Home -> Community -> Mailing Lists -> Oracle-L -> RE: Third party application - perf tuning...etc.
Dennis,
The ERP vendor started off using Informix and ported their application to Oracle. We are 1 of 2 Oracle installations and they do not have much Oracle expertise in their company - they don't provide any administrative type manuals for the SA or DBA with respect to their products. I wish they would write an Oracle chapter or at least release an internal document which would explain all this. I do think that with their new release, they will be providing some tips for tuning so maybe I can just hold off until then.
The on-line forum is a great idea and there is one in which we actively participate.
Thanks,
Saira

Here is my tip. Every vendor must take an approach and if they
support
many databases there will be some compromises in their architecture. The
vendor probably has a chapter in a manual about how they interface with
Oracle. Read this, but don't skim it like most of us do because we have
way
too much to read. No, ponder each word and try online experiments to try
and
learn what every detail means. In a former life I worked for a vendor
and I
wrote that Oracle chapter. For some reason it is hard to write that sort
of
thing so everyone can understand it. Once you really understand the
vendor's
approach, you are miles ahead in understanding your tuning alternatives.
Also if it is an ERP vendor, there is probably an online user forum
somewhere and you can get a lot of specific advice there.

efforts?
List,
I begin with an apology for repeating something that has probably been asked before in different words.
We use an integrated ERP/WMS/Query application provided by a vendor but we do not have the ability to change any code.
How do I know that my Oracle database is running optimally (if there is such a thing)?
Obviously I cannot rewrite queries in the application code (which is 4GL code BTW). So what other aspects of the database can I change/tune? I can definitely see some costly SQL statements when I feel curious and want to check what's happening on the database. But isn't cost all relative?
Are there any recommendations for articles, white papers, books on how to tune the database for a third party application?
Also, I will be attending the DBA/Developer Day in Toronto on Monday October 6. I am looking forward to the sessions by Tim Gorman, Tim Quinlan and Michael Abbey. Anyone else attending this conference?
Thanks in advance,
Saira
