Oracle11g RAC开启关闭、设置归档小结

关闭 1.先关数据库: 复制代码 代码如下: [oracle@oeltan1 ~]$ srvctl stop database -d tantest 2.再关闭crs服务 [复制代码 代码如下: root@oeltan1 ~]# crsc

关闭

1.先关数据库:

复制代码 代码如下:

[oracle@oeltan1 ~]$ srvctl stop database -d tantest
2.再关闭crs服务
[
复制代码 代码如下:

root@oeltan1 ~]# crsctl stop crs

启动:

复制代码 代码如下:

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

上述开机一般已经启动
复制代码 代码如下:

[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:

复制代码 代码如下:

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

SQL> select name from V$asm_diskgroup;

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

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:

ASMCMD> pwd
+FRI/TANTEST
ASMCMD> mkdir ARCH2

2.修改归档参数
任意一个实例,oracle用户下:

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:

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:

SQL> archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination +FRI/tantest/arch1
Oldest online log sequence 14
Next log sequence to archive 15
Current log sequence 15

SQL> archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination +FRI/tantest/arch2
Oldest online log sequence 6
Next log sequence to archive 7
Current log sequence 7
SQL>
