Oracle冷备份脚本

一、原理

创新互联专业为企业提供旺苍网站建设、旺苍做网站、旺苍网站设计、旺苍网站制作等企业网站建设、网页设计与制作、旺苍企业网站模板建站服务，十多年旺苍做网站经验，不只是建网站，更提供有价值的思路和整体网络服务。

  1. 冷备份

    数据库在关闭状态下完成所有物理系统文件拷贝的过程，也称脱机备份

    适合于非归档模式下，数据库处于一致性状态

  1. 步骤

    首先在运行的库中得到数据库运行的所有的物理文件位置，然后在计划内关闭数据库(shutdown)

    再执行拷贝物理文家到备份路径或备份设备

    备份完成后立即启动数据库让其提供正常的服务

  2. 总结 - 优点

    冷备模式下概念易于理解，即将需要备份的文件复制到安全的位置

    操作比较简单，不需要太多的干预

    容易恢复到某个时间点上(只需将文件再拷贝回去)

    能与归档方法相结合，作数据库“最新状态”的恢复。

4.总结 - 缺点

备份时，数据库必须处于一致性关闭状态

只能提供到某一时间点的恢复

备份时速度比较慢，尤其是数据量大性能影响比较大

不能实现基于表和用户级别的数据恢复
二、案例

     首先应该在相关视图里查出数据库的数据文件，日志文件，控制文件，临时文件所在的位置。注意：不要直接把oradata下的cp就行了，因为生产库里各个文件通常分布在不同的磁盘，不同的地方，所以在去视图里获得真实路径 。

1).查看数据库是否为CDB
SYS@newtest>select name, decode(cdb, 'YES', 'Multitenant Option enabled', 'Regular 12c Database: ') "Multitenant Option" , open_mode, con_id from v$database;

NAME Multitenant Option OPEN_MODE CON_ID

NEWTEST Multitenant Option enabled READ WRITE 0
YES表示该数据库是CDB,如果是NO表示是NO-CDB(普通数据库)
2).查看实例和数据库的相关信息
SYS@newtest>select instance_name,version,status,archiver,database_status from v$instance;

INSTANCE_NAME VERSION STATUS ARCHIVE DATABASE_STATUS

newtest 12.2.0.1.0 OPEN STARTED ACTIVE
SYS@newtest>select dbid,name,log_mode from v$database;

  DBID NAME      LOG_MODE

1779551310 NEWTEST ARCHIVELOG
SYS@newtest>set linesize 180
SYS@newtest>col guid format A40
SYS@newtest>col name format A20
SYS@newtest>select con_id, dbid, guid, name , open_mode from v$pdbs;

CON_ID       DBID GUID                                     NAME                 OPEN_MODE
     2  603865257 32CAC9A05E614355926257BE671D9AFC         PDB$SEED             READ ONLY
     3 3394996704 24549D14BBEB417BAB312BF19BC5259E         PDBTEST              READ WRITE
     4   50957894 D4B2FCAAC2B944CC8AF5864EC7CB853C         CLONEPDB_PLUG        READ WRITE

3). 查看数据文件及状态信息

SYS@newtest>col file_name format A60
SYS@newtest>select file_name,tablespace_name,status,online_status from dba_data_files;

FILE_NAME TABLESPACENAME STATUS ONLINE

C:\APP\ADMINISTRATOR\VIRTUAL\ORADATA\NEWTEST\SYSTEM01.DBF SYSTEM AVAILABLE SYSTEM

SYS@newtest>col con_id format 99
SYS@newtest>col name format A80
SYS@newtest>select con_id,FILE#,NAME,status,enabled from v$datafile order by 1;

CON_ID FILE# NAME STATUS ENABLED

15 rows selected.
4).查看临时文件
SYS@newtest>col name format A100
SYS@newtest>select name from v$tempfile;

NAME

C:\APP\ADMINISTRATOR\VIRTUAL\ORADATA\NEWTEST\TEMP01.DBF
C:\APP\ADMINISTRATOR\VIRTUAL\ORADATA\NEWTEST\PDBSEED\TEMP012017-12-13_17-23-31-944-PM.DBF
C:\APP\ADMINISTRATOR\VIRTUAL\ORADATA\NEWTEST\PDBTEST\TEMP012017-12-13_17-23-31-944-PM.DBF
C:\APP\ADMINISTRATOR\VIRTUAL\ORADATA\NEWTEST\CLONEPDB_PLUG\TEMP012017-12-13_17-23-31-944-PM.DBF

5).查看日志文件
SYS@newtest>col member format A60
SYS@newtest>select member from v$logfile;

MEMBER

C:\APP\ADMINISTRATOR\VIRTUAL\ORADATA\NEWTEST\REDO03.LOG
C:\APP\ADMINISTRATOR\VIRTUAL\ORADATA\NEWTEST\REDO02.LOG
C:\APP\ADMINISTRATOR\VIRTUAL\ORADATA\NEWTEST\REDO01.LOG
6).查看控制文件
SYS@newtest>select name from v$controlfile;

NAME

C:\APP\ADMINISTRATOR\VIRTUAL\ORADATA\NEWTEST\CONTROL01.CTL
C:\APP\ADMINISTRATOR\VIRTUAL\ORADATA\NEWTEST\CONTROL02.CTL
7).创建备份目录
SYS@newtest>ho mkdir c:\oracleback
SYS@newtest>select 'ho mkdir '|| ' &dir\' ||NAME from v$pdbs;
Enter value for dir: C:\oracleback
old 1: select 'ho mkdir '|| ' &dir\' ||NAME from v$pdbs
new 1: select 'ho mkdir '|| ' C:\oracleback\' ||NAME from v$pdbs

'HOMKDIR'||'C:\ORACLEBACK\'||NAME

ho mkdir C:\oracleback\PDB$SEED
ho mkdir C:\oracleback\PDBTEST
ho mkdir C:\oracleback\CLONEPDB_PLUG
8).使用连接符生成复制文件命令
SYS@newtest>select 'ho copy ' || name || ' &dir' from v$controlfile
2 union all
3 select 'ho copy ' || member || ' &dir' from v$logfile
4 union all
5 select 'ho copy ' || file_name|| ' &dir' from dba_data_files
6 union all
7 select 'ho copy ' || vd.name || ' &dir\'|| vp.name as command from v$datafile vd join v$pdbs vp using(con_id)
8 union all
9 select 'ho copy ' || vt.name || ' &dir\'|| vp.name as command from v$tempfile vt join v$pdbs vp using(con_id)
10 /
Enter value for dir: C:\oracleback
old 1: select 'ho copy ' || name || ' &dir' from v$controlfile
new 1: select 'ho copy ' || name || ' C:\oracleback' from v$controlfile
Enter value for dir: C:\oracleback
old 3: select 'ho copy ' || member || ' &dir' from v$logfile
new 3: select 'ho copy ' || member || ' C:\oracleback' from v$logfile
Enter value for dir: C:\oracleback
old 5: select 'ho copy ' || file_name|| ' &dir' from dba_data_files
new 5: select 'ho copy ' || file_name|| ' C:\oracleback' from dba_data_files
Enter value for dir: C:\oracleback
old 7: select 'ho copy ' || vd.name || ' &dir\'|| vp.name as command from v$datafile vd join v$pdbs vp using(con_id)
new 7: select 'ho copy ' || vd.name || ' C:\oracleback\'|| vp.name as command from v$datafile vd join v$pdbs vp using(con_id)
Enter value for dir: C:\oracleback
old 9: select 'ho copy ' || vt.name || ' &dir\'|| vp.name as command from v$tempfile vt join v$pdbs vp using(con_id)
new 9: select 'ho copy ' || vt.name || ' C:\oracleback\'|| vp.name as command from v$tempfile vt join v$pdbs vp using(con_id)
