I have some questions relate to RMAN backup our databases are ORACLE version
10.2.0.4 and 11.1.0.7.
1. setup init.ora file parameters "db_block_checking = true". How much
overhead it will have?
2. when RMAN backup parameter "check logical" what major difference. (e.g.
between "backup check logical database" and "backup database")
if I remember correctly RMAN "backup database" default will check corruption
block and head/tail checksumming. Am I correct?
Thanks.
