Could someone please tell me where I can download a manual for RMAN, or go to look up error codes? I've been looking on google as well as the Oracle website, and haven't had any luck. Here is my problem; When trying to delete obsolete RMAN backupsets, I get an error: RMAN> change backupset 698, 702, 704, 708 delete; List of Backup Pieces BP Key BS Key Pc# Cp# Status Device Type Piece Name ------- ------- --- --- ----------- ----------- ---------- 698 698 1 1 AVAILABLE SBT_TAPE df_546210555_706_1 702 702 1 1 AVAILABLE SBT_TAPE df_546296605_709_1 704 704 1 1 AVAILABLE SBT_TAPE df_546383776_712_1 708 708 1 1 AVAILABLE SBT_TAPE df_546469964_715_1 Do you really want to delete the above objects (enter YES or NO)?

I can't find any more useful detail than this. Thanks, Drake -- //www.freelists.org/webpage/oracle-l
