CDB 有sid pdb 不能用sid

sqlplus rick/ @rac1:1521/pdb1

sqlplus rick/ @rac2:1521/pdb1

[c:\~]$ sqlplus system/[email protected]:1521/cdb

SQL> exit 

[c:\~]$ sqlplus system/[email protected]:1521/cdb1 只能用服务名 sid不行

 请输入用户名:  
ERROR:
ORA-12560: TNS: 协议适配器错误

[c:\~]$ sqlplus system/[email protected]:1521/pdb1

SQL> 

[oracle@rac1 ~]$ export ORACLE_PDB_SID=pdb1

看起来还是用CDB进去做了个切换，所以PDB的用户登录不了
[oracle@rac1 ~]$ sqlplus system/oracle

SQL> select *from rick.pdb1tab;

no rows selected

SQL> show pdbs;
SP2-0382: The SHOW PDBS command is not available

------SID pdb11不行，不存在

1. 通过alter session set container切换到PDB

登录到CDB，通过alter session set container切换当前的容器为PDB，

2. 通过ORACLE_PDB_SID

如果是18c、19c以上，可以设置ORACLE_PDB_SID环境变量的值，然后再登录，就是这个PDB，

3. 通过设置tnsnames.ora

配置一下tnsnames.ora，其中的service_name设置成PDB的名称，

再通过tns，登录到数据库，就是当前PDB的环境中，

4. 通过EASY CONNECT
通过EASY CONNECT，指定"/"跟着PDB名称，就可登录PDB，

如果是PLSQL Developer，Database中输入EASY CONNECT的"@"跟着的字符串，就可以登陆了，

如果是SQL Developer，“服务名”填写PDB名称，就可以登陆了，

5. 通过JDBC程序的连接

如果是连接PDB，用"/"跟着PDB名称，

jdbc:oracle:thin:@ip:port/pdb_name

如果连接CDB、12c以下的，不用"/"，用":"，

jdbc:oracle:thin:@ip:port:SID(/SERVICE_NAME)
