12cR1 PDB只读与读写转换

PDB只读与读写转换

1、pdb 到mount状态
sql> alter pluggable database pdb11 close immediate;

Pluggable database altered.
2、查看pdb
sql> show pdbs;

    CON_ID CON_NAME                       OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------
         2 PDB$SEED                       READ ONLY  NO
         3 PDB11                          MOUNTED
sql> 
3、pdb只读
sql> 
sql> alter pluggable database pdb11 open read only;

Pluggable database altered.

sql> show pdbs;

    CON_ID CON_NAME                       OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------
         2 PDB$SEED                       READ ONLY  NO
         3 PDB11                          READ ONLY  NO
sql> alter pluggable database pdb11 close immediate;

Pluggable database altered.

4、pdb读写
sql> alter pluggable database pdb11 open read write;

Pluggable database altered.

sql> show pdbs;

    CON_ID CON_NAME                       OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------
         2 PDB$SEED                       READ ONLY  NO
         3 PDB11                          READ WRITE NO
