关于Oracle 12C pdb用户无法登录的问题

新装了oracle12c，对新的CDB和PDB用户如何登录一直一头雾水，经过一晚上的查找，终于解决。

sqlplus /nolog -> conn /as sysdba 登录到oracle

将session切换到PDB下alter session set container=pdborcl

建立表空间create tablespace tablespace_name datafile '/home/oracle/var/data/tablespace_name.dbf' size 500m autoextend on;

查看表空间select tablespace_name,file_id,file_name from dba_data_files;

建立用户create user table_name identified by password default tablespace tablespace_name;

对用户授权grant dba to toolbar;

提交commit；

conn toolbar/toolbar@pdborcl

ERROR:

ORA-01017: invalid username/password; logon denied

始终无法登录

设置TNS_ADMIN

export TNS_ADMIN=/home/oracle/app/oracle/product/12.1.0/dbhome_2/network/admin

依旧没有解决

conn toolbar/toolbar@orcl

ERROR:

ORA-12514: TNS:listener does not currently know of service requested in connect

descriptor

出现TNS错误，应该是TNS脚本的问题

查看services，发现应该是pdborcl的服务名有问题

select name,pdb from v$services;

NAME                   PDB

------------------------------ ------------------------------

pdborcl.localdomain           PDBORCL

orclXDB                CDB$ROOT

orcl.localdomain           CDB$ROOT

SYS$BACKGROUND               CDB$ROOT

SYS$USERS               CDB$ROOT

在tnsnames.ora里面加入

PDBORCL =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = pdborcl.localdomain)

    )

  )

conn toolbar/toolbar@PDBORCL

Connected.

OK啦

^_^祝玩得愉快
