ORACLE RAC 11.2（12C)正确关闭顺序

                              ORACLE RAC 11.2（12C)正确关闭顺序

       在11.2后的版本中crs被称为gi,通过crsctl stop cluster来关闭整个实例的资源非常
方便，但是对于数据库实例需要单独关闭,stop cluster对于实例直接以非正常的方式结束.环境是
基于12C的.

正确的顺序:

先关闭数据库

[oracle@rac1 ~]$ srvctl stop database -db tt

alert.log显示是通过immediate方式关闭.

Sat Apr 19 05:12:19 2014
Shutting down instance (immediate)

Sat Apr 19 05:12:33 2014
SMON: disabling tx recovery
Sat Apr 19 05:12:33 2014

确认一下配置oracle实例是不是immediate方式来关闭的。

[oracle@rac1 ~]$ srvctl config database -db tt
Database unique name: tt
Database name: tt
Oracle home: /u01/app/oracle/product/12.1.0.0/db_1
Oracle user: oracle
Spfile: +DATA/tt/spfilett.ora
Password file: +DATA/tt/orapwtt
Domain:
Start options: open
Stop options: immediate
Database role: PRIMARY
Management policy: AUTOMATIC
Server pools: tt
Database instances: tt1,tt2
Disk Groups: DATA
Mount point paths:
Services:
Type: RAC
Start concurrency:
Stop concurrency:
Database is administrator managed
[oracle@rac1 ~]$

 

错误的方法:

为图省事,直接关闭整个cluster

[root@rac1 ~]# crsctl stop cluster -all

alert.log显示实例是非常结束

License high water mark = 6
Sat Apr 19 05:15:14 2014
USER (ospid: 5792): terminating the instance
Sat Apr 19 05:15:14 2014
opiodr aborting process unknown ospid (3667) as a result of ORA-1092
Sat Apr 19 05:15:15 2014
Instance terminated by USER, pid = 5792


由此可以看出通过stop cluster来关闭实例会非常危险，直接是以非正常的方式来关闭实例的.


重启实例可以看到恢复操作
