Issue/Introduction

How to change/increase/enlarge the allocation of a CA Disk FILES Data Set (FDS) 

Environment

Release: All

Resolution

Unload the current records (UNLOAD) and reload (RELOAD) them into a new FDS as follows:

1. Stop CA Disk Batch processing, no IXMAINT, MERGE, etc. 
2. UNLOAD the existing FDS with UNLOAD ALL and keep the SEQFILES output as input for the following RELOAD (and of course as a Backup). Keep the FDS Status Report produced by the UNLOAD for double-checking after the RELOAD. 
3. Change the key length of the RETEXCL subfile in your FILEDEFN member from 50 to 44. This is the default and the delivered FILEDEFN in the CCUWPARM library should show this. 
4. Run FILEINIT to allocate and initialize a new FILES Data Set, e.g. cadisk.FDS.NEW. You may check already at this point a FDS Status Report of the new empty FDS against a FDS Status Report of the existing FDS. 
5. Specify the new cadisk.FDS.NEW in the FILES DD of the RELOAD. Run RELOAD with command RELOAD ALL,FORMAT,FREESP=20 using the SEQFILES from the previous UNLOAD. 
6. Check the FDS Report from the RELOAD against the FDS Status report from the UNLOAD. 
7. Rename the existing cadisk.FDS to cadisk.FDS.OLD 
8. Rename the new cadisk.FDS.NEW to cadisk.FDS 
9. Run basic test jobs like Backup, Archive, Restore, etc. to verify all is ok.
