Unix上基于事务的中间件(VP)的时钟管理方案

详细地阐述了VP的时钟管理方案的原理和具体实现，从算法的时间和空间的开销角度对该时钟管理方案进行了分析，从而表明该方案能够较好地解决VP的时钟管理问题。该时钟管理方案的突出特点是：巧妙地将物理时钟算法和向量逻辑时钟算法融合在一起，相辅相成，而且采用HOT—STANDBY设计思想提高了时钟管理的系统可靠性。

A Clock Management Solution of VP - An Unix's OLTP Middleware

This paper outlines the theoretical and practical issues of the algo rithms at first, then it analyses this solution from the general rules for the c ost of space and time. The above all points out that the solution can resolve th e VP's clock management problems. The outstanding characters of this solution ar e as following: merging the physical clock algorithm and logical clock algor ithm perfectly and improving the availability of clock management of through ad optin g the HOT-STANDBY methods.
