I am running DATACOM in SIMPLIFY mode and need to change the CXX name .

Question:

How can I do this?

Environment:
z/OS CA Datacom 14.0 (and higher)
Answer:
  1. Shut down the Datacom Multi-User normally
  2. Run a DBUTLTY BACKUP of the CXX
  3. Run the assembly/link-edit on DBSIDPR after changing CXXNAME from 

    CXXNAME=old name to CXXNAME=new name 

  4. Run DBUTLTY INIT/LOAD CXX using the CXX Backup from step 2
