Oracle11g RAC开启关闭、设置归档小结
人气:0这篇文章主要介绍了Oracle11g RAC开启关闭、设置归档,很简单,但很实用,需要的朋友可以参考下
关闭
1.先关数据库:
复制代码 代码如下:
[oracle@oeltan1 ~]$ srvctl stop database -d tantest
[
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
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>
