How to revert to the primary NIMSM host address when it is back up

Issue/Introduction

When using ADDRESS USS SMREQ from OPS/MVS to generate CA NIM incidents it is possible to include an alternate server in case the primary server fails. For example:

CA_OPS_CANIMSM_HOST="nimhost1,nimhost2"

If nimhost1 is down, OPS/MVS automatically tries to connect to nimhost2 and continues to use this secondary server for the next requests.
However, OPS/MVS never retries nimhost1 unless nimhost2 fails.
How to make OPS/MVS revert to the primary NIMSM host address when it is back up?

Environment

OPS/MVS

Cause

This is working as designed. OPS/MVS won't attempt to connect to a server that was known as down because this would create an additional overhead. It always tries to connect to the server of the last successful connection. 

Resolution

There is a workaround that is to recycle the OPSUSS servers:

1. Go to the OPSVIEW panel 4.3
2. Put "USS" in the "CLASS" field at the right of the screen
3. You will see a list of USS servers
4. Use the "T" line command to terminate the servers

The next ADDRESS USS SMREQ will attempt to connect to the primary NIM host.
