Nologging will invalidate your physical standby since it is no longer a block-by-block copy of the primary. Fast way is to identify all files that witnessed this operation by checking 'v$datafile.unrecoverable_time' and just copy these files over and resume recovery.

I personally would rebuild it, unfortunately since you're not in 11g, you can't just take a copy of the current database but I'l defer my answer as a hard/fast rule based on what others say.

Hi List,

Quick Q: We've a dataguard physical standby that we cloned, and the clone bonked on:

GATHER_STATS_JOB encountered errors. Check the trace file. Errors in file
/u01/app/oracle/admin/DSTEST01/bdump/dstest01_j001_10559.trc:

ORA-01578: ORACLE data block corrupted (file # 185, block # 36931)
ORA-01110: data file 185: '/u07/oradata/DSTEST01/edwindx37_4m.dbf'
ORA-26040: Data block was loaded using the NOLOGGING option 

We see this error multiple times, all for various datafiles within one of our index tablespaces.

I checked the primary and oops, it appears that it was *not* in force logging mode. This has since been corrected, but my question is this: Do we have to rebuild the standby to ensure consistency? There are zero errors on the physical standby, and the only indication of a problem is the above after a cloning operation.

Thanks- Chris
