10g Key indicators

Question

We want the extract key data from the performance reports output to get a trend indicator.
I tweaked the sql scripts which came with the application and created a key indicator report. This is in a draft form right now and we plan to improvise it. Does anybody have any comment about the effectiveness of this report to catch trends in
1.surge in usage
2.proactively correct performance problems
here is the sql i created.
to run it pass in day as the first and the only parameter
and substitute a file whose download time you want to measure

Answer 1

In 10g this is not quite as simple as 11g. To create a custom measure that calls an OLAP DML program you need to either:
1) Download the Excel Utility from the OLAP home page on OTN:
http://download.oracle.com/otn/java/olap/SpreadsheetCalcs_10203.zip
but check the readme first:
http://www.oracle.com/technology/products/bi/olap/OLAP_SpreadsheetCalcs.html
or
2) Use Warehouse Builder to manage your AWs. OWB allows you to automatically create custom calculations that call OLAP DML programs.
If you look at this posting on the Oracle OLAP Blog you will find an example of how to create an OLAP DML program and reference it from a calculated measure:
