12C RMAN 备份参考v1

windows bat

1,C:dbautility man man.bat

del C:dbautility manfull_db_* /q
set TNSNAME=ceipuat
rman target /@%TNSNAME% cmdfile=C:dbautility man man.cmd

2.C:dbautility man man.cmd

backup filesperset = 5 as compressed backupset database format 'C:dbautility manfull_db_%U' plus archivelog delete all input format 'C:dbautility manfull_db_arch_%U';

step 0:

backup scripts:

backup filesperset = 5 as compressed backupset database format 'C:dbautility manfull_db_%U' plus archivelog delete all input format 'C:dbautility manfull_db_arch_%U';

Step 1: 重启服务器后，oracle 会自动拉起，不需要操作。

检查健康方法：

确认以下服务的状态是正在运行的状态

OracleService****

OracleOraDB11gHome1TNSListener***

Step 2:

确定数据库文件的目录都存在（C:APPORACLEORADATAsidpdb_name or PDBSEED）

rman target /

restore controlfile from autobackup;

(或者指定的有控制文件备份的备份集)

alter database mount;

restore database;

restore arachivelog all;

recover database;

shutdown immediate;

startup mount;

alter database open resetlogs;

12C引进了pdb的概念,使得rman的恢复相对来说复杂了一些,这里对pdb的常规备份和恢复进行了简单测试,供大家参考

1.cdb启动和pdb关系测试

[oracle@xifenfei tmp]$ sqlplus / as sysdba

SQL*Plus: Release 12.1.0.0.2 Beta on Wed Dec 12 23:48:02 2012

3 2346805300 LX1 READ WRITE

4 2385557792 LX2 READ WRITE

5 1565384817 FF READ WRITE

证明直接startup cdb里面的pdb不会自动open,需要手工进行open

2.rman使用cdb备份数据库

RMAN-03002: failure of sql statement command at 12/12/2012 23:47:53

ORA-65046: operation not allowed from outside a pluggable database

--进入pdb库进行online

SQL> alter database datafile 19 online;

Database altered.

--验证数据

SQL> select count(*) from t_xifenfei;

COUNT(*)

----------

89604

试验证明:rman通过cdb级别操作,还是一步步恢复了pdb中离线异常的数据文件

8.pdb数据库冷备恢复

pdb数据库冷备恢复不需要完全关闭cdb数据库，只需要pdb数据库启动到mounted状态即可。

1.确保需要冷备的pdb1的open mode是mounted状态
SQL> show pdbs

CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
2 PDB$SEED READ ONLY NO
3 PDB READ WRITE NO
4 PDB1 MOUNTED

2.备份pdb1
[oracle@ora12c cdb]$ cp -r pdb1 pdb_bak
3.删除pdb1
[oracle@ora12c cdb]$ rm -rf pdb1
4.把pdb1数据库open
SQL> alter pluggable database pdb1 open;
alter pluggable database pdb1 open
*
ERROR at line 1:
ORA-01157: cannot identify/lock data file 44 - see DBWR trace file
ORA-01110: data file 44: '/u01/app/oracle/oradata/cdb/pdb1/pdb_users01.dbf'
5.利用冷备还原
[oracle@ora12c cdb]$ mv pdb_bak pdb1
6.重新把pdb1数据库open。
SQL> alter pluggable database pdb1 open;

Pluggable database altered.

SQL> show pdbs

CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
2 PDB$SEED READ ONLY NO
3 PDB READ WRITE NO
4 PDB1 READ WRITE NO
