cache group connect to oracle功能概述
cache group connect to oracle是TT中的最重要一个选件，该选件为TT数据与oracle DB中数据同步提供了有效的管理机制，通过缓存融合技术使TT和oracle之间的无逢连接，实现数据的实时刷新传递。
通过以下实验了解创建一个readonly cache group的过程
This document provides an overview of how locking and concurrency control operate in TimesTen.
It is accurate for TimesTen versions 6.0 and 7.0. Earlier releases behaved somewhat differently in
some respects.
First, some key fact must be clearly understood:
1. TimesTen is a complete database, with locking, persistence, ACID transactions, recovery etc.
in its own right.
2. The Cache Connect functionality which allows TimesTen to ‘cache’ Oracle data is most
accurately thought of as a kind of ‘replication’ between TimesTen and Oracle.
3. TimesTen does not use any kind of distributed transaction or distributed locking as part of
replication and cache connect (since those mechanisms are slow and problematic). Continue reading ‘Locking in TimesTen 6.0 and 7.0’ »
