记一次操蛋的rman恢复

Posted 2020-11-30 chhx

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;
