CDBに共通ユーザを作るときの注意事項

More than 3 years have passed since last update.

使用環境はOracle12c。

CDBに共通ユーザを作成するときは、
ユーザ名の頭に「C##」を入れる必要があるので注意、という話です。

ユーザの作成方法は下記。
sqlplusでログインし、CREATE USER文を実行します。

[oracle@sample ~]$ sqlplus / as sysdba
SQL> create user c##test00 identified by welcome1;

ユーザーが作成されました。


※「C##」を入れないと、下のようなエラーが出ます。

ORA-65096: 共通ユーザーまたはロール名が無効です

作成したユーザを確認するときは、dba_usersからselectします。

SQL> select username from dba_users order by 1;

USERNAME
----------------------------------------

C##TEST00
