Datafile (system ) corrupted on physical standby database
Hi, I need some expert advice please:
Our environment: RAC-RAC dataguard, DB: Oracle 11gR2, ASM, SAN storage, OS: RHEL5
DR site have physical standby database.
Problem: We had a power failure on our DR site. As a result SAN and DB server were down illegally. After we fixed power and hardware, I was trying to open database in read only mode to check. Until database mount state it works well. But when I am trying to open, I am having the following error
alter database open

ERROR at line 1:
ORA-10458: standby database requires recovery
ORA-01196: file 1 is inconsistent due to a failed media recovery session
