If you have CICSPlex® SM Web
User Interface servers connected to CMASs other than the maintenance
point CMAS, which have many other MASs connected to them, you might
not want to upgrade the other MASs at the same time as the CMAS. In
that case, consider using this phased upgrade path.
About this task
Assuming you are running the latest CICSPlex SM maintenance
levels, you can upgrade one LPAR at a time.
Procedure
- Define a new Version 5.2 CMAS on the same z/OS® image as the Web User Interface server.
- Define CMAS to CMAS links between the new Version 5.2 CMAS and the maintenance point CMAS in the CICSplex where the
Web User Interface server CMAS is connected.
- Upgrade the maintenance point CMAS in the CICSplex to Version 5.2.
- Assign the new Version 5.2 CMAS to the CICSplex.
- Upgrade the Web User Interface server to Version 5.2 and, when you restart it, connect it to the Version 5.2 CMAS. If the Web User Interface server is configured
to connect specifically to the original CMAS, you must change the
configuration to connect to the Version 5.2 CMAS.
- Upgrade the remaining MASs to Version 5.2 when required, and connect them to the Version 5.2 CMAS as you restart them. If the MASes are configured
to connect specifically to the original CMAS, you must change their
configuration to connect to the Version 5.2 CMAS.
- When you have moved all the MASs to the Version 5.2 CMAS, you can remove the original CMAS from the CICSplex, and
delete CMAS to CMAS links between the original CMAS and the other
CMASes in the CICSplex.
