我要评论1、数据库环境
数据库dbid及打开模式
sql> select dbid,open_mode from v$database; dbid open_mode ---------- ---------- 4106451204 read write
数据文件:
sql> select file#,status,enabled,name from v$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$controlfile; status name ------- -------------------------------------------------------------------------------- /u01/app/oracle/ocmdb/cfile/ora_control1 /u01/app/oracle/ocmdb/cfile/ora_control2 /u01/app/oracle/ocmdb/cfile/control3
联机日志：
sql> select group#,status,type,member from v$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、数据库备份脚本
冷备份脚本
#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;
说明：
1、以上脚本在数据库关闭状态下备份数据库所有的数据文件，联机日志，控制文件，归档日志（在一个目录下），如果成功备份，所有文件是一致的。
2、没有备份参数文件，参数文件可以另外备份，没有必要每次都备份，只需要在改变设置后备份一次。
3、如果以上命令没有成功依次执行，那么备份将是无效的，如连接数据库不成功，那么肯定关闭数据库也不成功，那么备份则无效
4、冷备份建议下人工干预下执行。

os热备份
查看表空间和数据文件对应关系
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
数据库os热全备份脚本
#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;
说明：
1、热备份必须在数据库归档方式下才可以运行
2、以上脚本可以在数据库运行状态下备份数据库所有的数据文件（除了临时数据文件），没有必要备份联机日志。
3、归档日志至少需要一次完整备份之后的所有日志。
4、如果以上命令没有成功依次执行，那么备份也是无效的，如连接数据库不成功，那么备份则无效

一周差异备份策略：
备份目标库和catalog库
周日0级全备，周一周二为2级，周三为1级，周四周五周六为2级。
每天凌晨1点10分开始备份
零级备份
backup incremental level 0 database;
一级差异增量 差异增量是默认增量备份方式
backup incremental level 1 database;
一级累计增量
backup incremental level 1 cumulative database;
