I would start by validating the archived redo log on the primary. That should help determine a direction for the solution and establish whether the corruption is primary or a network artifact.

Subject: Standby Log corruption -- in Recover phase

Hi All,
I am trying to set up RAC to RAC dataguard between 2 databases in different data centers.
I am able to ship archivelogs from primary to DR. The logs are not getting applied.

In the standby alert log -- I see the following errors (several of these CORRUPTION DETECTED Errors)

*CORRUPTION DETECTED: In redo blocks starting at block 4097count 2048 for
thread 4 sequence 15019*
RFS[1185]: Possible network disconnect with primary database *Deleted Oracle managed file

another thing is -- I have any another application, where there is dataguard from RAC to single instance. For this I dont see any problem..

can anybody throw some light on this problem?

Thanks in advance..

Krishna
