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

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

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
