Article Description:
In Analysis Services 2008 there are 13 MDSCHEMA Dynamic Management Views (DMVs).
These DMVs describe cubes, dimensions, functions, measures, etc in Analysis Services database.Here is a diagram that I got after exporting structure of above DMVs into SQL Server database.
|
Comments:
One of the tasks that we developers hate to do is... generation documentation :-)
SSAS provides you with DMV, you can create a linked server and via openqueries can extract the info that you need (you can use that queries on SSRS to get a nice layout)
In this post you will get a tables diagram that will tell you which info can you extract from that DMV.

Article Description:
New SSAS 2008 DMVs allows you to easily access Microsoft SQL Server Analysis Services (SSAS) metadata – information about cubes, dimensions, measure groups, measures, etc. As with DMVs metadata information is returned in the data set format, it is very easy to build Reporting Services reports to generate documentation about your database.

Comments:
Quite useful, autogenerate cube documentation, dimensiones, hierarchies...

SSIS Compress File Task

Article Description:
It was only a matter of time following my post the other day about System.IO.Compression, before I put this into an SSIS custom task. Well, here it is.
|
Comments:
Excellent post... SSIS 2005 is getting old, it has some inherent limitations... no SFTP, no good tasks to consume XML, no native task to zip files !
In my case, we perform an extract and dump it into a csv file... that csv file extract it's huge, what about zipping it before transfer it over the network? (the ratio is hundred of Mb vs less than 10 Mb).
Checking in SSIS for that, we found that we can use Winzip or similar at command line level (try to convince the IT Admin to install such tool on their machines), use some commercial SSIS custom task (not expensive, about 500 $), or code it your self, using some of the open source libraries available (cowboy developer, let's reinvent the wheel :) ).
Hopefully, the folks from the Joy of Code have posted this excellent task for SSIS... zipping files task for free, excellent work !!!

SQL Server 2005 Report Builder and Basic Authorization
|

Entry Date: Jul 2009

Rating:

keywords:SSRS; Security;
|

Article Description:
I have a customer who needs to use Basic Auth with SQL Reporting Services 2005, so I wanted to make sure they could get at Report Builder too.
|
Comments:
Have your clients ever complained about an error when trying to execute Report Builder? Something like:
Cannot retrieve application. Authentication error.
Why this happens? This happens when the account that the user is using to login is different from the one that he uses to enter in SSRS. It's a bit crappy but click once just use the current identity of the logged user, not the one provided in SSRS to login. Solution ? Enable anonymous access to the folder where Report Builder binaries are placed.
More info:
ClickOnce always runs as a separate process on the client computer. The process identity is the default Windows user credentials. ClickOnce does not share session data with Internet Explorer or obtain the current user security context from Internet Explorer.
ClickOnce sends requests that specify Windows integrated security in the authentication header. If a server is configured for a different authentication type, the server will fail requests from ClickOnce with an authentication error. To work around this issue, you must either configure a server for Windows integrated security or you must enable Anonymous access to eliminate the authentication check.

SSRS OfficeWriter it's quite a powerful plugin... only a "but"... sometimes it doesn't install straight forward, here you will find manual steps to install it (just in case the wizard install fails).

Report builder is not the best tool for cube navigation / browsing, rather evaluate PPS Analytics, Excel Services... or at least upgrade to 2008 version.
Here you will find some limitations of the product applied to SSAS.

The HAVING clause

Article Description:
The fact that there's now a HAVING clause at all in AS2005 MDX doesn't seem to be publicly documented anywhere, as far as I know; it's one of those hidden features we found out about while researching 'MDX Solutions'. While George has a full write-up on how it behaves in the book (coming soon to a store near you) here's a quick overview of what it does...
Basically, it allows you to filter the contents of an axis without having to use the FILTER function.
|
Comments:
SSAS MDX sometimes seems to be like black magic, or too hard for a SQL Developer :-).
Interesting thing to take a look: HAVING clasule on an MDX statement.

Designing effective aggregations are a well known way to improve query performance (for the sake of AS processing time). As you may have noticed in Tip #2 of the of the Analysis Services Query Performance Top 10 Best Practices whitepaper, the best way to define effective aggregations is to use the Aggregation Manager sample application. Here we discuss one of the strategies for adding effective aggregations using this tool.
