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 <world>(rw,wdelay,root_squash,no_subtree_check,anonuid=65534,anongid=65534) 节点2 [root@rac2 arch]# showmount -e rac1 Export list for rac1: /u02/arch * [root@rac2 arch]# mount -t nfs -o rw,bg,hard,nointr,rsize=32768,wsize=32768,timeo=600,actimeo=0 rac1:/u02/arch /u02/arch [root@rac2 arch]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 17G 13G 2.9G 82% / /dev/sda1 99M 12M 82M 13% /boot tmpfs 792M 454M 338M 58% /dev/shm rac1:/u02/arch 17G 11G 5.0G 69% /u02/arch [root@rac2 ~]# vi /etc/fstab /dev/VolGroup00/LogVol00 / ext3 defaults 1 1 LABEL=/boot /boot ext3 defaults 1 2 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 /dev/VolGroup00/LogVol01 swap swap defaults 0 0 rac1:/u02/arch /u02/arch nfs rw,bg,hard,nointr,rsize=32768,wsize=32768,timeo=600,actimeo=0 0 0
