To migrate a single-region CICS EJB/CORBA server to
CICS® Transaction Server for z/OS®, Version 3 Release 1:
- Quiesce the workload.
- Shut down the region.
- Upgrade the region to CICS Transaction Server for z/OS, Version 3 Release 1, following the standard migration
procedures described in CICS Transaction Server
for z/OS Migration from CICS TS Version version_number, where version_number is the version number of your back-level CICS release.
- Review Migration tips, which describes some of the changes in
EJB/CORBA support between CICS TS for z/OS, Version 2.2 and CICS Transaction Server for z/OS, Version 3 Release 1. You should also
refer to Setting up a single-region EJB server, which describes in detail how to set up a
single-region EJB server in CICS TS for z/OS, Version 3.1.
- Restart the region.
- Republish the Interoperable Object References (IORs) for all the enterprise
beans and stateless CORBA objects processed by the server. To do this, issue
a PERFORM CORBASERVER(CorbaServer_name) PUBLISH command.
This command can be issued using EXEC CICS, CEMT, the Resource Manager for
enterprise beans, or from a CICSPlex SM EUI or WUI view. Remember to issue
a separate command for each CorbaServer in the region.
