follows:
      1. VTAM obtains the storage for the VTAM Internal trace
         table from the high virtual common (HVCOMM) storage
         above the 2-gigabyte bar.
      2. D NET,BFRUSE command output does not include the
         VTAM the HVCOMM storage usage.
    

Problem conclusion

  • ISTATCVT has been changed to provide the current HVCOMM
    storage usage, maximum storage usage counters and constant
    of 2048 megabytes for the HVCOMM storage limit for the
    VTAM Internal trace (VIT) table. ISTRACTI has been changed
    to update HVCOMM storage usage and maximum storage usage
    counters when it obtains or frees the storage for the VIT
    table.
    ISTINCNO,ISTCFCMM,ISTCFCWM,ISTVTMEU and MSG2400 have been
    changed to define the messages IST2403I and IST2405I for
    the HVCOMM storage usage and the limit. ISTNOCDB has been
    changed to display the HVCOMM storage usage and the limit.

      Explanation:
      This message is the first in a group of messages that VTAM
      issues in response to a DISPLAY BFRUSE command. This message
      is a header message for the 64-bit storage usage display of
      storage above the bar. A complete description of the message
      follows.
    
    IST2403I 64-BIT  STORAGE TYPE        CURRENT   MAXIMUM     LIMIT
    IST2405I         TRACE HVCOMMON curhvcommtr maxhvcommtr limhvcom
    
      IST2403I
        This message is a header message for the 64-bit storage
        information displayed in the messages that follow this
        message.
    
      IST2405I
    
        curhvcommtr is the current amount of HVCOMM storage
        allocated for the VTAM Internal Trace table.
    
        maxhvcommtr is the maximum amount of HVCOMM storage
        allocated for the VTAM Internal Trace table.
    
        limhvcom is the maximum amount of HVCOMM storage that
        can be allocated for the VTAM Internal Trace table.
    
    Example:
    IST2403I 64-BIT  STORAGE TYPE        CURRENT   MAXIMUM     LIMIT
    IST2405I         TRACE HVCOMMON           2M        4M     2048M
