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>
