Notes on DMSTVI
Following are notes on DMSTVI:
- If your site chooses to use OS Simulation Support, you may need to modify some site-defined EXECs to make them compatible with CMS’s OS Simulation processing. See the Command Reference Guide for full details.
- The INSTALL parameter is valid only when running VMTTVI, not when running DMSTVI.
- CMS OS Simulation will call DMSTVI, if available, in preference to DMSTVS. If DMSTVI does not exist and DMSTVS does, DMSTVS will be called. If neither DMSTVI nor DMSTVS exist, the standard end-of-volume action is performed by CMS. See the CMS user’s guide for your system for further details.
Note: If you use DMSTVS instead of DMSTVI, you must issue SET TVICALL OFF before starting the tape application.
- DMSTVI and DMSTVS cannot be used with the CA VM:Tape Bin system.
- Both VMTTVI and VMTTVS are automatically loaded to the public file disk at installation, usually the VMANAGER 193 disk.
- If you are switching to VMTTVI, any EXECs written for VMTTVS may not run without some modification.
Note: When running OS simulation tape applications that mount tapes using an IBM 3494 using the CA VM:Tape RMS interface, you must issue SET TAPECSL OFF on the CMS user ID that is running the application. This helps prevent CMS from interfering with CA VM:Tape 3494 tape processing.
- If you are using an IBM 3494 controlled tape device, ensure you set TAPECSL OFF.
