AIX 上 oracle 10.2.0.3 数据库开启归档手顺
检查系统空间查看系统是否有充足的空间：df创建归档目标目录：mkdir /arch1 /arch2检查oracle 安装用户并改变归档目录所有权：chown oracle:oinstall /arch1 /arch2开启nfs服务：touch /etc/exportsmknfs –Nmkfs –llssrc –g nfs导出nfs共享smit mknfsexpexportfs –ashowmount –e localhost添加nfs的预定义挂载smit mknfsmnt#vi /etc/filesystems应该对应为/arch2: dev = /arch2 vfs = nfs log = /tmp/nfslog node=racnode2 mount = true options = rw,soft,bg account = false测试挂载nfsmount /arch1或mount /arch2做冷备：两个节点shutdown immediate一个节点startup mount exclusiveORACLE_SID=racdb1 rman target /configure backup optimization on;configure controlfile autobackup on;backup as copy database;然后打开两个数据库在两个系统上做alter system set log_archive_dest_1='LOCATION=/arch1' scope=spfile sid='racdb1'; alter system set log_archive_dest_1='LOCATION=/arch2' scope=spfile sid='racdb2';切换rac archivelogalter system set cluster_database=false scope=spfile sid='*'; shutdown immediate startup mount exclusivearchive log listalter database archivelog;archive log listalter system set cluster_database=true scope=spfile sid='*';shutdown immediatestartupalter system switch logfile;几次做验证，结束
