Oracle11g RAC开启关闭、设置归档小结
2014-10-14来源:易贤网

关闭

1.先关数据库:

代码如下:

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

2.再关闭crs服务

代码如下:

root@oeltan1 ~]# crsctl stop crs

启动:

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

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:

代码如下:

# su - grid

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

SQL> select name from V$asm_diskgroup;

NAME

--------------------------------------------------------------------------------

CRS

DATA1

FRI

12 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:

123 ASMCMD> pwd +FRI/TANTEST ASMCMD> mkdir ARCH2

2.修改归档参数

任意一个实例,oracle用户下:

12 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:

1234 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:

12345678910111213141516 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>
