Hi,

I am using the OLAP feature of webfocus to generate a report.The problem is the report hangs if i have large amount of data to be generated.Is there any way to fix this.

What do you call a large amount of data.
If you can predict the number of rows you might consider not running the olap process.
The drill down would than be a more reasonable solution.
The number of rows you can handle are also dependand on the client system (Firefox or Microsoft or others) where firefox can do more than microsoft.

The Olap function is nice on a small amount of data.

When you say 'hangs', is it when retrieving into the spreadsheet? You may have to 'rollup' and not have as much detail for the report if you are bringing back all detail. There is a limit on how much the spreadsheet application can handle. Even the memory of the machine to which the information is returning can have an affect.

OLAP is IMO something else than Excel.
It's a bit confusing, you can do an olap in excel, but if Aditya says to use the OLAP feature of webfocus, it is the feature IN webfocus.
Nevertheless you are right aboout the limitation in excel. Only 65000 records, but who will work with that amount of records in Excel. (Who will work with Excel....)

Hi,

First to clarify on the OLAP feature.Webfocus comes with an OLAP feature that when used allows the users to drag and drop columns,filter data on the report itself.

Regarding the no. of rows fetched,i am fetching approx. 16,000 records.The report works fine when i generate a plain HTML report.But when i generate a HTML report with the OLAP feature enabled(OLAP control panel),it takes a lot of time to fetch the data hanging ultimately and hence i need to use the task bar to 'end task' the generated report.

Is there a limit to the amount of data that can be fetched using the OLAP feature?

There is always a limit, but what the limit is will highly depend on the webbrowser and your local PC and the capacity of the server.
IMHO a olap on 16000 rows is not the way it should work.

ask your local support what limitations you have to deal with.

Frank is absolutely correct. OLAP relies on the browser and javascript which can both be resource hungry with large amounts of data. Performance drop-off can be dramatic, even though javascript is not over-used by IB. The browser DOM can make accessing large amounts of data very slow.

OLAP is about summarised data that can be used for an easy to digest view of business area performance. 16,000 records does not give the user a chance to digest anything really.

What are you trying to achieve? There may be a better approach to you problem than this.
