In OpenEdge 10 and 11 versions:OpenEdge Management is a web application hosted in the Jetty Web Server. This Jetty web server is hosted as a plugin to the AdminServer.
The AdminSever connects through the Jetty WebServer HTTP Listener Port (default=9090) which will need to be changed when remote monitoring of other versions is not used.
The default http listener port is 9090. Its value can be changed by editing the
fathom.properties file and restarting the AdminServer.
- OpenEdge 10.1C and 10.2A : {OEE | OEM installation directory}\config\fathom.properties
- OpenEdge 10.2B and 11 : {DLC OpenEdge installation directory}\properties\fathom.properties
If OpenEdge Explorer (OEE) or OpenEdge Management (OEM) has never previously been started, the fathom.properties file will not show an entry for the http port as this is updated in the fathom.properties file as part of the initialization screens at first login, otherwise it will already have the default port:9090 tailored unless otherwise specified during the initialization tailoring.
To change the default http listener port:Edit the
[webserver] Section in the fathom.properties file, to change the port number to the required port available:
[webserver]
httpenabled=true
httpport=<newPortHere>
Save the file and restart the AdminServer.
In OpenEdge 12 - OEM is installed as a standalone web application running in a Tomcat.
Since OpenEdge 12.0 OEM/OEE is no longer a self-hosted web application running as a part of the AdminServer, it has been converted to a pure web application running in Tomcat. The OEM/OEE (fathom.plugin) has been abstracted from the AdminServer and is exposed as a webapp running on a PASOE instance which uses the tomcat http(s) listener port. As such there is no longer the need to that enable (glue) and disable (unglue) OEM functionality. The OEM install directory is effectively the directory of a deployed PAS instance
The http(s) listener port used by the OpenEdge Management/Explorer webinterface can be found under "port #s used by server.xml"
in:
- {OEE | OEM installation directory}\conf\catalina.properties
psc.as.http.port=9090
psc.as.https.port=9443
Restart the PASOE instance:
1. Windows restart the service "OpenEdge Management Service for OpenEdge".
2. From the commandline with pasman or tcman
$OEM/bin/tcman service start (on windows)
$OEM/bin/tcman start (if not service, if not on windows)
Update the URL:
- Modify the OpenEdge Console Browser address accordingly eg: http://<host>:<newPortHere>
- Modify the fathom.url to reflect the updated url port.
The fathom.url file is located in the OpenEdge installation and/or the OpenEdge Management (OEM) / OpenEdge Explorer (OEE) installation path (depending upon the OpenEdge version).
Example: Pre-OpenEdge 10.2B the fathom.url file is located in OpenEdge installation path.
Post-OpenEdge 10.2B, 11, 12: the fathom.url file is located in OpenEdge Management/Explorer installation path.
