DBS PL/SQL内存管理实现

Designing and Implementing of Memory's Control With DBS PL/SQL Engine

讨论了DBS PL/SQL中内存管理的设计思想和实现技术.在DBS PL/SQL中将内存上下文分为语句类型、表达式类型、全局类型、编译类型、包类型、函数类型和返回语句类型.经过测试,DBS能够稳定高效的运行,没有出现内存崩溃的现象.

This paper discusses the designing and implementing of memory＇s control with DBS PL/SQL engine. It mainly contains memory＇s allocating, memory＇s reallocating, and memory＇s releasing in memory pools. Tests on DBS PL/SQL engine show that it functions stably and efficiently with no collapse.
