在vmware下配置ORACLE的RAC+DG讲课讲稿.doc

在vmware下配置ORACLE的RAC+DG精品文档在vmware下配置ORACLE的RAC+DG我用虚拟机装了rac+ a Single Instance Physical Standby已经配置成功了。并能进行自动的切换.我在这里就先贴一个,其实这个帖子我在这个联接很久就发布.但是还有好多朋友没有发现( .

)以上在配置好要进行相应的测试，也测试能否连同各个数据库5安装和配置pri-rac上的参数文件initdevdb.ora文件安装和配置pri-rac上的参数文件initdevdb.ora文件，并配置好相应的密码文件和dataguard的相关参数。其实initdevdb.ora文件可以从RAC1或者RAC2的机器上COPY过来，然后再把带有RAC的项目去掉$sqlpluc /nologSQLconn / as sysdbaSQLcreate pfile from spfile;scp $ORACLE_HOME/dbs/initdevdb1.ora pri-ra:$ORACLE_HOME/dbs再修改相应的的参数，以下是pri-rac上的initdevdb.ora文件内容：oraclepri-rac dbs$ cat

-备用库上的归档日志目录*.standby_file_management=AUTO*.fal_server=devdb*.fal_client=standby在这里一定要注意db_file_name_convert，log_file_name_convert参数的值配置，在RMAN恢复他的时候，要采用，如且一定要保证配置的正确。同时也要创建好相应的目录$ORACLE_BASE/admin/devdb/bdump cdump这些相应的目录，如果感觉难创建可以直接从RAC1或者RAC2上COPY过来，然后修改下alter_devdb.log文件，就OK了。6配置NFS在PRI-RAC上配置修改pri-rac备库机器上的/etc/exports文件oraclepri-rac dbs$ cat /etc/exports/home/oracle/product/backup *(async,rw)添加此行。启动portmap service portmap start启动NFS service NFS startrootpri-rac # service nfs restart关闭 NFS mountd：失败关闭 NFS 守护进程：失败关闭 NFS quotas：失败关闭 NFS 服务： 失败启动 NFS 服务： 确定关掉 NFS 配额：确定启动 NFS

/home/oracle/product/backup上面此目录要在RAC1和RAC2上分别挂载上。到此准备工作已经完成。下面要开始备份RAC库，以及他的控制文件和日志文件二、为physical standby库备份RAC数据库在做好以上这些准备后，我们就可以开始备份RAC数据库了。全库备份RAC数据库以及控制文件run allocate channel c1 device type disk
