I have an issue with backing up two SAP datafiles using rman, the only thing it points to is the Datafiles are bigger that 2Gb. i tested this by changing the size of one of the three datafiles to less than 2 Gb, it then backed up fine using RMAN, unfortunately i have 4 other systems that i have to do and am unable to keep doing the same thing for each.

Please can someone let me know what i can look at or change to stop this nagging little problem.

Below are the details of the system

HP-UX 11.11
Oracle :
