Question/Problem Description
Incremental online backup has the same size as a full online backup, even if the incremental backup was created right after the full backup.
Offline incremental probkups are also the same size as a full probkup.
Steps to Reproduce
Clarifying Information
Truncating the bi prior to incremental probkup makes no difference.
Once the size problem manifests, every incremental probkup is the same size as a full probkup.
Dropping the incremental overlap factor -io probkup parameter makes no difference to the backup volume size.
Not using the redundancy -red probkup parameter.
Error Message
Defect/Enhancement NumberDefect OE00200066
Cause
The exact cause is not known at this time.
Possibly an overflow on the master block incremental backup counter (bk_incr), which is used to determine which database blocks to include in the incremental backup.
Resolution
Dump and load the database in order to re-set the block counters.
