Recommendations and Procedures for IBM VTS Without IMPORT/EXPORT

The following usermod must be installed to provide support for the IBM VTS without the IMPORT/EXPORT feature:

• CTSJUCBX—Applies your customized source to CBRUXENT, CBRUXEJC (and optionally CBRUXVNL) to your z/OS linklib

The following CA 1 system parameters and procedures should also be set:

• ROBSCR=YES—Set in TMOOPTxx member of CTAPOPTN to enable real-time scratch processing.
• WRKFLS=NO—Set in TMOOPTxx member of CTAPOPTN. This causes CA 1 to assign a 1 day retention to all work files.
• If YSVC=YES you must update your security system to give OAM update access to resource YSVCUNCD.

Run your normal daily CA 1 maintenance jobs and when TMSCLEAN runs, it notifies the VTS of which tapes have been scratched. All tapes (virtual volumes) remain within the VTS.
