Database FlashSnap and Active Data Guard
In environments where the Oracle Active Data Guard feature (available in Oracle 11g) is used, redo log application must be stopped explicitly on standby database before taking a database snapshot.
To use Database FlashSnap in an Active Data Guard environment
-
Stop redo log apply.
For example:
SQL>ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
-
Run dbed_update.
-
Create a snapplan and validate it.
-
Take a snapshot.
-
Start redo log apply.
For example:
SQL>ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT;
-
Clone the snapshot.
