备份主数据库

$ rman target /

CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT   '/mnt/sdb1/rman/full_%u_%s_%p';
RMAN> BACKUP DATABASE PLUS ARCHIVELOG;

# 默认将备份到Flash Recovery Area.

为备数据库创建控制文件和PFILE

ALTER DATABASE CREATE STANDBY CONTROLFILE AS '/tmp/goposstb.ctl';
CREATE PFILE='/tmp/initgoposstb.ora' FROM SPFILE;

SQL> ALTER DATABASE CREATE STANDBY CONTROLFILE AS '/tmp/goposstb.ctl';

Database altered.

SQL> CREATE PFILE='/tmp/initgoposstb.ora' FROM SPFILE;

File created.

修改PFILE /tmp/initgoposstb.ora

*.audit_file_dest='/u01/app/oracle/admin/goposstb/adump'
*.control_files='+GOWMS_DATA/gopos/controlfile/current.276.917608579','+GOWMS_DATA/gopos/controlfile/current.277.917608579'
*.db_file_name_convert='gopos','goposstb'
*.db_unique_name='goposstb'
*.fal_server='gopos'
*.log_archive_dest_2='SERVICE=gopos ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=gopos'
*.log_file_name_convert='gopos','goposstb'

首先登录备数据库创建以下目录

#mkdir -p /mnt/sdb1/oracleData/gopos
#mkdir -p /u01/app/oracle/fast_recovery_area/gopos
#mkdir -p /mnt/sdb1/oracleData/gopos/adump

mkdir -pv /u01/app/oracle/admin/goposstb/adump

复制两个文件至备数据库

scp /tmp/initgoposstb.ora oracle@goposstb:/u01/app/oracle/product/11.2.0/db_1/dbs/
scp /tmp/goposstb.ctl oracle@goposstb:/mnt/sdb1/oracleData/gopos/control01.ctl
scp /tmp/goposstb.ctl oracle@goposstb:/mnt/sdb1/oracleData/rman/control02.ctl

复制password file和备份文件

cd /u01/app/oracle/product/11.2.0/db_1/dbs/
scp orapwgopos oracle@goposstb:/u01/app/oracle/product/11.2.0/db_1/dbs/

cd /mnt/sdb1/rman/
scp -r gopos oracle@goposstb:/mnt/sdb1/rman/

备数据库服务器操作

注：可选？！首先更改db_unique_name为对应的名称。

alter system set db_unique_name='goposstb' SCOPE=SPFILE;
select db_unique_name from v$database;
# OR:
show parameter unique;

确认listener启动正常

lsnrctl status

从备份中恢复数据库(可选方法）

恢复控制文件

export ORACLE_SID=gopos
sqlplus / as sysdba

SQL> CREATE SPFILE FROM PFILE='/tmp/initgoposstb.ora';

恢复数据库

export ORACLE_SID=gopos
rman target /

RMAN> STARTUP MOUNT;
RMAN> list backup of database summary;
RMAN> RESTORE DATABASE;

Note: Recovery of database would be failed with RMAN-06054 error, We can ignore it because RMAN will ask for unknown archive log ( i.e. next archive log sequence, i.e. 10 ) who is not also available on Primary database.

Error log: RMAN-06054: media recovery requesting unknown archived log for thread 1 with sequence 10 and starting SCN of 1009554

创建日志文件

ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT=MANUAL;
ALTER DATABASE ADD LOGFILE ('+GOWMS_REDO') SIZE 4G;
ALTER DATABASE ADD LOGFILE ('+GOWMS_REDO') SIZE 4G;
ALTER DATABASE ADD LOGFILE ('+GOWMS_REDO') SIZE 4G;
ALTER DATABASE ADD LOGFILE ('+GOWMS_REDO') SIZE 4G;
ALTER DATABASE ADD LOGFILE ('+GOWMS_REDO') SIZE 4G;
ALTER DATABASE ADD LOGFILE ('+GOWMS_REDO') SIZE 4G;
ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT=AUTO;

在主和备数据库中创建STANDBY LOGFILE( +1 redo file )

ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT='MANUAL';
ALTER DATABASE ADD STANDBY LOGFILE ('+GOWMS_REDO') SIZE 4G;
ALTER DATABASE ADD STANDBY LOGFILE ('+GOWMS_REDO') SIZE 4G;
ALTER DATABASE ADD STANDBY LOGFILE ('+GOWMS_REDO') SIZE 4G;
ALTER DATABASE ADD STANDBY LOGFILE ('+GOWMS_REDO') SIZE 4G;
ALTER DATABASE ADD STANDBY LOGFILE ('+GOWMS_REDO') SIZE 4G;
ALTER DATABASE ADD STANDBY LOGFILE ('+GOWMS_REDO') SIZE 4G;
ALTER DATABASE ADD STANDBY LOGFILE ('+GOWMS_REDO') SIZE 4G;
ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT='AUTO';

ALTER DATABASE DROP LOGFILE GROUP 10;

使用RMAN自动复制主数据库至备数据库

主备数据库切换操作

=== Enable Data Guard Broker == http://www.juliandyke.com/Research/DataGuard/DataGuardBroker.php

Both gopos/goposstb

SQL> ALTER SYSTEM SET dg_broker_start = TRUE;

Start DGMGRL

dgmgrl

Create Data Guard Broker Configuration

dgmgrl
 CREATE CONFIGURATION DG1 AS PRIMARY DATABASE IS 'gopos'
 CONNECT IDENTIFIER IS 'gopos';

 Configuration "DG1" created with primary database "gopos"

Add standby database(s)

 dgmgrl
 ADD DATABASE 'goposstb' AS CONNECT IDENTIFIER IS 'goposstb';

Enable the configuration

 dgmgrl
 ENABLE CONFIGURATION

Switchover to standby

 dgmgrl
DGMGRL> SWITCHOVER TO 'goposstb'

Switchback

 dgmgrl
DGMGRL> SWITCHOVER TO 'gopos'

手动从主gopos切换至备goposstb

CONNECT / AS SYSDBA
ALTER DATABASE COMMIT TO SWITCHOVER TO STANDBY;

关闭主gopos数据库，挂载主数据库为“备”数据库工作

SHUTDOWN IMMEDIATE;
STARTUP NOMOUNT;
ALTER DATABASE MOUNT STANDBY DATABASE;
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;

备数据库(goposstb)执行接管操作

CONNECT / AS SYSDBA
ALTER DATABASE COMMIT TO SWITCHOVER TO PRIMARY;
SHUTDOWN IMMEDIATE;
STARTUP;

切换回去的话，重启执行一遍，反方向。

主数据库故障手动切换操作

在备goposstb数据库执行

ALTER DATABASE RECOVER MANAGED STANDBY DATABASE FINISH;
ALTER DATABASE ACTIVATE STANDBY DATABASE;

Read-Only Standby and Active Data Guard

To switch the standby database into read-only mode, do the following.

SHUTDOWN IMMEDIATE;
STARTUP MOUNT;
ALTER DATABASE OPEN READ ONLY;

select name,open_mode,database_role from v$database;

To resume managed recovery, do the following.

SHUTDOWN IMMEDIATE;
STARTUP MOUNT;
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;

select name,open_mode,database_role from v$database;

Remove dataguard

alter database recover managed standby database disconnect from session; alter database recover managed standby database cancel;

ERROR: failed to establish dependency between database goposstb and diskgroup resource ora.GOWMS_ARCH.dg

This error is harmless.

It is documented in the internal Bug 8304720 "ERROR: FAILED TO ESTABLISH DEPENDENCY BETWEEN DB & DISKGROUP"

"The db-dg dependency will be created later on if the diskgroup is used by the db again; the dependency can also be created manually through cmdline tool. Automatically it will resolve itself later on when the db tries to use the diskgroup. Or we can manually establish the dependancy through any command line utility."
