Will RESET INTEGRITY on one VSAM database affect any of the other VSAM databases ?
No, running RESET INTEGRITY (MAIL) will not affect any of the other TPX VSAM databases (ADMIN1, ADMIN2, NOTES, VIEW).
Same is true for any other TPX database.
RESET INTEGRITY must only be run when the TPX started task is INACTIVE.
It is recommended that RESET INTEGRITY should be run on ALL databases at regular intervals.
