Oracle 19C 添加scott用户

1. 为要创建scott用户的pdb添加tns

vi $ORACLE_HOME/network/admin/tnsnames.ora

PDB1 =
   (DESCRIPTION =
     (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.21.96)(PORT= 1521))
     (CONNECT_DATA =
       (SERVER = DEDICATED)
       (SERVICE_NAME =pdb1)
     )
   )

2. 修改脚本

位置：$ORACLE_HOME/rdbms/admin/utlsampl.sql

将conn scott/tiger改成scott/tiger@PDB1

3. 登录到数据库，并切换到对应pdb，执行脚本

sqlplus / as sysdba
alter session set container=pdb1;
show user
show con_name
@$ORACLE_HOME/rdbms/admin/utlsampl.sql

执行结束会自动退出sqlplus

4. 验证

sqlplus scott/tiger@PDB1

能登录即可
