【实验】Oracle 10g RAC生产数据库RMAN方式恢复到异地单机数据库全程记录
【前言】这是一个RMAN备份有效性验证的过程。源端环境介绍：
生产数据库是包含两个节点的Oracle 10g 10.2.0.3 RAC数据库：
ASM管理+裸设备
数据库名：racdb第一节点的sid：racdb1第一节点的sid：racdb2异地单机数据库（恢复Server）介绍：单机
单实例
低配
下面将详细记录整个从RAC到单机的详细恢复过程。【实验BEGIN】1.将源端的RMAN备份的所有文件拷贝到恢复Server上脚本如下，注意这里使用了一个保证scp不会中断的小技巧（sleep）racdb1@testdb183 /orabak$ cat scp.shnohup scp -r oracle@172.193.192.26:/orabak/* /orabak &sleep 102.修改源端生成的pfile文件，去掉与RAC有关的内容。将ASM格式的文件路径统统的修改成为文件系统路径的格式。修改之前的pfile：racdb1@testdb183 /oracle$ cat initracdb1.ora_backup_originracdb2.__db_cache_size=6543114240racdb1.__db_cache_size=6056574976racdb1.__java_pool_size=16777216racdb2.__java_pool_size=16777216racdb1.__large_pool_size=16777216racdb2.__large_pool_size=16777216racdb2.__shared_pool_size=1795162112racdb1.__shared_pool_size=2281701376racdb1.__streams_pool_size=0racdb2.__streams_pool_size=0*.audit_file_dest=/oracle/app/oracle/admin/racdb/adump*.background_dump_dest=/oracle/app/oracle/admin/racdb/bdump*.cluster_database_instances=2*.cluster_database=true*.compatible=10.2.0.3.0*.control_files=+ORADATA/racdb/controlfile/current.256.668538019*.core_dump_dest=/oracle/app/oracle/admin/racdb/cdump*.db_block_size=8192*.db_create_file_dest=+ORADATA*.db_domain=*.db_file_multiblock_read_count=16*.db_name=racdbracdb2.instance_number=2racdb1.instance_number=1*.wbj_queue_processes=10*.local_listener=local_listener_rac*.log_archive_dest_1=LOCATION=+ORADATA/racdb/*.log_archive_format=%t_%s_%r.arch*.open_cursors=300*.pga_aggregate_target=2088763392*.processes=800*.remote_listener=LISTENERS_racdb*.remote_login_passwordfile=exclusive*.sessions=885*.sga_max_size=5242880000racdb1.sga_max_size=8388608000racdb2.sga_max_size=8388608000*.sga_target=1610612736racdb1.sga_target=8388608000racdb2.sga_target=8388608000racdb2.thread=2racdb1.thread=1*.undo_management=AUTOracdb2.undo_tablespace=UNDOTBS2racdb1.undo_tablespace=UNDOTBS1*.user_dump_dest=/oracle/app/oracle/admin/racdb/udump修改之后的pfile：racdb1@testdb183 /oracle$ cat initracdb1.ora*.audit_file_dest=/oracle/app/oracle/admin/racdb/adump*.background_dump_dest=/oracle/app/oracle/admin/racdb/bdump*.compatible=10.2.0.3.0*.control_files=/oracle/oradata/racdb/control01.ctl*.core_dump_dest=/oracle/app/oracle/admin/racdb/cdump*.db_block_size=8192*.db_domain=*.db_file_multiblock_read_count=16*.db_name=racdb*.wbj_queue_processes=10*.log_archive_format=%t_%s_%r.arch*.open_cursors=300*.pga_aggregate_target=2088763392*.processes=800*.remote_login_passwordfile=exclusive*.sessions=885*.sga_max_size=524288000*.sga_target=161061273*.undo_management=AUTO*.undo_tablespace=UNDOTBS1*.user_dump_dest=/oracle/app/oracle/admin/racdb/udump3.根据上面参数文件内容，在恢复Server上创建确实的目录$ mkdir -p /oracle/app/oracle/admin/racdb/cdump$ mkdir -p /oracle/app/oracle/admin/racdb/udump$ mkdir -p /oracle/app/oracle/admin/racdb/adump$ mkdir -p /oracle/app/oracle/admin/racdb/bdump4.登陆恢复端Server的RMAN命令行，设置成设置成生产RAC第一节点的dbid（这个需要提前确认好）racdb1@testdb183 /oracle$ rman target /Recovery Manager: Release 10.2.0.3.0 - Production on Mon Aug 24 20:32:13 2009Copyright (c) 1982, 2005, Oracle.
