Oracle 12c开启scott账户

共计 781 个字符，预计需要花费 2 分钟才能阅读完成。

在 Oracle 目录 app\orcl\product\12.1.0\dbhome_1\NETWORK\ADMIN\ 下 tnsnames.ora 文件最后加入以下内容

PDBORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = PDBORCL)
    )
  )

然后进入 sqlplus 连接登陆 sys 账号，运行以下语句

SQL > conn sysYouPassword as sysdba;
SQL > alter session set container = PDBORCL;
SQL > startup
SQL > conn sys@pdborclYouPassword as sysdba;
SQL > alter user scott account unlock identified by tiger;
SQL > conn sysYouPassword as sysdba;
SQL > CREATE OR REPLACE TRIGGER open_all_pdbs
    AFTER STARTUP
    ON DATABASE
    BEGIN
    EXECUTE IMMEDIATE ‘alter pluggable database all open’;
    END open_all_pdbs;   
SQL > shutdown immediate
SQL > startup

至此已经可以使用账号 scott@pdborcl 密码 tiger 登陆了
