OA40327: ABEND878 FOR BELOW THE LINE STORAGE WHEN DSIPRT IS RUNNING IN THE NETVIEW ADDRESS SPACE.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• An abend878 occurred for the NetView asid for below the line
  storage due to SP0 Key 8 containing ACBs for DSILT. DSILT is
  a dataset used during DSIPRT which was running under an autotask
  within NetView. Since NetView doesn't pass a storage address
  when issuing the gencb the storage is gotten below the line.
  Normally when DSIPRT is running as a job, when the job completes
  the asid goes away and the storage is freed. But when DSIPRT is
  running under NetView, the storage is not freed until NetView
  is shut down.

  ****************************************************************
  The NetView log print program, DSIPRT, prepares to read a
  NetView log file (VSAM cluster) by obtaining an exit list
  (EXLST), access method control block (ACB), and a request
  parameter list (RPL), among other things.  For each block,
  (EXLST, ACB, and RPL) the macro (GENCB) used to create the
  block is invoked in a manner such that DFSMSdfp (VSAM)
  obtains the storage for the block "below the 16M line" (that
  is, in 24-bit addressable storage), in addition to formatting
  it.
  When DSIPRT completes processing of the NetView log file,
  however, it does not free the storage that GENCB obtained.
  When DSIPRT is run as job step program in its own job, this is
  not a problem, because the storage is freed upon termination
  of the address space created for the job.  If DSIPRT is run
  using a REXX command environment, such as LINKMVS, in a NetView
  REXX EXEC or if DSIPRT is run as a NetView subtask, address
  space termination does not follow program termination, so the
  storage is not freed.  With repeated execution of DSIPRT in
  NetView, eventually "below the 16M line" storage is exhausted,
  resulting in the x'878' abend.
  

Problem conclusion

• Part DSIPRT is being changed to save the length and address of
  each piece of storage (EXLST, ACB, and RPL) and free them when
  finished with the processing of the NetView log file.
