Because all software applications occasionally have issues, PMF includes built-in utilities that allow you or your administrator to troubleshoot and resolve potential issues.
If you receive an error that you do not understand, you can enable Application Tracing, then re-run the request that generated the error. If you are proficient in WebFOCUS, you can examine the trace yourself to determine the cause of the issue. If you are not proficient in WebFOCUS, you can forward the trace to either your local support representative or your Information Builders support specialist.
To activate Application Tracing:
The Settings menu opens.
If you selected ON or ALL, tracing is now active. You can re-run any process that has an error message, and select Source from the View menu in your Browser to display the underlying HTML source code containing the error trace. Traces are present at the bottom of the HTML file, after the closing </HTML> tag.
Note: Turning on tracing can slightly lower PMF performance speed because more HTML is downloaded to the browser. It is recommended that you turn off tracing after you resolve the issue you are investigating.
If you encounter errors when using the Visual Discovery Outlier Finder, you can use data tracing to display the data returned from the WebFOCUS server. Application crashes and other anomalies in Visual Discovery are the result of errors in data retrieval. The most common error is caused by an incorrectly configured web server tier.
To activate Tracing in the Visual Discovery Outlier Finder:
The Outlier Finder interface appears.
PMF displays a data trace showing the URL query string that was issued to the server, and any data that was retrieved.
If no records are retrieved, check to make sure the dimensional, measure, or objective intersection actually has data. Also check the URL and ensure there are no errors there. If you notice an error at the start of the query string, such as an invalid web server name or port, you can correct these by editing the A_HOSTNAME.FEX procedure in the \ibi\apps\pmfdata folder on your WebFOCUS Reporting Server. This file should contain the following string:
-SET &HOSTNAME = webserver_name[:port]
After you have corrected the issue, re-run the page in Trace mode and verify that you are receiving data. You can then clear the Trace check box and confirm that Visual Discovery is working.
