Upgrading a single-region CICS EJB/CORBA server

To migrate a single-region CICS EJB/CORBA server to CICS® Transaction Server for z/OS®, Version 3 Release 1:
  1. Quiesce the workload.
  2. Shut down the region.
  3. 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.
  4. 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.
  5. Restart the region.
  6. 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.
