Can you please explain why we are getting the TSS9103E during the startup, although we have DD VSAMFILE and VSAMBKUP in the start up procedure.
Environment
Release: Component: TSSMVS
Resolution
The answer depends on whether or not you share your secfile among systems.
You can check issuing a TSS MODI STATUS(BASE), look for TSS control option SHRFILE(NO).
If you have SHRFILE(NO), be sure the secfile is not shared. If SHRFILE(YES), allocate the VSAM PATH file and update your TSS procedure accordingly. If SHRFILE(YES) but you the secfile is NOT shared then correct your TSSPARM0 member specifying SHRFILE(NO) which will improve performance and avoid this message.
