1、數(shù)據(jù)庫(kù)環(huán)境
數(shù)據(jù)庫(kù)DBID及打開模式
SQL> select dbid,open_mode from v$database; DBID OPEN_MODE ---------- ---------- 4106451204 READ WRITE
數(shù)據(jù)文件:
SQL> select file#,status,enabled,name from v$datafile; FILE# STATUS ENABLED NAME ---------- ------- ---------- -------------------------------------------------------------------------------- 1 SYSTEM READ WRITE /u01/app/oracle/oradata/ocmdb/dfile/system01.dbf 2 ONLINE READ WRITE /u01/app/oracle/oradata/ocmdb/undotbs01.dbf 3 ONLINE READ WRITE /u01/app/oracle/oradata/ocmdb/dfile/sysaux01.dbf 4 ONLINE READ WRITE /u01/app/oracle/oradata/ocmdb/dfile/tbs_1.dbf 5 ONLINE READ WRITE /u01/app/oracle/oradata/ocmdb/dfile/tbs3.dbf 6 ONLINE READ WRITE /u01/app/oracle/oradata/ocmdb/dfile/tbs_big01.dbf 7 ONLINE READ WRITE /u01/app/oracle/oradata/ocmdb/dfile/rman.dbf
控制文件：
SQL> select status,name from v$controlfile; STATUS NAME ------- -------------------------------------------------------------------------------- /u01/app/oracle/ocmdb/cfile/ora_control1 /u01/app/oracle/ocmdb/cfile/ora_control2 /u01/app/oracle/ocmdb/cfile/control3
聯(lián)機(jī)日志：
SQL> select group#,status,type,member from v$logfile; GROUP# STATUS TYPE MEMBER ---------- ------- ------- -------------------------------------------------------------------------------- 1 ONLINE /u01/app/oracle/oradata/ocmdb/lfile/redo01.log 1 ONLINE /u01/app/oracle/oradata/ocmdb/lfile/redo11.log 3 ONLINE /u01/app/oracle/oradata/ocmdb/lfile/redo03.log 2 ONLINE /u01/app/oracle/oradata/ocmdb/lfile/redo02.log 5 ONLINE /u01/app/oracle/oradata/ocmdb/lfile/redo05.log 5 ONLINE /u01/app/oracle/oradata/ocmdb/lfile/redo55.log 4 ONLINE /u01/app/oracle/oradata/ocmdb/lfile/redo04.log 4 ONLINE /u01/app/oracle/oradata/ocmdb/lfile/redo44.log
2、數(shù)據(jù)庫(kù)備份腳本
冷備份腳本
#rem script:coldbak.sh #rem creater:chon #rem date:2011 #rem desc:offline full backup database #--connect database sqlplus / as sysdba EOF #--shutdown database shutdown immediate; #--Copy Data file !cp /u01/app/oracle/oradata/ocmdb/dfile/*.dbf /backup !cp /u01/app/oracle/oradata/ocmdb/undotbs01.dbf /backup #--Copy Control file !cp /u01/app/oracle/ocmdb/cfile/* /backup #--Copy Log file !cp /u01/app/oracle/oradata/ocmdb/lfile/*.log /backup #--Copy archive log !cp -R /u01/app/oracle/rmanbak/OCMDB/archivelog/* /backup #--startup database startup;
說明：
1、以上腳本在數(shù)據(jù)庫(kù)關(guān)閉狀態(tài)下備份數(shù)據(jù)庫(kù)所有的數(shù)據(jù)文件，聯(lián)機(jī)日志，控制文件，歸檔日志（在一個(gè)目錄下），如果成功備份，所有文件是一致的。
2、沒有備份參數(shù)文件，參數(shù)文件可以另外備份，沒有必要每次都備份，只需要在改變?cè)O(shè)置后備份一次。
3、如果以上命令沒有成功依次執(zhí)行，那么備份將是無(wú)效的，如連接數(shù)據(jù)庫(kù)不成功，那么肯定關(guān)閉數(shù)據(jù)庫(kù)也不成功，那么備份則無(wú)效
4、冷備份建議下人工干預(yù)下執(zhí)行。

OS熱備份
查看表空間和數(shù)據(jù)文件對(duì)應(yīng)關(guān)系
SQL> select file_id,tablespace_name,file_name from dba_data_files; FILE_ID TABLESPACE_NAME FILE_NAME ---------- ------------------------------ -------------------------------------------------------------------------------- 7 RMAN_TS /u01/app/oracle/oradata/ocmdb/dfile/rman.dbf 6 BIG_TBS /u01/app/oracle/oradata/ocmdb/dfile/tbs_big01.dbf 5 TBS3 /u01/app/oracle/oradata/ocmdb/dfile/tbs3.dbf 4 TBS_1 /u01/app/oracle/oradata/ocmdb/dfile/tbs_1.dbf 3 SYSAUX /u01/app/oracle/oradata/ocmdb/dfile/sysaux01.dbf 2 UNDOTBS /u01/app/oracle/oradata/ocmdb/undotbs01.dbf 1 SYSTEM /u01/app/oracle/oradata/ocmdb/dfile/system01.dbf
數(shù)據(jù)庫(kù)OS熱全備份腳本
#rem script:hotbak.sh #rem creater:chon #rem date:2011 #rem desc:backup all database datafile in archive #--connect database sqlplus / as sysdba EOF #--archive alter system archive log current; #--start hotbak alter tablespace system begin backup; !cp /u01/app/oracle/oradata/ocmdb/dfile/system01.dbf /backup alter tablespace system end backup; alter tablespace UNDOTBS begin backup; !cp /u01/app/oracle/oradata/ocmdb/undotbs01.dbf /backup alter tablespace UNDOTBS end backup; alter tablespace SYSAUX begin backup; !cp /u01/app/oracle/oradata/ocmdb/dfile/sysaux01.dbf /backup alter tablespace SYSAUX end backup; alter tablespace TBS_1 begin backup; !cp /u01/app/oracle/oradata/ocmdb/dfile/tbs_1.dbf /backup alter tablespace TBS_1 end backup; alter tablespace TBS3 begin backup; !cp /u01/app/oracle/oradata/ocmdb/dfile/tbs3.dbf /backup alter tablespace TBS3 end backup; alter tablespace BIG_TBS begin backup; !cp /u01/app/oracle/oradata/ocmdb/dfile/tbs_big01.dbf /backup alter tablespace BIG_TBS end backup; alter tablespace RMAN_TS begin backup; !cp /u01/app/oracle/oradata/ocmdb/dfile/rman.dbf /backup alter tablespace RMAN_TS end backup; #--end #--bak control file #--binary alter database backup controlfile to '/backup/controlbinbak.000'; #--ascii alter database backup controlfile to trace; alter system archive log current;
說明：
1、熱備份必須在數(shù)據(jù)庫(kù)歸檔方式下才可以運(yùn)行
2、以上腳本可以在數(shù)據(jù)庫(kù)運(yùn)行狀態(tài)下備份數(shù)據(jù)庫(kù)所有的數(shù)據(jù)文件（除了臨時(shí)數(shù)據(jù)文件），沒有必要備份聯(lián)機(jī)日志。
3、歸檔日志至少需要一次完整備份之后的所有日志。
4、如果以上命令沒有成功依次執(zhí)行，那么備份也是無(wú)效的，如連接數(shù)據(jù)庫(kù)不成功，那么備份則無(wú)效
