Hi Veronica.

A lot changed since this post, TM1 got up to 9.5 and things got better.
Still hoping to write about this (next week, maybe).

Hi Ykud,
Thanks for sharing your findings.
Were you able to resolve the locking issues in TM1?
I heard this may be an issue with TM1, just trying to look into it.
Any feedback is greatly appreciated.

[...] PS: Just to notice, they say aggregate awareness for Cognos BI is in beta-testing. Just after I spent so much space promoting database-level aggregate navigation. [...]

Comment on DMR’s pros and cons by ykud

Hi, Andrei.

I usually try to avoid 1 where possible (on Oracle sites, it means) by adding Materialized Views.
Agreed on all other points.
TM1 will change dimension limits a bit, it seems )

Security will remain a main issue though.

Thanks for sharing,
Yuri.

Yuri,
I’d share some add-ons from my experience.
I usually follow the next way:
1. Trying to create aggregated tables and use them as back-end to the DMR (lots of the analyze about indexes user’d need) meta-data model.
2. Agree with you that are easy to start from using DMR.
3. Only in case of performance issue I am gonna start using the Cubes.

Cubes vs. DMR:
Timeliness – Contain “real time” data (DMR); Data in cubes need to be updated (Cube).
Flexibility for user – Static (DMR); Dynamic (Cube).
Usage – Management/Statistical reporting (DMR); Reporting and Analysis (Cube).

Then it’s always too much important to find out about dimensions to use in one Cube, ~4-5 it’s pretty critical amount on my mind.

And I cannot say anything about security. Lots of time I had to refuse from start using Cubes when the security scheme was pretty complicated with a lot of dynamic combination especially when I read security information from RDBMS.

Good Luck!

Dear Yuri,

My problem is solved.
I guess it is because that I used “&” as part of Macro’s name. Just change its name and it works fine as usual. It’s odd!
Still want to say “Thanks you”.

Best Regards,
James Yang

Dear Yuri,
I am a professor in Taiwan and working an EP project for a Manufactory. We have talked before and your advices helped me a lot.
There is a new problem regarding to Publishing Macro to Connection in Contributor Administrator Console.
It was very OK previously.
However, today I got an error message “You do not have rights to publish the Macro to IBM Cognos Connection.”,when creating a Macro.
How can I have the rights for publishing Macro to Connection back again?

Thanks in Advance!
Best Regards,
James Yang

I am not sure if you have auditing turned on in your environment. If you do, do you see several hundred logon for users? If you actively use it, may be check for your id. For an active user, who runs macros/events we see about 2k to 3k logons in an 4 to 8 hr window! And each of the logon is alomst a minute after the previous one.
