Output Tape CLOSE Process Steps

  1. An SVC call, implemented using an operating system intercept, is issued out of CLOSE.
  2. The TLMSCLSE module gains control, builds a CA TLMS type 1 transaction, and issues the TLMSQMGR SVC (without wait).
  3. The TLMSQMGR gains control, receives the transaction, and cross-memory posts TLMSMAIN.
  4. TLMSMAIN is activated by the cross-memory post.
  5. TLMSMAIN responds to the post by calling TLMSMSGQ.
  6. TLMSMSGQ receives a copy of the transaction through an SVC call to TLMSQMGR. It then calls the label processing routines in TLMSVMRW.
  7. TLMSUPDT accesses the Volume Master File specified in the CTS procedure through routines in its copy of TLMSVMRW.
  8. The VMF is accessed by volume serial number (VSN).
  9. The retrieved VMF record is updated with the new data set name and with run statistics.
  10. (Optional) A copy of the transaction is written to the Alternate Log file if the RECOVRY system option is set to ALTLOG.
  11. TLMSMSGQ is notified that the update is complete.
