Starting Up a Physical Standby Database
========================================

1.Start and mount the physical standby database:
————————————————-

SQL> STARTUP MOUNT;

2.Start Redo Apply or real-time apply:
————————————–

To start Redo Apply, issue the following statement:
—————————————————

SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;

To start real-time apply, issue the following statement:
——————————————————–

SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE;

Note: On the primary database, query the RECOVERY_MODE column in the V$ARCHIVE_DEST_STATUS view,
which displays the standby database’s operation as MANAGED_RECOVERY for Redo Apply
and MANAGED REAL TIME APPLY for real-time apply.

Shutting Down a Physical Standby Database
==========================================

1.Issue the following query to find out if the standby database is performing Redo Apply or real-time apply.
If the MRP0 or MRP process exists, then the standby database is applying redo.

SQL> SELECT PROCESS, STATUS FROM V$MANAGED_STANDBY;

2.If Redo Apply is running, cancel it as shown in the following example:

SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;

3.Shut down the standby database.

SQL> SHUTDOWN IMMEDIATE;
