• 完整的oraclerman备份恢复的例子


    1、 建rman库作为repository
      $more createrman_db1.sh
      set echo on
      spool makedb1.log
      create database rman
      datafile '/export/home/oracle/oradata/rman_data/system.dbf' size 50m autoextend
      on next 640K
      logfile '/export/home/oracle/oradata/rman_data/redo0101.log' SIZE 10M,
      '/export/home/oracle/oradata/rman_data/redo0201.log' SIZE 10M
      maxdatafiles 30
      maxinstances 8
      maxlogfiles 64
      character set US7ASCII
      national character set US7ASCII
      ;
      disconnect
      spool off
      exit
      @/export/home/oracle/8.1.6/rdbms/admin/catalog.sql;
      REM ********** ALTER SYSTEM TABLESPACE *********
      ALTER TABLESPACE SYSTEM
      DEFAULT STORAGE ( INITIAL 64K NEXT 64K MINEXTENTS 1 MAXEXTENTS UNLIMITED PCTINCR
      EASE 50);
      ALTER TABLESPACE SYSTEM
      MINIMUM EXTENT 64K;
      REM ********** TABLESPACE FOR ROLLBACK **********
      CREATE TABLESPACE RBS DATAFILE '/export/home/oracle/oradata/rman_data/rbs.dbf' s
      ize 50m
      AUTOEXTEND ON NEXT 512K
      MINIMUM EXTENT 512K
      DEFAULT STORAGE ( INITIAL 512K NEXT 512K MINEXTENTS 10 MAXEXTENTS UNLIMITED PC
      TINCREASE 0 );
      REM ********** TABLESPACE FOR TEMPORARY **********
      CREATE TABLESPACE TEMP DATAFILE '/export/home/oracle/oradata/rman_data/temp.dbf'
      size 50m
      AUTOEXTEND ON NEXT 64K
      MINIMUM EXTENT 64K
      DEFAULT STORAGE ( INITIAL 64K NEXT 64K MINEXTENTS 1 MAXEXTENTS UNLIMITED PCTINCR
      EASE 0) TEMPORARY;
      REM **** Creating four rollback segments ****************
      CREATE PUBLIC ROLLBACK SEGMENT RBS_0 TABLESPACE RBS
      STORAGE ( OPTIMAL 64000K );
      ALTER ROLLBACK SEGMENT "RBS_0" ONLINE;
      REM **** SYS and SYSTEM users ****************
      alter user sys temporary tablespace TEMP;
      alter user system temporary tablespace TEMP;
      disconnect
      spool off
      exit
      $more createrman_db3.sh
      spool crdb3.log
      @/export/home/oracle/8.1.6/rdbms/admin/catproc.sql
      @/export/home/oracle/8.1.6/rdbms/admin/caths.sql
      @/export/home/oracle/8.1.6/rdbms/admin/otrcsvr.sql
      connect system/manager
      @/export/home/oracle/8.1.6/sqlplus/admin/pupbld.sql
      disconnect
      spool off
      exit
      2、建repository存放的表空间和rman用户
      $more createrman_db4.sh
      connect internal
      create tablespace rman_ts
      datafile '/export/home/oracle/oradata/rman_data/rman_ts.dbf'
      size 20M default storage (initial 100K next 100K pctincrease 0);
      create user rman_hainan identified by rman_hainan
      temporary tablespace TEMP
      default tablespace rman_ts quota unlimited on
      rman_ts;
      grant recovery_catalog_owner to rman_hainan;
      grant connect ,resource to rman_hainan;
      3、建catalog,注册目标数据库
      $more createrman_db5.sh
      rman catalog rman_hainan/rman_hainan@rman msglog=rman.log
      create catalog ;
      exit;
      rman target sys/oracle@db1
      connect catalog rman_hainan/rman_hainan@rman
      register database;
      exit;
      4、可以开始做备份了。
      5、做全备
      $more rmanshell
      . /export/home/oracle/.profile
      rman rcvcat rman_hainan/rman_hainan@rman target / cmdfile /export/home/oracle/ba
      ckup_level0.rcv log /export/home/oracle/backup.log
      $more backup_level0.rcv
      resync catalog;
      run {
      allocate channel t1 type disk;
      backup
      incremental level 0
      skip inaccessible
      tag hot_db_bk_level0
      filesperset 3
      format '/export/home/oracle/bk_%s_%p_%t.bk'
      (database);
      sql 'alter system archive log current';
      backup
      filesperset 10
      format '/export/home/oracle/a1_%s_%p_%t.ac'
      (archivelog all delete input);
      backup
      format '/export/home/oracle/df_t%t_s%s_p%p.ct'
      current controlfile ;
      }
      6、做增备
      $more rmanshell1
      rman rcvcat rman_hainan/rman_hainan@rman target / cmdfile backup_level1.rcv log
      backup.log
      $more backup_level1.rcv
      resync catalog;
      run {
      allocate channel t1 type disk;
      backup
      incremental level 1
      skip inaccessible
      tag hot_db_bk_level1
      filesperset 3
      format 'bk_%s_%p_%t.bk1'
      (database);
      sql 'alter system archive log current';
      backup
      filesperset 10
      format 'a1_%s_%p_%t.ac1'
      (archivelog all delete input);
      backup current controlfile;
      }
      1、 删除旧的全备
      $rman rcvcat rman_hainan/rman_hainan@rman target /
      Recovery Manager: Release 8.1.6.0.0 - Production
      RMAN-06005: connected to target database: TEST (DBID=1692992254)
      RMAN-06008: connected to recovery catalog database
      RMAN list backupset;
      RMAN-03022: compiling command: list
      List of Backup Sets
      Key Recid Stamp LV Set Stamp Set Count Completion Time
      ------- ---------- ---------- -- ---------- ---------- ----------------------
      38 145 399987408 0 399987406 153 11-JUN-00
      根据key来删除旧的备份。
      RMAN allocate channel for maintenance type disk;
      RMAN change backupset 169 delete; ----------THIS IS THE COMMAND TO REMOVE THE ENTRY & OS FILE
      做完后可以看到list backupset和操作系统的文件都没有了。
      2、 恢复
      (1) 将数据库启动到nomount状态:
      $svrmgrl
      Oracle Server Manager Release 3.1.6.0.0 - Production
      Copyright (c) 1997, 1999, Oracle Corporation. All Rights Reserved.
      Oracle8i Enterprise Edition Release 8.1.6.0.0 - 64bit Production
      With the Partitioning option
      JServer Release 8.1.6.0.0 - Production
      SVRMGR connect internal
      Connected.
      SVRMGR startup nomount;
      ORACLE instance started.
      Total System Global Area 339275684 bytes
      Fixed Size 94116 bytes
      Variable Size 318685184 bytes
      Database Buffers 16384000 bytes
      Redo Buffers 4112384 bytes
      SVRMGR exit
      Server Manager complete.
      (2) 恢复控制文件:
      $rman rcvcat rman_hainan/rman_hainan@rman target /
      Recovery Manager: Release 8.1.6.0.0 - Production
      RMAN-06006: connected to target database: test (not mounted)
      RMAN-06008: connected to recovery catalog database
      RMAN run {
      2 allocate channel d1 type disk;
      3 restore controlfile;
      4 release channel d1;
      5 }
      (3) 恢复数据文件
      RMAN run {
      2 allocate channel d1 type disk;
      3 sql "alter database mount";
      4 restore datafile 1;
      5 restore datafile 2;
      6 restore datafile 3;
      7 restore datafile 4;
      8 release channel d1;
      9 }
      (4) 恢复日志文件
      RMAN run {
      2 set archivelog destination to '/export/home/oracle/admin/test/arch';
      3 allocate channel d1 type disk;
      4 restore archivelog all;
      5 release channel d1;
      6 }
      会把所有的日志文件恢复。
      (5) 根据日志做recover
      $svrmgrl
      Oracle Server Manager Release 3.1.6.0.0 - Production
      Copyright (c) 1997, 1999, Oracle Corporation. All Rights Reserved.
      Oracle8i Enterprise Edition Release 8.1.6.0.0 - 64bit Production
      With the Partitioning option
      JServer Release 8.1.6.0.0 - Production
      SVRMGR connect internal
      Connected.
      SVRMGR recover database using backup controlfile until cancel;
      ORA-00279: change 51054 generated at 06/11/2000 11:38:37 needed for thread 1
      ORA-00289: suggestion : /export/home/oracle/admin/test
