还有哪些参数对改善ORACLE性能有关呢? 请高手指点!作者: easytolab 时间: 2005-01-05 13:29 标题: ORACLE现在性能很不理想,请高手帮忙看看 processes=500时,是否semmns的值应比1024再大些?这是否影响ORACLE的性能?作者: sshd 时间: 2005-01-05 13:44 标题: ORACLE现在性能很不理想,请高手帮忙看看 you will need to tell how 性能很不理想. Is there any performance related data (collected using statspack, for example) from the past that was considered as acceptable?
the init parameters alone can not tell you anything regarding the performance.作者: easytolab 时间: 2005-01-05 13:49 标题: ORACLE现在性能很不理想,请高手帮忙看看 我在2台客户端开了6个应用去数据库里取字段
每个应用按每秒取200个来测试,相当与每秒一共发送1200个请求,另外每个应用都有一个返回时间响应值,现在每个应用都超过了1000ms,这么少的数量,时间太长了,不知道怎么搞的
另外机器配置是比较高的了,以前同样配置的机器,效率比这要高呀作者: sshd 时间: 2005-01-05 14:36 标题: ORACLE现在性能很不理想,请高手帮忙看看 I would suggest that you read $ORACLE_HOME/rdbms/admin/spdoc.txt
to see how to use STATSPACK to collect database perfomance statistics in order to help you or others to identify the performance bottleneck.
Adjusting the init parameters blindly may not help you.作者: easytolab 时间: 2005-01-05 16:34 标题: ORACLE现在性能很不理想,请高手帮忙看看 刚才说TKX的帖子居然没给贴上,再说一遍:Thank you very much!
