The U2805 abend is caused by one of the following having occurred:
TSSFAR was run against the live secfile.
TSSFAR is properly running against a current backup file but while the report is running a backup is taken against the backup file.
Resolution
TSSFAR should never be run against the live secfile. A backup should be taken just before running the report. **Commands to take a backup are: ***From a command line: TSS MODIFY(BACKUP) ***From the console: F TSS,BACKUP
The reason that the abend occurs is that TSSFAR encounters an invalid ARLB. In either instance, starting over with a new backup and TSSFAR pointing to the new backup, will run the report successfully.
