Startup Nomount

ALTER DATABASE mount standby database;

Main Library Execution:

Startup Mount

ALTER DATABASE set standby database to maximize availability; (set to highest availability mode)

ALTER DATABASE open;

Sql>alter database recover managed standby database disconnect from session;

# After this command is executed, the standby will switch to the automatic recovery mode

First, function switching

Switchover State switching

First, operate on the primary:

(1). Verify that the main library is able to perform role conversions to the standby repository (primary repository execution)

Sql> SELECT switchover_status from V$database;

Switchover_status

-----------------

To STANDBY

1 row selected

(2) Start to change the physical master library to a physical repository (primary repository execution)

Sql> ALTER DATABASE COMMIT to switchover to physical STANDBY;

Or

Sql> ALTER DATABASE COMMIT to switchover-physical STANDBY with session shutdown;

Note: If this option is available for an active session, the conversion encounters a ORA-01093 error or can be converted after an active session or an active session is killed

(3). Close and restart the main library (primary library execution)

sql> shutdown Immediate

Sql> Startup Nomount

Sql> ALTER DATABASE mount standby database; #让备库处于standby

sql> ALTER DATABASE recover managed standby database using current logfile disconnect from session; #开始实时同步

Then operate on the standby:

(1). Verify that the repository can perform role conversions to the main library (original repository execution)

Sql> SELECT switchover_status from V$database;

Switchover_status

-----------------

To_primary

1 row selected

(2). Start converting a physical repository to a physical master (original repository execution)

Sql> ALTER DATABASE COMMIT to switchover to PRIMARY;

--If the ora-16139:media recovery required is reported, it may be because the log is not applied, you can first execute

ALTER database RECOVER MANAGED STANDBY database DISCONNECT from SESSION;

(3) Open the standby, and then turn off the restart. (Original repository execution)

Sql> SHUTDOWN IMMEDIATE;

Sql> STARTUP;

(4) Verify the conversion is successful (original repository execution)

sql> ALTER SYSTEM SWITCH LOGFILE;

Start the Log app

(5) Apply archive log (performed on the primary repository)

sql> ALTER database RECOVER MANAGED STANDBY database USING current LOGFILE DISCONNECT from SESSION;

Tip: To implement switchover smoothly, it's a good idea to set some initialization parameters for primary and standby at the same time on each server, although some of these parameters only work on one of the primary or standby.

4. Start and close sequence

Boot order

(1). Boot from, the main library monitoring listener

From library Dg-standby:

$lsnrctl start

Main Library Dg-primary:

$lsnrctl start

(2). Start the repository database and do the following:

$sqlplus/nolog

Sql>conn/as SYSDBA

Sql> Startup Nomount

Sql> ALTER DATABASE mount standby database; #让备库处于standby

sql> ALTER DATABASE recover managed standby database using current logfile disconnect from session; #开始实时同步

(3). Start the main library

$sqlplus/nolog

Sql>conn/as SYSDBA

Sql> Startup

Toggle Standby Database to read only mode

sql> ALTER DATABASE recover managed standby database cancel; #首先取消备库的自动恢复模式

Sql>alter database open Read only;

If you want to switch back to recover Manage mode (Start log app or start log Live app)

sql> ALTER DATABASE recover managed standby database disconnect from session; Start the Log app

Sql>alter database recover managed standby database using current logfile disconnect from session; Launch log real-time application

(3). Start the main library database (after the second step above, you can execute the following command):

Sql>startup

Close Order

On the contrary, close the main library, and then close from the library.

(1). Close the main library

$su –oracle

Sql>sqlplus/nolog

Sql>conn/as SYSDBA

Sql>shutdown immediate;

(2). Close from library

Su–oracle

Sql>sqlplus/nolog

Sql>conn/as SYSDBA

Sql>alter database recover managed standby database cancel; #停止同步

Sql>shutdown Immediate

Emergency switching

(Note: Simulation of the main library due to failure is not normal switchover, need to perform failover, force the library->pridb and take over the business)

(1). Prepare the Library:

Since it is a failover, understanding the main library is not working properly at this time, only the standby library switches to PRIDB

Stop Applying recovery mode

ALTER DATABASE recover managed standby database finish;

Convert Standbydb to Primary db

ALTER DATABASE commit to switchover to primary;

Restart the database to resume normal business

Sql>shutdown Immediate

Sql>startup

Select Open_mode,database_role from V$database;

Open_mode Database_role

----------             ----------------

OPEN PRIMARY

Note: Failover will break the Dataguard mode, need to reconfigure the Dataguard, the web also said no need to configure, but has not been tested successfully

Select Dbid,name,protection_mode,protection_level from V$database;
