Dear All,

Here, i am little bit confuse about the percentage of the term "execute to parse %". If it's percentage would be "-ve" means, SQL statement parsing lot but executing less. May be user running reports. Here, value is 50%, what should I suggest to client? Do i tell them that performance of database is fine?

Waiting for your reply...

Regards,
Ishika

"execute to parse %" from what? Don't you think it depends on the tool you use?

If you don't know then you are not skilled to the task that has been assigned to do, it is then better to way it and not make your job by a forum.

If you want to be this kind of work you must read Database Performance Tuning Guide.

Michel

In addition a simple search gives you this AskTom thread: execute to parse ratio.

I would handle this differently. You ask this:Quote:

which is not the correct approach. No client has ever telephoned the help desk to complain that "the execute to parse ratio is bad". They complain about things like "this report is too slow" or "this screen doesn't refresh fast enough". Focus on identifying the problem, in business terms, first. Only then can you look at possible reasons.

Dear John,

The database size is small. As of now, there are no performance issue. I have give feedback on this, to client. That's why i want to about it.

If the database is small and there is no performances issue so why worry about this?
Why not worry about IO performances or CPU performances or, as a major concern, Oracle version which is no more supported?

Your question is not wrong but you ask YOURSELF a question that is not pertinent for your case.
You have nothing to say to your client.

In addition, I think you didn't carefully read the links I provided as there are ALL the information you need (above all the second one). If you don't think so then explain why it does not answer your question.

Regards
Michel

Dear Michel,

I read your mentioned link and come to conclusion that even if execute to parse% is 2, database performance is good. Percentage below 0 is the problem. Am I correct here?

Ishika

Anyway performances are good unless there is a performances problem reported by users.

Ishika, I'll try again: you have missed the point!
Database performance is not GOOD or BAD according to some ratio. It is GOOD if your users find it acceptable, it is BAD if they do not find it acceptable. You said earlier that, to quote you, "As of now, there are no performance issue". Therefore, performance is GOOD. That is the only report you can give your client.

Do you understand what I'm saying? If not, you could Google "compulsive tuning disorder" which is a supposedly amusing term to describe pointless tuning activity.
