11g RAC修改归档模式
11g RAC修改归档步骤
1：节点修改归档路径
2：停止数据库-srvctl stop database -d fyl
3：启动数据库至mount--srvctl stop database -d fyl -o mount
4：实例分别执行alter database archivelog;
[grid@rac1 ~]$ srvctl stop database -d fyl
3：启动数据库至mount
[grid@rac1 ~]$ srvctl start database -d fyl -o mount
4：实例分别执行alter database archivelog;
1：节点修改归档路径
2：停止数据库-srvctl stop database -d fyl
3：启动数据库至mount--srvctl stop database -d fyl -o mount
4：实例分别执行alter database archivelog;
5：验证
1：节点修改归档路径
创建NFS共享文件系统存放归档日志（rac1 ：nfs server ；rac2：nfs client）
节点1
[root@rac1 arch]# vi /etc/exports
/u02/arch *(rw,sync)
[root@rac1 arch]# chkconfig nfs on
[root@rac1 arch]# service nfs start
Starting NFS services: exportfs: No options for /u02/arch *: suggest *(sync) to avoid warning
exportfs: No host name given with /u02/arch (rw,sync), suggest *(rw,sync) to avoid warning
exportfs: incompatible duplicated export entries:
exportfs: *:/u02/arch (0x424) [IGNORED]
exportfs: *:/u02/arch (0x425) [ OK ]
Starting NFS quotas: [ OK ]
Starting NFS daemon: [ OK ]
Starting NFS mountd: [ OK ]
[root@rac1 arch]# exportfs -v
/u02/arch (rw,wdelay,root_squash,no_subtree_check,anonuid=65534,anongid=65534)
