a.如果备份的数据库可以访问，那么执行执行生产转化脚本： select 'set newname for datafile ' || file# || ' to ''' ||replace( name,'/old/data/path','/new/data/path' ) || ''';' from v$datafile;
b.如果备份的数据库不可以访问，可以trace控制文件内容： alter database backup controlfile to trace; 在alert查看生成的trace文件路径和名称；
编辑恢复脚本： vi recover.txt
run{ allocate channel c1 type sbt; allocate channel c2 type sbt; allocate channel c3 type sbt; allocate channel c4 type sbt; allocate channel c5 type sbt; allocate channel c6 type sbt; allocate channel c7 type sbt; allocate channel c8 type sbt; set newname for datafile 1 to '/s01/oracle/oradata/prod/system.156.952859152'; set newname for datafile 2 to '/s01/oracle/oradata/prod/sysaux.157.952859154'; set newname for datafile 3 to '/s01/oracle/oradata/prod/undotbs1.258.952859453'; set newname for datafile 4 to '/s01/oracle/oradata/prod/users.159.952855153'; set newname for datafile 5 to '/s01/oracle/oradata/prod/undotbs2.168.956859305'; set newname for datafile 6 to '/s01/oracle/oradata/prod/data.176.952859731'; set newname for datafile 7 to '/s01/oracle/oradata/prod/data.177.952857539'; set newname for datafile 8 to '/s01/oracle/oradata/prod/data.178.952850557'; restore database; switch datafile all; recover database; release channel c1; release channel c2; release channel c3; release channel c4; release channel c5; release channel c6; release channel c7; release channel c8; }
放在后台恢复： nohup rman target / @recover.txt log backup.log &
