基于用户管理的备份与恢复－备份其它文件

备份归档日志

--查看第一个归档位置过去一天以来生成的归档日志,dest_id代表归档日志存放位置，对应到v$archive_dest中1～10的destination字段值，0代表不可用

SQL> select name from v$archived_log where dest_id=1 and first_time>=sysdate-1;

NAME
------------------------------------------------------------------------------------------------------------------------
/oracle/10g/oracle/log/archive_log/archive_1_23_757801926.arclog
/oracle/10g/oracle/log/archive_log/archive_1_24_757801926.arclog

SQL> select name from v$archived_log where dest_id=10 and first_time>=sysdate-1;

NAME
------------------------------------------------------------------------------------------------------------------------

SQL> select destination from v$archive_dest;

DESTINATION

--拷贝归档日志到指定的备份目录
cp

备份参数文件
1)如果使用文本参数文件(pfile)，使用OS命令拷贝到备份目录
2)如果使用spfile,使用create pfile 进行备份
3)如果使用pfile,使用create spfile进行备份
SQL> show parameter spfile

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
spfile string /oracle/10g/oracle/product/10.
2.0/db_1/dbs/spfileoralife.ora
--创建pfile，相当于备份spfile为pfile
SQL> create pfile = '/oracle/10g/oracle/bakup/database/pfileoralife.ora'
2 from spfile;

File created.

SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
--使用pfile启动数据库到nomount状态，也可以直接startup pfile='pfile全路径名'
SQL> startup nomount pfile='/oracle/10g/oracle/bakup/database/pfileoralife.ora';
ORACLE instance started.

Database altered.

SQL> shutdown immediate

--创建spfile到指定位置
SQL> create spfile='/oracle/10g/oracle/product/10.2.0/db_1/dbs/spfileoralife_test.ora' from
2 pfile='/oracle/10g/oracle/bakup/database/pfileoralife.ora';

File created.

SQL> shutdown immediate
ORA-01507: database not mounted
ORACLE instance shut down.
--数据库启动时不能指定spfile文件位置，但可以在pfile文件中引用spfile
SQL> startup nomount spfile='/oracle/10g/oracle/product/10.2.0/db_1/dbs/spfileoralife_test.ora'

--在pfileoralife.ora中添加
*.spfile='/oracle/10g/oracle/product/10.2.0/db_1/dbs/spfileoralife_test.ora'
使用pfile启动数据库
SQL> startup nomount pfile='/oracle/10g/oracle/bakup/database/pfileoralife.ora';
ORACLE instance started.

可以看出，已经使用了spfileoralife_test.ora。

备份口令文件
使用OS命令直接备份
