Home -> Community -> Mailing Lists -> Oracle-L -> RE: newbie dba question
Thanks very much to everyne!
I should've told you, first mistake sorry, that this is ORACLE 8.0.6 - can I run STATSPACK? Or should I stick with bstat/estat? I will be running stats during times when performance is normal nomal. But what steps in identifying the slowdowns in performace should be taken WHILE the issue is hot and users are on the horn with it? Obviously, they want FAST fix, magic stick. Their thinking is that there is a switch you turn on and that's it you're going fast again. Is there something that can be done in a short time window while the issue is present?
Thanks again!

When the system start to experience performance problems, then start drilling down to identify the issues. Use v$ tables as well as statspak more frequently. Additionally, when you find the sessions causing problems pull the sql and work with the developer to tune it, or identify hot objects you need to manage. Run the 10046 trace on the sessions and collect information on the waits etc. A good place to look is the www.orafaq.com for past list comments/information. A helpful book is Oracle 101 performance tuning by Gaja, Kirti, and John. You can also go to the hotsos site and run your reports through the YAPP to help identify bottlenecks.

Hello Gurus,
I heard that if I can get great ORACLE advice, this is the place, so here is my question. I've been asked to take over an existing db in production. What would be the right way to get a "quick" understanding on what's happening in it in terms ways for proactive tuning? I am just getting started while trying to be ahead of the curve. Is this something I should be looking into, or is it more like if it ain't broke, don't fix it? :). It'd be nice to get started and have a good view on what's going on. Also, can someone can share their experience on what can be done when customers report intermittent, but rather dramatic slowdowns in the system. Please note, the slowdowns are reported to be occurring in the entire system. What would be a good place to look when this happens and get some quick feedback?
Thank you very much!
Best regards,
Alex
