Appendix A IPM FAQs and Troubleshooting Tips

Troubleshooting IPM

If this situation occurs in your configuration, you must remove the old target or source from the database, as well as any IP Path Echo collectors that use the old target or source as an intermediate hop, then add the collectors back to your configuration.

Q.I am unable to launch the web client, and I get a Java console error message: “Reason = hostname is not DNS resolvable.” What should I do?

A.This is because the DNS name in the IPM_ConfigMain.properties cannot be resolved on the client side. To correct this, change:

hostName=hostname to

hostName=IP Address

Q.In the logs, I see the message “Unable to get version.” What does this mean?

A.This could be because of one of the following reasons:

•Router down/unreachable at that time.

•Community strings were changed, and the IPM database was not updated.

•IP address was changed, and the IPM database not updated.

•This error message can be either for the source or from the target.

Q.When I launch the IPM web client on Internet Explorer, I get the following message, and the web client does not launch: “Your current settings prohibit running ActiveX controls on this page. As a result, the page may not be displayed correctly.”What should I do?

A.Add the IPM Server as a trusted site on Internet Explorer. Once you have added IPM Server as a trusted site, the problem goes away. For more information, access the Microsoft site: http://support.microsoft.com.?id=816702.

Q.I have changed the date and time of my machine where I have installed the IPM Server. Do I need to restart IPM?

A.Yes. When you change the date and time of the IPM Server, you need to restart IPM. Else, IPM uses the old time and date in reports.
