DB2 Integration - first full offline database backup

Hi,

according to documentation, to enable online backups of DB2, "First backup up the database offline to non-Data Protector media"

Why offline backup must be done, and how to avoid that?


From documentation:
Before you begin
To enable online backups of DB2 objects, set the DB2 logretain and userexit parameters to ON (in a partitioned environment, on every node on which the object resides). Then restart the database for the new parameters to take effect and perform a full offline database backup.

Problem
Online backup is not allowed
DB2 reports:
Online backup is not allowed because either logretain or userexit for roll-forward is not activated, or a backup pending condition is in effect for the database.
Action
After configuring the DB2 database for rollforward recovery (userexit and logretain ON), first back up the database offline. If online backup is started first, the above error is reported.



Thanks & Regards,
Tom
