PDB起動中に切断しようとした
(対策) PDBを停止してから切断する

SQL> alter pluggable database orclpdb2 unplug into '/opt/oracle/oradata/ORCLCDB/orclpdb3/orclpdb3.xml';

alter pluggable database orclpdb2 unplug into '/opt/oracle/oradata/ORCLCDB/orclpdb3/orclpdb3.xml'
 *
ERROR at line 1:
ORA-65025: Pluggable database ORCLPDB2 is not closed on all instances.

SQL> alter pluggable database orclpdb2 close;

Pluggable database altered.


SQL> alter pluggable database orclpdb2 unplug into '/opt/oracle/oradata/ORCLCDB/orclpdb3/orclpdb3.xml';

Pluggable database altered.

切断したPDBにsqlcl接続した
(対策) PDBをプラグして起動する

切断中のPDBを起動をかけた
(対策) 再接続してから起動する

SQL> alter pluggable database orclpdb2 open;

alter pluggable database orclpdb2 open
 *
ERROR at line 1:
ORA-65086: cannot open/close the pluggable database

インスタンスを間違えて起動した
(対策) 正しいインスタンス名を指定する

SQL>

SQL> alter pluggable database orclpdb22 open;

alter pluggable database orclpdb22 open
 *
ERROR at line 1:
ORA-65011: Pluggable database ORCLPDB22 does not exist

アプリケーションPDBをCDBか再接続しようした
(対策) アプリケーションシードから実行する

SQL> create pluggable database orclpdb2 using '/opt/oracle/oradata/ORCLCDB/orclpdb3/orclpdb3.xml' nocopy;

create pluggable database orclpdb2 using '/opt/oracle/oradata/ORCLCDB/orclpdb3/orclpdb3.xml' nocopy
 *
ERROR at line 1:
ORA-65240: not connected to an application root

切断済みのPDBに切断コマンドを投げた

SQL> alter pluggable database orclpdb1 unplug into '/opt/oracle/oradata/ORCLCDB/orclpdb1/orclpdb1.xml';
alter pluggable database orclpdb1 unplug into '/opt/oracle/oradata/ORCLCDB/orclpdb1/orclpdb1.xml'
*
ERROR at line 1:
ORA-65265: PDB cannot be dropped or unplugged.

PDB切断時に指定したxmlファイルの拡張子が.xmlなど有効なものではなかった
(対策)拡張子を.xmlなどにする

SQL> alter pluggable database orclpdb1 unplug into '/opt/oracle/oradata/ORCLCDB/orclpdb1/orclpdb1.xml.20200116';
alter pluggable database orclpdb1 unplug into '/opt/oracle/oradata/ORCLCDB/orclpdb1/orclpdb1.xml.20200116'
