What is the exam guide for 1Z0-591?

Partners ask their employees to get certified because there are fixed numbers of certified people fixed by Oracle to be listed as preferred partner in BI or another domain and things like that. Also some levels of partnership require a minimum number of certified resources and things like that.

So aren't these certificates proof that they have technically knowledgeable people??
Otherwise Oracle can easily conduct Skype interviews and assess their knowledge, right?
So, aren't these certifications de facto successful interviews??

Not at all ... I'm telling you a certification is not the vehicle to ride to make the change ... get the VM, get to know the product, make an impression on someone in the BI space and get an interview. The switch is possible.

Nope it's just that the OBI certification has never been treated with as much attention or anywhere near as much detail as for example the database certifications. It's a bought technology stack - not an in-house product like said database.
Again it depends on what you expect from a certification. If you expect to do it and know everything - ref.:

then you will DEFINITELY be disappointed since "learning for the certification" will not guarantee you technical knowledge.
As for the Partner part Gianni gave you the answer. It's about Oracle's partner matrix and agreement. And as for your follow-up questions:

No, no and no respectively. It's an indication but no proof. I'm sure we could spin this thread into an endless story of "more than questionable stuff purely certified people have done" and a counterpoint of "mindblowingly awesome stuff that non-certified people have done".

This. Thank you. Knowledge and understanding can never be trumped by a piece of paper where it counts. Certified hordes can never stand up to a small group of proper experts.

I don't think getting the certification is right for you. I've never been hired, or heard anyone who has, based on whether I have the certification or not. Just like @Thomas Dodds, I did the certification AFTER I got a job with a partner and had been working with BI for quite some time due to Oracle's partner requirements.

So, how do you think that it will take an average developer to do this? 2 months? 3 months??
If you start doing it, how long will you spend?
Can't we kill 2 birds with one stone? i.e. Do the syllabus in the certification, i.e. learn the theory part using the manuals, and try them in the VM?

I am not saying to hire me as an BI architect.
I am saying to hire me as a junior OBI developer. After a couple of years of toiling, I can jump to SSE or even architect level, right?

Sure you can do what you want ... and we're not telling you not to do it. We're telling you not to set your expectation unrealistically. Do not stick to the 'book' side of it alone -- be very ready to demonstrate knowledge.
As for how long ... who knows? That's a very individual thing. I've had people excel at this with no prior experience and I've had people struggle for years to really understand the concepts and fundamental principles behind the tool.
Start with data warehousing - it's tool agnostic; most tools for BI employ some variation of DW principles. So once you understand DW, then you look at the db schema in the VM and see why they have the tables the way they do. Then you can translate that db information into the physical layer of the RPD, which then you can study that aspect. Then you move to the BMM (logical) layer (which also employs DW principles). So you can see a path to pursue in a (pardon the pun) logical fashion. Also know how to track down queries and bottlenecks in performance. A developer who knows this stuff is worth his salt -- the senior developers and architects won't be bogged down my him. Security knowledge in OBIEE is a must for everyone.
Security understanding is a must for everyone. Most of the visualizations are pretty easy (especially with the modeling done right). One area of the visualization you should be fluent in is the best practices of what visualization to use to convey the proper 'story': how many times have I seen a line chart where there is no time attribute as the x-axis? Know these leading practices.

So, that is exactly what I am also talking about.
How did these people get a job in your company as OBI developers without any past experience?
