如下Linux环境下对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 / as sysdba

SQL> archive log

list

Database log

modeNo Archive Mode

Automatic

archivalDisabled

Archive

destination/dbback/archivelog

Oldest online log

sequence92

Current log

sequence97

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

FilesystemSizeUsed Avail Use% Mounted on

/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@gisdbserver

dbback]# mkdir archivelog

[root@gisdbserver

dbback]# chown -R oracle:oinstall archivelog/

[root@gisdbserver

dbback]# mkdir rman

[root@gisdbserver

dbback]# chown oracle:oinstall rman/

[root@gisdbserver

rman]# mkdir fullback

[root@gisdbserver

rman]# mkdir archiveback

[root@gisdbserver

rman]# chown oracle:oinstall archiveback/

[root@gisdbserver

rman]# chown oracle:oinstall fullback/

登录数据库指定归档存放目录：

[oracle@gisdbserver

~]$ sqlplus / as sysdba

SQL> alter system

set log_archive_dest_1='location=/dbback/archivelog';

System altered.

SQL> show

parameter log_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> archive log

list

Database log

modeNo Archive Mode

Automatic

archivalDisabled

Archive

destination/dbback/archivelog

Oldest online log

sequence92

Current log

sequence97

SQL> alter

database archivelog;

alter database

archivelog

*

ERROR at line 1:

ORA-01126: database

must be mounted in this instance and not open in any

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>shutdown immediate;

SQL>startup mount;

SQL> alter

database archivelog;

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

~]$ rman target /

RMAN>

backup DATABASE include CURRENT controlfile format '/dbback/rman/fullback/data_%d_%T_%s_%p' plus

archivelog format '+/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{

DELETE NOPROMPT expired archivelog ALL;

allocate channel d1 TYPE disk

maxpiecesize=30G;

allocate channel d2 TYPE disk

maxpiecesize=30G;

backup DATABASE

include CURRENT controlfile format '/dbback/rman/fullback/data_%d_%T_%s_%p' plus archivelogformat '+/dbback/rman/archiveback/arch_%d_%T_%s';

release channel d1;

release channel d2;

crosscheck backup;

DELETE noprompt obsolete REDUNDANCY 1;

}
