你到底想解决什么问题?

是写数据库太慢,

还是读太慢,

还是想解决多人同时更新数据库的问题?

可能没说清楚，我的意思是：

我的网站项目可能会遇到大访问量的问题，（包含数据库访问或非数据库访问）。那么，使用weblogic可以支持多大的并发用户，而且通过什么方式，怎样配置weblogic可以使它有更好的性能？

如果是这样,我建议你先做一下压力测试,分析一下能否承受的了你所期望的负载.

不过我觉得大部分的系统问题在于应用程序的体系结构,一般来说BEA的weblogic使用web server是apache它的性能不错的,可以提高JVM的内存,连接资源.

对于常用的一些程序你可以找出来优化

before doing any monitoring, load testing or tuning, you need to setup a detail model, a goal, even it's hypothetic.

I had help a customer develop a site host 17,000 users using weblogic6.1, it's a data entry type application, we basically gone thru all turning possibilities on network, weblogic(cluster) and database. It's months of work. But I am afraid you won't get any specific answer as the way you post the question. You need to explain the natural of your app, your reqruiement on throughput and response time. memory estimation for invidual user or transaction etc. If you have not done the ground work, do it first.

Just my $0.02
