In cases where a Cognos report is to be used as a dashboard, an auto refresh capability in the report is required to load the data automatically at specific intervals without human intervention.
Following are the high level instructions on how to achieve it. A link to the detailed document is provided below.
- For all the queries in the report, set the property Use Local Cache to No.
- Add a HTML item at the top of the report and add the following meta tag in it.
<meta http-equiv="refresh" content="5">
This will refresh the report every 5 seconds. Content attribute is in seconds. You cn set it as per your requirement
- If you have loaded the Cognos report into a Tivoli Integrated Portal dashboard, then set the session timeout value to not expire for the application server on which Tivoli Common Reporting is running.
