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

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>
