Re: Cognos 8 BI process architecture and capacity planning

Hi Albert,

I haven't had a chance to work Business Insight much yet, so I'm don't have definitive answer here.

Can you monitor usage on the servers? In my experience Insight reports tend to be CPU intensive, do you notice 100% spikes?

Just adding a windows perfmon trace (memory, cpu) for a couple of days can give you quite a lot info on that.

Any ideas out there on how to optimize for large user base of Business Insight? There seems to be a serious lag when we have multiple concurrent users on this capability.

Ooook, I'll have a look at it someday. Is it the same Cubewise Documenter http://www-304.ibm.com/partner...

Depenency checking of any objects is a complex task, it took me abt whole 2 months to develop TM1 Documenter software.
Its a 15 days evaluation software.By the way, I believe its useful (to TM1 Developers).
Please provide me ur feedback

Thanks for that.

I can't see the source code in the archive — how do you check cube dependency?

Hi,
you also can try TM1 Documentor. It has documenting feature as well as dependency checker
You can download it from:- http://www.mediafire.com/?98q9... or https://rapidshare.com/files/3...

Re: Do you want your TM1 go twice faster on Intel-box? Turn HyperThreading off

Hi, Mike.

Send your test results, I'm really interested (got a few already, craving for more).

About PVUs: I was thinking more in terms of a situation when you have a virtual machine for TM1 and you just have more cores on the host with only a couple shipped to TM1 VM, therefore you'll have a distinct chance of boost. But thinking again, am I arrogant enough trying to outsmart IBM sales when it comes to licence cost or inventing perpetum mobile?
I think I'll ask my IBM contacts and go through license docs myself and then will return with an answer of whereas this is possible. I've read something specific about IBM Power TurboCore, but can't remember anything on Intel chips.

Anyhow, the same holds for user-based licensing -- buy more cores, get Turbo Boost ;)

Great article! I look forward to testing some of these observations out.

However, one thing I question is this advice:

"When buying a TM1 server with Intel CPUs, buy way more cores than you’ll license. Physical cores, not logical."

Maybe I'm misunderstanding your point, but wouldn't this be in direct violation of the IBM license agreement? You seem to be indicating that you could buy 16 cores and only license 4 cores - I can't see how that would ever be legal/accepted by IBM. I don't see "we only ever use 4 of the 16 cores" being a valid argument under the current PVU license structure. But, again, maybe I'm misunderstanding something about Turbo Boost or your point above...

Hm, must be some browser cache -- downloading works fine for me (new archive, html in it, etc).

Benson Lo — Fri, 30 Sep 2011 09:22:27 -0000

Many thanks for your quick reply! The report_template.html file really works, though the new package content remains unchanged (checksum equals to prior version). Simply speak, there's no HTML file inside new package.

Hi there.
Please redownload the package, or just download report_template.html separately to the same folder and rerun the program.
Sorry for inconvenience.

Hi, I've got this error "jinja2.exceptions.TemplateNotFound: report_template.html". What could possibly be missing? Need to install any software package first, like Python?

Thank you, Kleist, I'll update the post accordingly.

But you had 2 separate URLs for internal\external users and 2 separate web-servers?

Re: Cognos 8 BI process architecture and capacity planning

Dave Kleist — Sat, 25 Jun 2011 07:12:19 -0000

One point I'd like to add - you can have multiple gateways in a deployment. I've done this when you need an external gateway for users on the Internet rather than the internal network. (Gateway components only).
