一條命令搞定ADG

最近一直在搭建ORACLE 12C ADG ，其中包括單機到單機的ADG, RAC到RAC的ADG，還有RAC到單機的ADG，遇到不少小問題，在此做一下記錄。

Oracle 12c R1 RAC 修改啟動方式

$srvctl modify database -d orcldg -s nomount  orcldg為數據庫名

$srvctl modify database -d orcldg -s mount  

$srvctl modify database -d orcldg -s open  

置完DATAGUARD之后，默認是mount，但是我們要求自動啟動成ADG模式，這里就需要做一個小小的改動。

1.查看啟動方式

$srvctl config database -d orcldg

Database unique name: orcldg

Database name:

Oracle home: /u01/app/oracle/product/12.1.0/dbhome_1

Oracle user: oracle

Spfile: +DATADG/orcldg/spfileorcldg.ora

Password file: +DATADG/orcldg/PASSWORD/pworcldg

Domain:

Start options: mount

Stop options: immediate

Database role: PHYSICAL_STANDBY

Management policy: AUTOMATIC

Disk Groups: DATADG

Services:

OSDBA group:

OSOPER group:

Database instance: orcldg

 2.修改啟動方式

$srvctl modify database -db orcldg -startoption open

3.在此驗證啟動方式

<orcldg:orcldg:/home/oracle>$srvctl config database -d orcldg

Database unique name: orcldg

Database name:

Oracle home: /u01/app/oracle/product/12.1.0/dbhome_1

Oracle user: oracle

Spfile: +DATADG/orcldg/spfileorcldg.ora

Password file: +DATADG/orcldg/PASSWORD/pworcldg

Domain:

Start options: open

Stop options: immediate

Database role: PHYSICAL_STANDBY

Management policy: AUTOMATIC

Disk Groups: DATADG

Services:

OSDBA group:

OSOPER group:

Database instance: orcldg

4.啟動數據庫，查看open_mode 已經啟動為ADG模式了
