如下Linux环境下对Oracle单节点数据库采用文件系统情况的配置归档模式过程。首先查看数据库归档模式和磁盘使用情况，确定归档文件放到什么位置：

 
 

  
  
[oracle@gisdbserver~]$sqlplus/assysdba
  
  
sql>archiveloglist
  
  
DatabaselogmodeNoArchiveMode
  
  
AutomaticarchivalDisabled
  
  
Archivedestination/dbback/archivelog
  
  
Oldestonlinelogsequence92
  
  
Currentlogsequence97
 
 

根据如下磁盘使用情况，在相应的目录下建立相关归档和备份目录：

  
  
[root@gisdbserver~]#df-h
  
  
FilesystemSizeUsedAvailUse%Mountedon
  
  
/dev/mapper/vg_gisdbserver-lv_root99G3.8G90G4%/
  
  
tmpfs16G76K16G1%/dev/shm
  
  
/dev/sda2485M39M421M9%/boot
  
  
/dev/sda1200M260K200M1%/boot/efi
  
  
/dev/mapper/vg_gisdbserver-LogVol03481G198M457G1%/dbback
  
  
/dev/mapper/vg_gisdbserver-LogVol04407G9.3G377G3%/home
  
  
/dev/mapper/vg_gisdbserver-LogVol0299G4.5G89G5%/opt
  
  
dev/sdb441G72G347G18%/oradata
 
 

创建相关归档日志存放目录：

  
  
[root@gisdbserver~]#cd/dbback/
  
  
[root@gisdbserverdbback]#mkdirarchivelog
  
  
[root@gisdbserverdbback]#chown-Roracle:oinstallarchivelog/
  
  
[root@gisdbserverdbback]#mkdirrman
  
  
[root@gisdbserverdbback]#chownoracle:oinstallrman/
  
  
[root@gisdbserverrman]#mkdirfullback
  
  
[root@gisdbserverrman]#mkdirarchiveback
  
  
[root@gisdbserverrman]#chownoracle:oinstallarchiveback/
  
  
[root@gisdbserverrman]#chownoracle:oinstallfullback/
 
 

登录数据库指定归档存放目录：

assysdba
  
  
sql>altersystemsetlog_archive_dest_1='location=/dbback/archivelog';
  
  
Systemaltered.
  
  
sql>showparameterlog_archive_dest_1
  
  
NAMETYPEVALUE
  
  
-----------------------------------------------------------------------------
  
  
log_archive_dest_1stringlocation=/dbback/archivelog
 
 

要将非归档数据库模式改为归档模式，需要在mount状态下执行alter database archivelog命令才行，如下：

  
  
sql>archiveloglist
  
  
NoArchiveMode
  
  
AutomaticarchivalDisabled
  
  
Archivedestination/dbback/archivelog
  
  
Oldestonlinelogsequence92
  
  
sequence97
  
  
sql>alterdatabasearchivelog;
  
  
databasearchivelog
  
  
*
  
  
ERRORatline1:
  
  
ORA-01126:databasemustbemountedinthisinstanceandnotopeninany
  
  
instance
 
 

因此需要在合适的时间关闭数据库，重新启动到mount状态下才能改变为归档模式。

  
  
sql>shutdownimmediate;
  
  
sql>startupmount;
  
  
sql>databasearchivelog;
 
 

要开启rman备份，需要对配置rman相关的一些参数，具体如下：

  
  
oracle@gisdbserver~]$rmantarget/
  
  
RMAN>backupDATABASEincludeCURRENTcontrolfileformat'/dbback/rman/fullback/data_%d_%T_%s_%p'plusarchivelogformat'+/dbback/rman/archiveback/arch_%d_%T_%s';
 
 

以上语句也可以通过linux的crontab 和 bash脚本方式进行自动化运行。

  
  
run{
  
  
DELETENOPROMPTexpiredarchivelogALL;
  
  
allocatechanneld1TYPEdiskmaxpiecesize=30G;
  
  
allocatechanneld2TYPEdiskmaxpiecesize=30G;
  
  
backupCURRENTcontrolfileformat'/dbback/rman/fullback/data_%d_%T_%s_%p'plusarchivelogformat'+/dbback/rman/archiveback/arch_%d_%T_%s';
  
  
releasechanneld1;
  
  
releasechanneld2;
  
  
crosscheckbackup;
  
  
DELETEnopromptobsoleteREDUNDANCY1;
  
  
}
