Parameters that must have identical in RAC database:
In a RAC database there may contain several instances and the initialization parameters of all of the instances should not have identical setting. In fact the initialization parameters that are critical for database creation and affect certain database operations must have the same value for every instance in an Oracle RAC database.
Below is the list of initialization parameters that must have identical settings for all instances in a RAC database.
1)ACTIVE_INSTANCE_COUNT
2)ARCHIVE_LAG_TARGET
3)CLUSTER_DATABASE
4)CLUSTER_DATABASE_INSTANCES
5)COMPATIBLE
6)CONTROL_FILES
7)DB_BLOCK_SIZE
8)DB_DOMAIN
9)DB_FILES
10)DB_NAME
11)DB_RECOVERY_FILE_DEST
12)DB_RECOVERY_FILE_DEST_SIZE
13)DB_UNIQUE_NAME
14)DML_LOCKS (Only if set to zero).
15)INSTANCE_TYPE (RDBMS or ASM)
16)PARALLEL_MAX_SERVERS
17)REMOTE_LOGIN_PASSWORD_FILE
18)UNDO_MANAGEMENT
