Solved: Changing the hostname

DanR. · ‎Apr 14, 2015

I'm creating a plan to upgrade our MKS Integrity 2009 SP7 (AIX) test server to PTC Integrity 10.6 (AIX). In the is.properties file there is a setting mksis.hostname=mks-test.

Server URL is http://mks-test:7001. The actual name of the server is something different. I changed the hostname setting in the is.properties file to ptc-test. I stopped ans started the server using mksis stop and mksis start and I saw errors in the server.log:

2015-04-14 07:33:20,103 DEBUG [mksis.IntegrityServer] DEBUG(0): mks.frame.client.ConnectionException -- mks.frame.client.ConnectionException: MKS124871: Could not establish server connection (it may be down). Details: Error resolving hostnames; nested exception is: java.net.UnknownHostException: ptc-test

What did I miss?

Daniel,

This error suggests that there is no DNS entry for "ptc-test" to be mapped to any IP address at all. You will need to discuss having this entry created with your network administrator. The only alternative is to use a local HOSTS file, but this is very cumbersome.

Changing the value of mksis.hostname will also require using a diagnostic (at the very least) to re-map existing change packages within the database to a different mksis.hostname value. Please see https://support.ptc.com/appserver/cs/view/solution.jsp?n=CS172703 There are also certain steps in the following article https://support.ptc.com/appserver/cs/view/solution.jsp?n=CS115211&lang=en_US that I would suggest reading over as well, namely step 8 and 9.

I would suggest opening a case with support so we can help with any additional scope of changes for this server.

Did the server start although there is this error in the log file?

Is the new server name reachable from the client (e.g. "ping potc-test") ?

No. The server.log repeats the error every 5 seconds. The client reports this error -> "Error connecting to ptc-test:7001 (it may be down): The IP address of the host could not be determined"

We are not moving the server to new hardware. And we are not using change packages at this time.

I opened a case.
