Hello David,
It's not a problem to trace a session and tune a report for me. Let me explain my situation some more. At the moment i have one or two dedicated Business Objects sessions for all the B.O. reports that are fired upon the database. The problems i face are the following:
(1) I only see a handful of SQL-statements, not a report name they belong to. I'm not sure if B.O. is capable of giving a name to oracle.
(2) I would like to have an overview of which reports ran, together with the total runtime. With an other applications, i saw that every report inserts its begin and endtime in a table, so you can easily make the mentioned overview. This can be done for trendanalyses and for estimating a tunings effort. ( e.g. i sometimes refuse a performance incident because it's a report that runs just 3 times a month for a total of 4 hours. Too small a fish in my shop.) . For trendanalysis i can see which report starts to misbehave due to e.g. planinstability.
I am not allowed to talk directly to endusers, so i can't ask who is running which report. I might ask via via which reports they deem tunable, but i am afraid that a lot of noise will get on the line with such question. ( for example, in an other case my question about the enduser experience was ansered with " we ( functional management) know what the customer wants" : my questions were not transferred to the endusers )
I am still on a 9.2 database. I have no experience with ASH , so i don't know if installing the S-ASH scripts from the ASHmasters can be part of the answer.
Surely such overview can be made, or should be handy?
Regards,
HV
