測試重建pdb的xml文件

查看pdb

SQL> show pdbs

    CON_ID CON_NAME                       OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------
         2 PDB$SEED                       READ ONLY  NO
         3 PDB11G                         READ WRITE NO

關閉pdb11g

SQL> alter pluggable database PDB11G close instances=all;

Pluggable database altered.

拔出pdb

SQL> alter pluggable database pdb11g unplug into '/home/oracle/pdb11g.xml';

Pluggable database altered.

刪除pdb11g

SQL> drop pluggable database pdb11g;

Pluggable database dropped.

SQL> show pdbs

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

執行DBMS_PDB.RECOVER重新生成xml

使用新的xml插入pdb

SQL> create pluggable database pdb11g using '/home/oracle/test.xml';

Pluggable database created.

SQL> show pdbs

    CON_ID CON_NAME                       OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------
         2 PDB$SEED                       READ ONLY  NO
         3 PDB11G                         MOUNTED

啓動數據庫

SQL>  alter pluggable database PDB11G open instances=all;

Pluggable database altered.

在1節點發現發現pdb的open_mode爲MIGRATE ，2節點正常

SQL> show pdbs

    CON_ID CON_NAME                       OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------
         2 PDB$SEED                       READ ONLY  NO
         3 PDB11G                         MIGRATE    YES

重啓一節點pdb，恢復正常。
