Windchill 503 Service Unavailable

I am having a Windchill error when I try to access the database.  The PTC logo comes up but then it times out and says "Service Unavailable".  The Windchill database is on a server and I am accessing from my PC.  We recently had a new security router installed and the IP addresses were changed.  I think this could be part of the issue but I can't find where to fix it.  If I go to the Apache server name in my browser I get the "It Works!" message.  But the log files in Windchill show the method server is not connecting.  I don't know how to fix this.  I have updated the httpd.conf file in the Apache setup folder to show the new IP but it didn't help.

 

Can someone please help?

@mmeadows-3 is correct: I've been able to resolve IP issues by putting an entry in the hosts table:

 

<IP address> <Fully qualified longname with domain> <shortname>

Hi,

 

Windchill isn't ready until you see something like this in the methodServer log:

main: INFO  : wt.method.server.startup  - MethodServer ready (in 704.283 secs).

If you don't see anything like that, work backwards through the log and there should be some reason, a java error, database problem, etc.

 

Examples of typical issues I have seen:

-There is an incorrect entry for the server in the server's hosts table; or something like this
-The database transaction log is full
-Some other database issue, however full trans log is pretty common.

 

Not sure about changing IP addresses in httpd.conf.  Not a normal thing I've had to do.  Also somewhat confused about just what/where the IP addresses changed.....? On the router, or on the server(s)?

 

The Methodserver log is the place to start.

 

Hope this helps!

Thank you.  I will try to dig deeper into the log files.

Is there a folder that holds the database transaction logs that I need to clear out?  I cleared the log files in the Windchill folder when I started this.

 

Yes, the IP addresses for the server changed.  So I was concerned there was a link somewhere in the system setup that called for the server to connect to that specific IP, in which case I would need to update it.

Did you check the Windchill server's hosts file? Implementation specialists commonly hard code IP addresses in the hosts file so Windchill won't crash if/when the DNS server hiccups.

    I don't think I have checked that one.  Where do I find this host file?
