CA ERwin Model Manager Implementation Guide

Appendix A: Microsoft SQL and SybaseServer Tuning RecommendationsThis section contains the following topics:Physical Tuning Parameters (see page 49)Server-Level Tuning Parameters (see page 50)Named Cache Configuration (see page 51)Database Tuning Parameters (see page 51)Database and Log Sizing (see page 53)How to Maintain an Efficient Database (see page 53)Physical Tuning ParametersThe mart is dynamic, with many queries and data manipulations performedwith each model save and load. Although the Microsoft SQL Server and Sybasearchitectures differ in some ways, the basic operation and configuration of bothserver environments is the same.The configuration changes that must be made to Microsoft SQL Server andSybase for optimum performance with maximum fault tolerance andrecoverability are provided.Hardware ConfigurationsConsider implementing CA ERwin MM on a multiprocessor system, especially ifmultiple data modelers are saving information simultaneously. Install thesoftware on a stand-alone Microsoft SQL Server, if possible, or on adevelopment computer. The database overhead noticeably affects otherdatabases running on the same system during save and load operations. If fewmodelers save and load simultaneously, the overhead is less.To improve caching performance, implement CA ERwin MM on servers thathave at least 512 MB of RAM.Appendix A: Microsoft SQL and Sybase Server Tuning Recommendations 49
