There are no supplied TPX utilities to merge the ADMIN VSAM files. This must be accomplished via VSAM utilities, but it is a tricky process and must be done carefully.
You may be able to use IDCAMS REPRO process to populate a file then use the REPRO with NO REPLACE to continue the population of the file. A sort is not necessary as long as it is the cluster name (e.g. ADMIN2) and not the data name (e.g. ADMIN2.DATA) in use for the REPRO.
- Make sufficient copies of your files before attempting any merging of the files.
- Don't forget to RESET INTEGRITY when finished.
To determine the storage for a new consolidated TPX, add up all of the individual storage amounts from the previous TPXs. Ideally, use D STORXA displays in each original TPX to see what the high water marks are and add those up.
