The file obrindex.dat on the Cell Manager grows with each IDB backup performed. It is stored in the following locations:
- %DP_SDATA_DIR%server\db80\logfiles\rlog (Windows)
- /var/opt/omni/server/db80/logfiles/rlog/obrindex.dat (Linux)
- Copy of the file as defined in RecoveryIndexDir to the global file
It is never purged and becomes pretty big over the time containing mostly irrelevant information (on unprotected IDB backups). It should only contain information for protected IDB backups.
It would be no longer needed to manually purge this file in environments that have been running for a long time and/or a large number of IDB backups.
