我是靠谱客的博主高贵黑猫，最近开发中收集的这篇文章主要介绍未雨绸缪 - 一次数据库的TSM 完全恢复的实验记录，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

环境:AIX5.3ML03+Oracle 10.2.0.2+TSM 5.2

[@more@]

- RMAN 配置情况
注意:CONFIGURE CONTROLFILE AUTOBACKUP ON;

[testdb:oradev] /oradev1/home/rman> rman target /

Recovery Manager: Release 10.2.0.2.0 - Production on Tue May 22 12:54:50 2007

connected to target database: testdb (DBID=3996427334)

RMAN> show all;

using target database control file instead of recovery catalog
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/oradev1/app/oracle/product/10.2.0/dbs/s
napcf_testdb.f'; # default

- 备份脚本:

run {
allocate channel t1 type 'sbt_tape' parms 'ENV=(tdpo_optfile=/usr/tivoli/tsm/cli
ent/oracle/bin64/tdpo.opt)';
allocate channel t2 type 'sbt_tape' parms 'ENV=(tdpo_optfile=/usr/tivoli/tsm/cli
ent/oracle/bin64/tdpo.opt)';
backup incremental level 0 database format 'dbfull_%t_%s_%p' diskratio=0 databas
e include current controlfile;
sql 'alter system archive log current';
backup format 'arch%t_%s_%p' diskratio=0 archivelog all delete input;
release channel t1;
release channel t2;
}

- 创建新TABLESPACE 和USER T 以及新TABLE T ,并且插入数据, 这样的状态和备份前的状态完全不一样了

[testdb:oradev] /oradev1/home> sqlplus "/as sysdba"

SQL*Plus: Release 10.2.0.2.0 - Production on Tue May 22 11:44:41 2007

With the Partitioning, OLAP and Data Mining options

SQL> create tablespace t
2 datafile '/devtestdbdata/oradata/testdb/test01.dbf' size 5m;

Tablespace created.

SQL> create user t identified by test
2 default tablespace t;

User created.

SQL> grant connect,resource,dba to t;

Grant succeeded.

SQL>
SQL> conn t/test
Connected.
SQL>
SQL>
SQL> create table t (x int);

Table created.

SQL> begin
2 for i in 1 .. 300000
loop
3 4 insert into t values(i);
5 end loop;
6 end;
/ 7

PL/SQL procedure successfully completed.

SQL> SQL> commit;

Commit complete.

SQL> select count(*) from t;

COUNT(*)
----------
300000

- 切换一次日志, 以查看RECOVER ARCH的恢复情况
SQL> alter system switch logfile;

System altered.

SQL> quit

control01.ctl redo01.log sysaux01.dbf tem01.dbf users02.dbf
- 删掉TBSRMAN.dbf 文件,模拟故障出现
[testdb:oradev] /devtestdbdata/oradata/testdb> rm TBSRMAN.dbf

RMAN> quit

- 由于没有用到RMAN CATALOG 并且DB 在没启动状态,所以,RMAN 显示不可以用

[testdb:oradev] /devtestdbdata/oradata/testdb> sqlplus "/as sysdba"

- 现在执行如下恢复脚本
run {
allocate channel t1 type 'sbt_tape' parms 'ENV=(tdpo_optfile=/usr/tivoli/tsm/cli
ent/oracle/bin64/tdpo.opt)';
allocate channel t2 type 'sbt_tape' parms 'ENV=(tdpo_optfile=/usr/tivoli/tsm/cli
ent/oracle/bin64/tdpo.opt)';
restore database;
recover database;
sql'alter database open';
release channel t1;
release channel t2;
}
--会报错,说TEST01.DBF 在使用.不能创建,于是删掉TEST01.DBF ..模拟文件丢失
