如何连接oracle 12c可插拔数据库

启动根容器：[oracle@eric ~]$ export ORACLE_SID=cup[oracle@eric ~]$ sqlplus / as sysdbaSQL*Plus: Release 12.1.0.2.0 Production on Wed Jan 21 16:00:06 2015Copyright (c) 1982, 2014, Oracle.

CON_ID NAME---------- ------------------------------         1 CDB$ROOT                        ---根容器         2 PDB$SEED                        ---种子容器，只可读         3 TEA                             ---自己创建的可插拔数据库

SQL> conn c##eric/gaoConnected.               ---连接成功

切换容器：首先启动自己创建的容器数据库：SQL> alter pluggable database tea open;   ---首先启动PDB数据库

SQL> alter session set container = tea;

Session altered.

SQL> show con_name           ---查看当前所在的容器名CON_NAME------------------------------TEA关闭可插拔数据库：SQL> alter pluggable database tea close immediate;Pluggable database altered.
