When maintenance is applied to the Message Service Server (MSS) and/or the Data Mover then it's needed to deploy this to the lpars it's installed on and the lpars that also are connection to the application that is using them, like MOI (Mainframe Operational Intelligence)..
How to accomplish this task?
z/OS
Mainframe Operational Intelligence
CA Common Services
After the SMPE installation of the maintenance it's needed to copy 5 ZFS file systems from the SMPE environment to the runtime environment:
The server-id.txt file can be found in the following MSS USS directory: <mount_point>/cfgb/instance/
It's also recommended to delete the contents of the directory <Install_Dir>/cfgb/instance/messageService/brokerData.
This directory has a sub-directory with ActiveMQ database and it changes with the new server-id. So the old directory would stay without being deleted.
It does not do any harm but it takes up some space.
