OBIEE to DB2 AS400 connectivity

user641186Oct 1 2009 — edited Oct 5 2009
Hi all,
it is not clear to me how to set up the connection to a DB2 on AS400 database.

Using BI Administrator, on the Physical layer, when I use "New Database" functionality
in the "Data source definition section", there is a combo box called "Database":
which option should I choose :
- ODBC Basic (or Advanced) ?
- DB2 AS/400 ?
in this case, when I go to the Connection pool definition,
in the "Call Interface" combo box, which option should I choose:
ODBC (2.5, 3.5) ? or DB2 CLI (Unicode) ?
and which values should I enter in the below fields ? (Data Source Name, User Name, Password)


- should a specific ODBC driver be installed ?
- or should I use one of the Odbc drivers that are installed during OBIEE installation (e.g. MERANT OEM 5.2 32-BIT DB2 Wire Protocol ) ?

Thanks a lot
Silvio

Hi,

I'm not really sure to understand what your question is about as you talk about dimension first and then about a prompt on a column ....

If you have a "Year" column which is used in a prompt and instead of YYYY you want to display YY-YY (so 2017 => 20-17 etc.) then it will be a string, and you can simple cast the year as string and then use substring to split the first 2 characters , concatenate the '-' and add the last 2 characters.

But it will not be "Year" anymore, it will be the formula you wrote as string. So all depends what you want to do with it.

Not exactly sure what you mean but if you generally want years to display as YY-YY then the best way to do this is to add a column containing this value to your time dimension.

Beware of putting function logic on time measures that you then use as filters.

This will have a very real impact on performance.

Better is either to have the values populated in the format that you want in the data warehouse, or if that is not possible then tell the end user population to live with it, the trade off on speed is not worth the cosmetic appearance!

Thank you all, we were able to efficiently convince our customers this unnecessary cosmetic change will lower performance and was able to keep it in the same format as a year should!

WTH just happened? A customer listened to community advice? Lollipops for everyone!

LOL, I was thinking the same. A bold move but worked out due to the technical advice provided on this thread regarding unnecessary changes! Cheers to all !
