TimesTen 与Oracle 数据库 12c的结合

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 $ORACLE_HOME
/u01/app/oracle/product/12.1.0/dbhome_1 [oracle@tt12c ~]$ sqlplus / as sysdba

使用netca配置tnsnames.ora，如下：

然后登录：
[oracle@localhost admin]$ sqlplus sys/Passw0rd@pdborcl as sysdba

以下测试TimesTen与Oracle的连接，第一次测试出了个小错，原因是Oracle与TimesTen的字符集不一致，看来passthrough模式也需要两个数据库的字符集一致。

[oracle@tt12c ~]$ sqlplus tthr/oracle@pdborcl
