OBIEE heats up, OBIEE blogging cools down

Thanksgiving holiday, pre-Christmas routine, and a general lethargic state due to the weather. They don’t help us to write more about OBIEE. Also, I have a feeling that everyone has a feeling that all OBIEE topics have been covered. So everyone is just waiting for 11g – and then there’ll be a race.

RNM1978 posted a very good visual representation of OBIEE documentation –
From one side, bad documentation has opened a niche for experts to blog and discover new things. On the other hand – if it’s not in the docs – it’s probably not covered by Oracle’s support – so some companies might be wary of installing new things.

As far as a new forum – I’m still working on identifying an open-source forum platform that would have all features that OTN has and more. There’re some candidates – but I’m still in the process of search.

I will be honest – I still check OTN – however, I give it a quick glance and then just leave. I still give respect to everyone who’s answering questions, however silly lazy ones. I’m wondering if the influx of new OBIEE will contribute to rates pushed down in the future. For one thing I’m sure now that there’re 2 different kind of “freshers” – one making a transition from another BI tool (Cognos, MS Analysis Services, Discoverer) or a closely-related area (Oracle data warehousing, OLAP) and those who have taken “$600 courses”. It’s very conflicting – since everyone has to start somewhere. However, starting by spamming OTN isn’t the right way to do it.

This is why I was actually against point system when it was implemented – it incentives seasoned consultants reply to silly questions – the ones they would have left without attention before.

Anyway, I hope everyone had a nice break! Back to work! And please stay healthy and well.

Admintool Check-in changes: Internal Assertion Error Condition

If you’re running OBIEE under 64-bit Solaris – this might be of use. I just want to add from myself – that it’s not a good idea to change repository in online mode.

Admintool Check-in changes: Internal Assertion Error Condition FALSE , file server/Utility/Generci/NQThreads/SUGThread.cpp, line 515 [ID 820803.1]

When checking in changes in Admintool, you are getting the error:

nQSError:28019 Near line 230: In the metadata expression … the following error occured nQSError 46036 Internal Assertion Error Condition FALSE , file server/Utility/Generci/NQThreads/SUGThread.cpp, line 515

This is a defect:

Bug was logged for with OBI server on Solaris 64 bits

Although the abstract mentions Essbase the bug is reproducible against any database.
But only when OBI is on 64 bits solaris platform.
It applies to all versions from OBI and later.

Test case:
From Admin tool created the new rpd (i.e. physical layer) and Drag-Drop
the db to Business model & Presentation layer then tried to Check In / Save
form Admin tool in Online mode but I observed the below error form Admin tool
window as well as NQServer.log
Error Message:
[46036] Internal Assertion: Condition FALSE, file server/Utility/Generic/NQ
Threads/SUGThread.cpp, line 515.
2007-11-27 04:44:12
[46036] Internal Assertion: Condition FALSE, file
Threads/SUGThread.cpp, line 515

Off line mode able to check-in or saved sucessfully.

Also we only had the error on a Business Model that had been dragged and dropped from the physical.
The workaround is to modify the NQSConfig.INI file.

and restart the OBI server

Increasing thread stack size (by setting SERVER_THREAD_STACK_SIZE to a bigger number) is the solution to this issue in all versions including

Increasing thread stack size requires more memory from the server machine.
That is the only impact it should have. But increasing from 256k (default) to 512k is a minor change

This defect will be fixed in the next main release

Creating a pivot table view with mixed granularity

Hello everyone.

I just realized that this post is inspired by Venkat.

I’m finally posting a solution to the problem I’ve identified a while ago related to a specific Pivot Table View. I think the final outcome should look something like this image:

Pivot table view

To get this result – I’ve used the “New calculated column” menu on the pivot table (circled in red):

OBIEE pivot table menu

Then, what you really need to have in the Columns is the most granular level column (sounds redundant – in this case it’s a Date column). I used Excel to quickly generate formulas, such as this for Q1.  It’s really easy to generate these formulas below. I hope it’s pretty self-explaining – you add things up in a granular level – this way you can combine things – that you wouldn’t be able to combine otherwise:


Calculated item OBIEE
Calculated item OBIEE

The same logic works for Q2,3,4. For individual dates, it would be the same idea:


And for months, it’s the same logic:


To sum up  – by using the “calculated item” feature of pivot table view – you can create reports with mixed granularity on them. The pros are that you’ll be able to support legacy views (in some instances it’s absolutely critical to mimic existing view). The cons are that it involves some manual entry / data manipulation and that it’s not very flexible (I couldn’t find out how to use variables in this example).

Last thing – it seems as first column gets added on the left and the consequent ones to the right – keep this in mind while designing this view – since I’ve noticed you can’t really manipulate with the locations of the calculated columns.
