Oracle11g RAC开启关闭、设置归档小结

关闭

1.先关数据库:

 

[oracle@oeltan1 ~]$ srvctl stop database -d tantest

2.再关闭crs服务



root@oeltan1 ~]# crsctl stop crs

启动:

 


[root@oeltan1 ~]# crsctl start crs
[oracle@oeltan1 ~]$srvctl start asm -n node_name

上述开机一般已经启动

 

[oracle@oeltan1 ~]$ srvctl start database -d tantest
归档设置:

 

1. 分别创建两个实例的ASM目录
任意一个实例,grid用户下:

 

# su - grid
[grid@oeltan1 ~]$ sqlplus "/as sysasm"

SQL> select name from V$asm_diskgroup;

NAME
--------------------------------------------------------------------------------
CRS
DATA1
FRI

 

?
1
2
SQL> alter diskgroup FRI add directory '+FRI/TANTEST';
SQL> alter diskgroup FRI add directory '+FRI/TANTEST/ARCH1';

还可以通过asmcmd创建目录:

?
1
2
3
ASMCMD> pwd
+FRI/TANTEST
ASMCMD> mkdir ARCH2

2.修改归档参数
任意一个实例,oracle用户下:

?
1
2
ALTER SYSTEM SET LOG_ARCHIVE_DEST_1='LOCATION=+FRI/TANTEST/ARCH1' SCOPE=both SID='tantest1';
ALTER SYSTEM SET LOG_ARCHIVE_DEST_1='LOCATION=+FRI/TANTEST/ARCH2' SCOPE=both SID='tantest2';

3.两个节点上分别都执行:

?
1
2
3
4
SQL> SHUTDOWN IMMEDIATE;
SQL> STARTUP MOUNT;
SQL> ALTER DATABASE ARCHIVELOG;
SQL> ALTER DATABASE OPEN;

--修改一个实例时,另一个实例不能在open状态,否则报ORA-01126: database must be mounted in this instance and not open in any

4.分别检查:
