Krishnan,

Surely the post you are commenting on gives you a good start on answering your question? You are asking how to run report execution on OBIEE – this is the subject of this posting and I can’t see how someone could set the answer to you better, short of coming on site and doing it for you…

regards

Mark

Can someone help me…. we are experiance very slow response from OBIEE reports. Reports taking much time on OBIEE as compared to SQL run on SQL prompt or on toad. Example report took around 1 hr to finish whereas its query on SQL or toad took only 3 minutes to complete.

Can you please how and what needs to be done to tune reports execution on OBIEE.

Mark,

I am facing one problem regarding DAC. When the one execution plan fails and if the next execution plan time is passed till we fix the first one, we have to start all the execution plan manually. Is there any to get rid of this problem.

Thanks,
Rutuja

Can anyone please confirm. If I create a new execution plan in the DAC, what is the query that is thrown into the database to create the ordered tasks listed in the DAC. Where can I find this query log.

Hi all,

The control user access mean different user can only see particular report.

Hi all,

Do Obiee have a function to control user access to view the report template? Can some one show me.

Could you clarify the difference between the BI Server Cache and the BI Presentation Cache.

Let’s suppose that we have just installed OBIEE and BI Server Caching is enabled. When we run our very first Answers report, the BI Server will cache the data result set, which can be used by other users who run the same report or a report which would return a subset of the cached data. This cache data remains in the BI Server cache until the cache is purged.

Does the BI Presenation cache (default settings – 60 min retention I think) also have the same data set ? If so, is this only available to the
1. same user ’session’
2. same user different session
3. all users

Also, from the Administration -> Manage Sessions option in Answers, the ‘Open Cursors’, is this a reflection of the BI Presetation Cache? It seems that when I run a query there is an entry. If I then log out and back in, the entry for the Open Cursors has disapeared. This make me think that Option 1 above is more likely.

The tag for the BI Presentation Cache, can I assume that this is for all users and not a per user/session value.

Appreciate all replies.

Arif

Mark,

Great write up you have! I have played around quite a bit over the past year with usage tracking and have found a small caveat to the table just above point #5. It might be worth noting; while usage tracking does technically log logical sql to a database, it only logs the first 1024 bytes of the sql text. So if you have any sort of complexity to your particular request then it will more than likely extend beyond that threshold.

Thanks!

@Mohandas
Thanks for spotting the typo. They occasionally creep into our writing and sometimes are hard to spot especially if we put in the wrong word!
