Cause: The DB_FILE_STANDBY_NAME_CONVERT or LOG_FILE_STANDBY_NAME_CONVERT initialization parameters are not the same as in other instances that already have the database mounted. See the solution below.
Error solution: Change initialization parameters DB_FILE_STANDBY_NAME_CONVERT and LOG_FILE_STANDBY_NAME_CONVERT to match other instances.
Database version: Oracle 11g Release 2 (11.2)
