Issue/Introduction
The ACF2 Infostorage(INFOSTG) record size of the ACF2 databases was increased to activate the RULELONG RULEOPTS.
The /F ACF2,BACKUP command create a file with a record size of 4K instead of 12k for the Infostorage and resources databases. Is that normal?
Environment
Release : 16.0
Resolution
Both the ACF2 manual 'F ACF2,BACKUP' command and the automatic backup will create the ACF2 backup sequential files with the LRECL and BLKSIZE as needed. So if/when a site has rules greater than 4K the sequential backup RULES and INFOSTG files created from the ACF2 backup will have the appropriate LRECL and BLKSIZE(>4K) required for the IDCAMS REPRO.
Additional Information
The ACF2 installation CAX1JCL0 library contains JCL to define the ACF2 backup sequential datasets, the following are portions of the sample JCL related to the ACF2 sequential backup files for the ACF2 databases:
