1、修改目录
将两个节点的归档修改到本地文件系统下
节点1归档到/arch1
节点2归档到/arch2
2、创建本地目录
节点1：
#mkdir -p /arch1
#chown -R oracle:oinstall /arch1
#chown -R 775 /arch1
节点2：
#mkdir -p /arch2
#chown -R oracle:oinstall /arch2
#chown -R 775 /arch2
3、修改归档（任一节点操作）
SQL>alter system set log_archive_dest_1='location='/arch1' scope=spfile sid='oratest1';
SQL>alter system set log_archive_dest_1='location='/arch2' scope=spfile sid='oratest2';
4、重启到mount状态
节点1：
SQL>shutdown immediate;
SQL>startup mount;
节点2：
SQL>shutdown immediate;
SQL>startup mount;
5、打开库
两个节点依次打开
SQL>alter database open;
6、查看归档
节点1：
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination /arch1
Oldest online log sequence 23
Next log sequence to archive 24
Current log sequence 24
节点2：
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination /arch2
Oldest online log sequence 23
Next log sequence to archive 24
Current log sequence 24
7、日志切换测试
SQL>alter system switch logfile;
8、rman备份数据库及两节点本地归档日志到共享nfs目录
节点1（192.192.103.85）server:
---创建nfs共享目录---
mkdir -p /backup
#vi /etc/exports
/backup * (rw,sync,no_roo_squash,no_all_squash)
---生效nfs目录---
#exportfs -a
---启动nfs服务---
#service rpcbind start
#service nfs start
---查看nfs共享信息---
#showmount -e
/backup *
节点2（192.192.103.86）client：
---创建目录---
#mkdir -p /backup
---检查nfs server共享目录信息---
#showmount -e 192.192.103.85
---mount nfs共享目录---
#mount -t nfs -o rw 192.192.103.85:/backup /backup
---编辑fstab文件--
#vi /etc/fstab
192.192.103.85:/backup /backup nfs defaults 0 0
---启动nfs服务---
#service rpcbind start
#service nfs start
-----两节点配置TNSNAMES.ora文件-----
