Issue/Introduction

We have 3 LPARs that were linked and synced on 12.1.

They were unlinked, upgraded to 12.2, data was migrated, and now we are trying to link and synchronize the regions with /MADMIN.SD.
The process fails with
RMSY6907 INVALID VALUE. ACCESS METHOD TCPIP HAS BEEN EXCLUDED

This error indicates that the access methods in the /PARMS $RM MULTISYS are not the same on the local and remote regions when attempting to synch the databases.

Review of the parameter group shows this on both systems

Why is this not working?

Environment

Release : 12.2

Component : CA NetMaster Suite

Resolution

The regions were initialized using a modified 12.1 INIFILE to migrate the settings to 12.2, as per the doc recommendations.

As a result, the $NM SOCKETS parameter group initializes with TYPE=IBM.
The default for 12.2 is TYPE=USS, and this is required for the product to function correctly.

To correct the problem, do these two steps on all involved regions:

1. Update the SOCKETS parameter group from TYPE IBM to TYPE USS.
    Check the second screen to ensure the stack name is correct and the Netmaster OBEYFILE exists.
    Action the parameter group with F6 and ensure it completes correctly.

2. Select the MULTISYS  parameter group with U ((update).
    Action the parameter group with F6.
    Check the ILOG (F5 from the parameter group, or option L from the menu) and verify it has activated with the current timestamp.


Retry the link and sync process, which should now run successfully.
