Issue/Introduction

There are two SARXMS regions in use, a primary region and a secondary region, for VTAM users.

Once the primary region reaches the USERMAX limit, users are passed to the secondary region.

Those in the secondary region experience the following hang:

Environment

Release : 14.0

Component : CA View

Cause

The root problem was found to be in TPX, where the PCIF 5F vector was not being tracked.

Resolution

It was suggested that the SARXMS parameter VTAMPASS be set to VTAMPASS=YES on all of the SARXMS tasks, rather than just the primary task, so that there would not be any hang condition in either of the tasks.

To allow View to move users to a second SARXMS region, once the USERMAX parameter value was reached in the first region, the client made the following TPX update:

. Reserve Option 18 must be turned on to use 57 Vector.
