BCB contains corrupt block ranges in datafile backups. BCF contains control file backups (in backup sets). BDF contains all datafile backups (in backup sets). BP contains all backup pieces of backup sets. BRL contains backup redo logs (in backup sets). BS contains all backup sets for all database incarnations. CCB contains corrupt block ranges in datafile copies. CCF contains control file copies. CDF contains all datafile copies. CKP records all recovery catalog checkpoints. DB contains all target databases that have been registered in this recovery catalog. DBINC contains all incarnations of the target databases registered in this recovery catalog. DF contains all datafiles of all database incarnations. DFATT datafile attributes that change over time. OFFR stores datafile offline ranges. ORL contains all redo logfiles for all database incarnations. RCVER recovery catalog version. RLH records all redo log history for all threads. RR contains redo ranges for all database incarnations. RT redo threads for all database incarnations. SCR contains 1 row for each stored script. SCRL contains 1 row for each line of each stored script. TS contains all tablespaces of all database incarnations. TSATT tablespace attributes that change over time.
