一、背景
oracle：11.2.0.3 单机 通过tsm备份软件备份（什么玩意不太读懂，反正就是调用rman接口备份）。这是客户的一套OA的数据库，现在需要通过tsm做个恢复测试演练。
二、撸起袖子，开干
2.1 还原参数文件，忘记记录（略）
2.2 还原控制文件
run{ allocate channel t1 type 'sbt_tape' parms 'ENV=(tdpo_optfile= /opt/tivoli/tsm/client/oracle/bin64/tdpo.opt)'; restore controlfile from 'NEROA_cntrl_12753_1_1023216458'; release channel t1; }
2.3 还原数据库
run { allocate channel t1 type 'sbt_tape' parms 'ENV=(tdpo_optfile= /opt/tivoli/tsm/client/oracle/bin64/tdpo.opt)'; set newname for datafile 1 to '/rmanbak/oracle/oradata/NEROA/system01.dbf'; set newname for datafile 2 to '/rmanbak/oracle/oradata/NEROA/sysaux01.dbf'; set newname for datafile 3 to '/rmanbak/oracle/oradata/NEROA/undotbs01.dbf'; set newname for datafile 4 to '/rmanbak/oracle/oradata/NEROA/users01.dbf'; set newname for datafile 5 to '/rmanbak/oracle/oradata/NEROA/NEROA.dbf'; set newname for datafile 6 to '/rmanbak/oracle/oradata/NEROA/NEROA_TEST.dbf'; set newname for datafile 7 to '/rmanbak/oracle/oradata/OATEST.dbf'; set newname for datafile 8 to '/rmanbak/oracle/oradata/NEROA/oalinuxtest.dbf'; set newname for datafile 9 to '/rmanbak/oracle/oradata/NEROA/system02.dbf'; set newname for datafile 10 to '/rmanbak/oracle/oradata/NEROA/NEROA02.dbf'; set newname for datafile 11 to '/rmanbak/oracle/oradata/NEROA/sysaux02.dbf'; set newname for datafile 12 to '/rmanbak/oracle/oradata/NEROA/system03.dbf'; set newname for datafile 13 to '/rmanbak/oracle/oradata/NEROA/system04.dbf'; set newname for datafile 14 to '/rmanbak/oracle/oradata/NEROA/system05.dbf'; set newname for datafile 15 to '/rmanbak/oracle/oradata/NEROA/system06.dbf'; set newname for datafile 16 to '/rmanbak/oracle/oradata/NEROA/NEROA03.dbf'; set newname for datafile 17 to '/rmanbak/oracle/oradata/NEROA/system07.dbf'; set newname for datafile 18 to '/rmanbak/oracle/oradata/NEROA/system08.dbf'; set newname for datafile 19 to '/rmanbak/oracle/oradata/NEROA/system09.dbf'; set newname for datafile 20 to '/rmanbak/oracle/oradata/NEROA/NEROA04.dbf'; set newname for datafile 21 to '/rmanbak/oracle/oradata/NEROA/NEROA05.dbf'; restore database; release channel t1; } --别问我为什么只开一个通道，我也想知道为什么开多个会报错
2.4 注册数据文件为datafilecopy
catalog datafilecopy '/rmanbak/oracle/oradata/NEROA/system01.dbf'; catalog datafilecopy '/rmanbak/oracle/oradata/NEROA/sysaux01.dbf'; catalog datafilecopy '/rmanbak/oracle/oradata/NEROA/undotbs01.dbf'; catalog datafilecopy '/rmanbak/oracle/oradata/NEROA/users01.dbf'; catalog datafilecopy '/rmanbak/oracle/oradata/NEROA/NEROA.dbf'; catalog datafilecopy '/rmanbak/oracle/oradata/NEROA/NEROA_TEST.dbf'; catalog datafilecopy '/rmanbak/oracle/oradata/OATEST.dbf'; catalog datafilecopy '/rmanbak/oracle/oradata/NEROA/oalinuxtest.dbf'; catalog datafilecopy '/rmanbak/oracle/oradata/NEROA/system02.dbf'; catalog datafilecopy '/rmanbak/oracle/oradata/NEROA/NEROA02.dbf'; catalog datafilecopy '/rmanbak/oracle/oradata/NEROA/sysaux02.dbf'; catalog datafilecopy '/rmanbak/oracle/oradata/NEROA/system03.dbf'; catalog datafilecopy '/rmanbak/oracle/oradata/NEROA/system04.dbf'; catalog datafilecopy '/rmanbak/oracle/oradata/NEROA/system05.dbf'; catalog datafilecopy '/rmanbak/oracle/oradata/NEROA/system06.dbf'; catalog datafilecopy '/rmanbak/oracle/oradata/NEROA/NEROA03.dbf'; catalog datafilecopy '/rmanbak/oracle/oradata/NEROA/system07.dbf'; catalog datafilecopy '/rmanbak/oracle/oradata/NEROA/system08.dbf'; catalog datafilecopy '/rmanbak/oracle/oradata/NEROA/system09.dbf'; catalog datafilecopy '/rmanbak/oracle/oradata/NEROA/NEROA04.dbf'; catalog datafilecopy '/rmanbak/oracle/oradata/NEROA/NEROA05.dbf';
2.5 切换至副本
switch datafile 1 to copy; switch datafile 2 to copy; switch datafile 3 to copy; switch datafile 4 to copy; switch datafile 5 to copy; switch datafile 6 to copy; switch datafile 7 to copy; switch datafile 8 to copy; switch datafile 9 to copy; switch datafile 10 to copy; switch datafile 11 to copy; switch datafile 12 to copy; switch datafile 13 to copy; switch datafile 14 to copy; switch datafile 15 to copy; switch datafile 16 to copy; switch datafile 17 to copy; switch datafile 18 to copy; switch datafile 19 to copy; switch datafile 20 to copy; switch datafile 21 to copy; --别问我为什么部switch database all ,问就是报错
2.6 由于源库有个数据文件状态为recover，需要将状态设置为offline。不然将从没有变化的scn号开始恢复
SQL> alter database datafile 4 offline;
2.7 手工recover，确认所需的归档（为什么要手工，因为rman报错，就是这么操蛋）
SQL> recover database using backup controlfile until cancel; --确定所需的归档
run{ allocate channel t1 type 'sbt_tape' parms 'ENV=(tdpo_optfile= /opt/tivoli/tsm/client/oracle/bin64/tdpo.opt)'; restore archivelog from logseq 14060; --从14060开始还原归档 release channel t1; }
SQL> recover database using backup controlfile until cancel; --应用已经还原的归档
2.8 重命名redo日志，因为路径不对
alter database rename file '/u01/oracle/oradata/NEROA/redo02.log' to '/rmanbak/oracle/oradata/NEROA/redo02.log'; alter database rename file '/u01/oracle/oradata/NEROA/redo01.log' to '/rmanbak/oracle/oradata/NEROA/redo01.log'; alter database rename file '/u01/oracle/oradata/NEROA/redo03.log' to '/rmanbak/oracle/oradata/NEROA/redo03.log';
2.9 open
SQL> alter database open resetlogs; alter database open resetlogs * 第 1 行出现错误: ORA-00392: 日志 3 (用于线程 1) 正被清除, 不允许操作 ORA-00312: 联机日志 3 线程 1: '/rmanbak/oracle/oradata/NEROA/redo03.log' SQL> alter database clear logfile group 1; 数据库已更改。 SQL> alter database clear logfile group 2; 数据库已更改。 SQL> alter database clear logfile group 3; SQL> alter database open resetlogs;
