  • 2.5 Set Up the Environment to Support the Standby Database

Step 1   Create a Windows-based service.-linux操作下面不用操作这一步
Step 2   Create a password file. 2.4.1已经创建
Step 3   Configure listeners for the primary and standby databases.
Step 4   Create Oracle Net service names.

Step 5   Create a server parameter file for the standby database.

[oracle@ocm2 ~]$ export ORACLE_SID=PRODSTD
[oracle@ocm2 ~]$ sqlplus "/as sysdba"

Connected to an idle instance.

SYS@PRODSTD>create spfile from pfile;

File created.


  • 2.6.Start the Physical Standby Database
启动备库

Step 1   Start the physical standby database.

SYS@PRODSTD>startup mount
ORACLE instance started.

SYS@PRODSTD>
备库
SYS@PRODSTD>select database_role,switchover_status from v$database;

DATABASE_ROLE    SWITCHOVER_STATUS
---------------- --------------------
PHYSICAL STANDBY RECOVERY NEEDED
主库
SYS@PROD>select database_role,switchover_status from v$database;

DATABASE_ROLE    SWITCHOVER_STATUS
---------------- --------------------
PRIMARY          SESSIONS ACTIVE

Step 2   Start Redo Apply.

备库只有在mount状态的时候可以应用日志,read only状态不能应用日志
应用日志调用2个MRP进程启动LEO3库日志应用并后台运行
alter database recover managed standby database disconnect from session parallel 2;

备库
SYS@PRODSTD>alter database recover managed standby database disconnect from session parallel 2;

Database altered.

SYS@PRODSTD>select database_role,switchover_status from v$database;

DATABASE_ROLE    SWITCHOVER_STATUS
---------------- --------------------
PHYSICAL STANDBY SESSIONS ACTIVE

主库
SYS@PROD>select database_role,switchover_status from v$database;

DATABASE_ROLE    SWITCHOVER_STATUS
---------------- --------------------
PRIMARY          SESSIONS ACTIVE

Step 3   Test archival operations to the physical standby database.

SYS@PROD>alter system switch logfile;

System altered.

  • 2.7 Verify the Physical Standby Database Is Performing Properly

Step 1   Identify the existing archived redo log files.

SYS@PRODSTD>SELECT SEQUENCE#, FIRST_TIME, NEXT_TIME,applied from v$archived_log;

 SEQUENCE# FIRST_TIM NEXT_TIME APP
---------- --------- --------- ---
        11 25-MAR-14 25-MAR-14 YES
        12 25-MAR-14 25-MAR-14 YES


Step 2   Force a log switch to archive the current online redo log file.

SYS@PROD>ALTER SYSTEM SWITCH LOGFILE;

System altered.

Step 3   Verify the new redo data was archived on the standby database.
Step 4   Verify new archived redo log files were applied.

SYS@PRODSTD>SELECT SEQUENCE#, FIRST_TIME, NEXT_TIME,applied from v$archived_log;

 SEQUENCE# FIRST_TIM NEXT_TIME APP
---------- --------- --------- ---
        11 25-MAR-14 25-MAR-14 YES
        12 25-MAR-14 25-MAR-14 YES
        13 25-MAR-14 25-MAR-14 YES
