oracle数据库全备份和增量备份

..优选1.检查数据库模式：sqlplus/nologconn/assysdbaarchiveloglist(查看数据库是否处于归档模式中)假设为非归档,那么修改数据库归档模式。startupmountalterdatabasearchivelogalterdatabaseopen2.连接到target数据库命令：connecttarget/(connecttargetsystem/oracleora10g,如果数据库没有起来，也可要直接在rman命令下用startup进展启动数据库)可以连接到targetdatabase.(rman一边连接到target数据库，另外一边连接到controlfile(nocatalogmode),controlfile中存储rman的备份信息)3.用listbackupset命令查看有没有备份4.常用备份命令：备份全库：RMAN>backupdatabaseplusarchivelogdeleteinput;(备份全库及控制文件、效劳器参数文件与所有归档的重做日志，并删除旧的归档日志)备份 表 关于同志近三年现实表现材料材料类招标技术评分表图表与交易pdf视力表打印pdf用图表说话 pdf 空间：RMAN>backuptablespacesystemplusarchivelogdeleteinput;(备份指定表空间及归档的重做日志，并删除旧的归档日志)_备份归档日志：RMAN>backuparchivelogalldeleteinput;全库备份〔备份数据文件中有数据的，有数据文件，控制文件，归档日志文件，spfile文件，不备份联机重做日志文件或临时文件〕RMAN>CONFIGURECONTROLFILEAUTOBACKUPON;--控制文件自动备份RMAN>CONFIGUREDEVICETYPEDISKPARALLELISM2backuptypetopressedbackupset;--压缩RMAN>CONFIGUREchannelDEVICETYPEDISKformat'D:\APP\rman\full_%s.bk';--备份的路径RMAN>BACKUPDATABASE;--全备份RMAN>listbackupofdatabase;--检查备份信息RMAN>backuparchivelogalldeleteinput;--备份归档日志并删除归档日志RMAN>listbackupofarchivelogall;--检查归档日志差异增量备份RMAN>backupincrementallevel0database;--0级全备份RMAN>backupincrementallevel2database;--2级备份RMAN>listbackupofdatabase;--检查备份信息累积增量备份〔2c不做参照对象〕RMAN>backupincrementallevel2cumulativedatabase;中心数据库,RMAN一周备份方案============================0.星期天晚上-level0backupperformed(全备份)1.星期一晚上-level2backupperformed2.星期二晚上-level2backupperformed3.星期三晚上-level1backupperformed4.星期四晚上-level2backupperformed5.星期五晚上-level2backupperformed6.星期六晚上-level2backupperformed如果星期二需要恢复的话，只需要0+1,如果星期四需要恢复的话，只需要0+3,如果星期五需要恢复的话，只需要0+3+4,如果星期六需要恢复的话，只需要0+3+4+5具体步骤：创立0,1,2级备份脚本D:\rman_bak_scriptrun{allocatechannelc1typedisk;allocatechannelc2typedisk;allocatechannelc3typedisk;backupaspressedbackupsetincrementallevel0tag'db_level0'databaseformat'H:\RMAN_BAK\level0_%u_%s_%p.bak';sql'altersystemarchivelogcurrent';backupaspressedbackupsetarchivelogallformat'H:\ARCHIVELOG_BAK\arch0_%u_%s_%p'deleteinput;deletenopromptobsolete;releasechannelc1;releasechannelc2;releasechannelc3;}run{allocatechannelc1typedisk;allocatechannelc2typedisk;allocatechannelc3typedisk;backupaspressedbackupsetincrementallevel1tag'db_level1'databaseformat'H:\RMAN_BAK\level1_%u_%s_%p.bak';sql'altersystemarchivelogcurrent';backupaspressedbackupsetarchivelogallformat'H:\ARCHIVELOG_BAK\arch1_%u_%s_%p'deleteinput;deletenopromptobsolete;releasechannelc1;releasechannelc2;releasechannelc3;}run{allocatechannelc1typedisk;allocatechannelc2typedisk;allocatechannelc3typedisk;backupaspressedbackupsetincrementallevel2tag'db_level2'databaseformat'H:\RMAN_BAK\level2_%u_%s_%p.bak';sql'altersystemarchivelogcurrent';backupaspressedbackupsetarchivelogallformat'H:\ARCHIVELOG_BAK\arch2_%u_%s_%p'deleteinput;deletenopromptobsolete;releasechannelc1;releasechannelc2;releasechannelc3;}创立周日至周六执行的批处理文件D:\rman_bak_script\Mon…Sun星期天rmantarget/logD:\rman_bak_script\Sun\rmanlog_Sun%date:~0,4%_%date:~5,2%_%date:~8,2%.txtcmdfile=D:\rman_bak_script\rman_level0d星期一rmantarget/logD:\rman_bak_script\Mon\rmanlog_Mon%date:~0,4%_%date:~5,2%_%date:~8,2%.txtcmdfile=D:\rman_bak_script\rman_level2d星期二rmantarget/logD:\rman_bak_script\Tue\rmanlog_Tue%date:~0,4%_%date:~5,2%_%date:~8,2%.txtcmdfile=D:\rman_bak_script\rman_level2d星期三rmantarget/logD:\rman_bak_script\Wen\rmanlog_Wen%date:~0,4%_%date:~5,2%_%date:~8,2%.txtcmdfile=D:\rman_bak_script\rman_level1d星期四rmantarget/logD:\rman_bak_script\Thu\rmanlog_Thu%date:~0,4%_%date:~5,2%_%date:~8,2%.txtcmdfile=D:\rman_bak_script\rman_level2d星期五rmantarget/logD:\rman_bak_script\Fri\rmanlog_Fri%date:~0,4%_%date:~5,2%_%date:~8,2%.txtcmdfile=D:\rman_bak_script\rman_level2d星期六rmantarget/logD:\rman_bak_script\Sat\rmanlog_Sat%date:~0,4%_%date:~5,2%_%date:~8,2%.txtcmdfile=D:\rman_bak_script\rman_level2d创立任务方案
