If you are upgrading from Release 6.0.x, run the job TBOL604 in your.prefix.CNTL or TBOL604V if you are using VSAM libraries. Modify the JCL in either of these members to conform to your installation standards.
The job creates a new library by copying the tables from your version of the TBAPPLB library. There are two commands in this job:
The CHANGE command changes the definition of the TBOLPROF table to be upgraded to the current level.
The DELETE command deletes temporary tables from the past install procedure.
These commands inside the jobs, TBOL604 and TBOL604V are not mandatory but there is no harm in rerunning the process in case the previous upgrade did not install properly.
This step produces a directory listing of all the tables remaining in the TBAPPLB library. This directory listing is used to prepare the next two steps: Upgrade 2—Update message tables and Upgrade 3—Update security module (optional)
