Cause of the Problem
Scenario 01: If your Oracle database version is 8i and you are able to activate the standby database with no errors, however, each time you try to open the standby database in read only mode it fails with the above errors, then possibly it is due to READ_ONLY_OPEN_DELAYED parameter setting.
Scenario 02:
If database files reside on an ocfs and datafiles appear to corrupt to nodes other than "node1" (instance1) in a RAC then problem happened because filesystem was mounted with the "reclaimid" option.
Solution of the Problem
Solution for Scenario 01:
Set READ_ONLY_OPEN_DELAYED parameter to false and then you will be able to open the database in read only mode.
SQL> Alter system set READ_ONLY_OPEN_DELAYED = FALSE scope=spfile;
SQL> shut immediate
SQL> startup
Solution for Scenario 02:
While mounting do not use the reclaimid mount option for "normal" mounts. This option should only be used once after having to regenerate the guid of a node after ip address change.
