oracle 11g rac 归档开启-白红宇

背景：

数据库建设到现在，一致在做逻辑备份，考虑到后期维护人员现场情况，建议最近就将归档日志打开

过程

因为之前没有在rac开启过归档，现在在虚拟rac下测试下如果归档路径放到某个节点，或者放到存储中

grid>asmcmd

>ls

cd DATADG/

cd arch

mkdir arch

pwd

[ ~]# su - oracle

[ ~]$ export ORACLE_SID=PROD1

[ ~]$ sqlplus "/as sysdba"

SQL> alter system set log_archive_dest_1='location=+DATADG/arch' scope=spfile sid='*';

System altered.

SQL> ALTER SYSTEM SET log_archive_format='arch_%t_%s_%r.arc' SCOPE=spfile;

System altered.

关闭数据库，全部节点都要关闭

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

srvctl stop database -d PROD

srvctl start database -d PROD -o mount

[ ~]# su - oracle

[ ~]$ export ORACLE_SID=PROD1

[ ~]$ sqlplus "/as sysdba"

实战中

节点二的集群关闭，高可用关闭，

后来重新启动都在报错，

是在没招了，重启了节点二机器，重启后发现数据库还在重启中，但是集群已经启动了
