本文主要是介绍TimesTen 与Oracle 数据库 12c的结合，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
之前的例子都是TimesTen与Oracle 11gr2结合，今天试了一下与DB 12c的结合。
从TimesTen的角度来说，12c和11g没有区别，都是通过tnsnames.ora来连接，主要的工作还是在12c这边。
本文介绍TimesTen 11.2.2.8.11和Oracle DB 12.1.0.2.0的结合，平台为Oracle Linux Server release 6.6
安装完Oracle后，已有一个PDB:pdborcl，以下是一些常用的12c命令
主要的工作是用alter pluggable database pdborcl open将PDB启动，并且利用netca定义tnsnames.ora
[oracle@tt12c ~]$ . oraenv
ORACLE_SID = [orcl] ? orcl
The Oracle base remains unchanged with value /u01/app/oracle
[oracle@tt12c ~]$ echo $ORACLE_HOME
