Appendix A IPM FAQs and Troubleshooting Tips
Troubleshooting IPM
• (Solaris only) If you change the host name of an IPM system, IPM no longer starts up or works
correctly. To correct this problem, issue the ipm hostname command, then reboot the system.
• (Windows only) To change the IPM Server hostname, you need to update the
IPM_ConfigMain.properties, under IPMROOT\Server\htdocs\webclient directory.
Q.
On the Source Properties window, how is it possible for my system up time to be longer than the
time since the last reboot?
A.
If a source router cannot be reached, or is in the process of rebooting, the Source Properties window
might display an incorrect, backlevel system up time for that router. If the system up time is longer
than the time since the last reboot, wait a few seconds, then refresh the screen to display the correct
system up time.
Q.
Why do I get an error message when I use a host name as a new IP address?
A.
If you get a Host not found error when you use a host name as the new IP address, you must enter
the actual IP address as the new IP address.
In general, you should not use a host name in the
New IP Address field of the Change IP Address
window. It only works if there is a single DNS entry for the device, and if the domain name exactly
matches the one in the database.
Q.
What if I accidentally create a collector that uses all remaining memory in the source router?
A.
The SA Agent in IOS 12.1 or later provides a low-watermark feature to prevent collectors from
using all the memory in the source router. See the Cisco IOS Configuration Fundamentals
Command Reference for details on the rtr low-memory command.
Q.
I have a multi-homed machine. What should I do to make IPM work?
A.
A multi-homed machine is a machine that has multiple NIC cards, each configured with different IP
addresses. To run IPM on a multi-homed machine, there are two requirements:
• All IP addresses must be configured in DNS.
• Because of restrictions in CORBA, only one IP address can be used by the client/browser to
access the server. You must select one IP address as the external address, with which the client
will access the IPM server.
To select an IP address, modify the gatekeeper file ipmgk.props located in
IPMInstallDir/CSCOcwbS/etc(Solaris), or
IPMInstallDir/server/etc(Windows) directory.
Replace every instance of external-IP-address with the external IP address you choose, and remove
the “#” character, from the following:
#vbroker.gatekeeper.backcompat.callback.host=<external-IP-address>
#vbroker.se.exterior.host=<external-IP-address>
#vbroker.se.iiop_tp.host=<external-IP-address>
#vbroker.se.interior.host=<external-IP-address>
Q.
How do I set debug levels of different IPM servers using Message Log server?
A.
At the command prompt, run ipm debug command. IPM launches the message log server.
See the Working With Message Log Window for information about various options available on
Message Log Window.
