DY47566: LBSERV IQUERY DOES NOT RELEASE ALLOCATED GETVIS FROM SUBPOOL $AOMGV IN A TIMELY MANNER AND MAY FAIL WITH RC=0008 REASON=0076

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When invoking the LBSERV IQUERY macro (e.g. via the JCC/JCL
  LIBSERV IQUERY command), the allocated system GETVIS in the
  subpool $AOMGV is not directly released after the completion of
  the request.

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users with a tape library using the native   *
  *                 VSE Tape Library Support (SYS ATL=TLS).      *
  ****************************************************************
  * PROBLEM DESCRIPTION: When invoking the LBSERV IQUERY macro   *
  *                      (e.g. via the JCC/JCL LIBSERV), the     *
  *                      the allocated system GETVIS in the      *
  *                      subpool $AOMGV is not directly released *
  *                      after the completion of the request.    *
  ****************************************************************
  * RECOMMENDATION: Apply the PTF if you use a tape library      *
  *                 with the native VSE Tape Library Support     *
  *                 (SYS ATL=TLS) and have a very large amount   *
  *                 of volumes in the library.                   *
  ****************************************************************
  The LBSERV IQUERY processing in $IJBAOM allocates a temporary
  buffer from the system GETVIS area in subpool $AOMGV to hold
  inventory data for each volume in the library. This buffer is
  not directly FREEVISed after the request completes. It is
  FREEVISed when a following LBSERV request completes.
  
  The user may observe the following behavior:
  In a series of LIBSERV/LBSERV IQUERY requests the first request
  completes successfully, but allocated GETVIS in subpool $AOMGV
  is not released. A second request may fail with
  RC=0008 REASON=0076 if the system GETVIS area is exhausted. The
  previously allocated GETVIS in subpool $AOMGV is now released,
  allowing a following request to complete successfully.
  

Problem conclusion

• The PTF adds code to FREEVIS the allocated buffer once the
  IQUERY request completes.
