I manage several different instances of ColdFusion on several different physical servers. Each instance has its own CF administrator running under JRun's built in web server and while I have each bookmarked, I often forget which port number belongs to which instance on any given server. To help me identify which instance I'm currently working in I put together this basic instance identifier for the CF administrator. Just download the attached serverinstance.cfm and place it in your CFIDE/administrator directory. If you have an existing extensionscustom.cfm file in your administrator directory just add the following link:
If you don't have an extensionscustom.cfm file in the CFIDE/administrator directory create one with the above content.
When you log in to the CF Administrator you should now have a "Server Instance" link under "CUSTOM EXTENSIONS" in the left hand navigation frame. Click on the link to bring up a page identifying the JRun instance.
