今天就跟大家聊聊有关 oracle11g RAC 启动归档模式的示例分析，可能很多人都不太了解，为了让大家更加了解，丸趣 TV 小编给大家总结了以下内容，希望大家根据这篇文章可以有所收获。

根据客户要求，需要将归档日志存放在 ASM 上。因此需要在 ASM 建归档路径

ASMCMD mkdir arch

ASMCMD cd arch

ASMCMD pwd
+data1/kdcs/arch

修改归档路径参数

SQL alter system set log_archive_dest_1= location=+data1/kdcs/arch scope=spfile sid= *

System altered.

关闭数据库，全部节点都要关闭

[grid@zhcs-db1 ~]$ srvctl stop database -d kdcs

检查数据库关闭后状态

[grid@zhcs-db1 ~]$ crsctl stat res -t
