After also putting in a ticket to Oracle (and getting nowhere) - I tried looking at all the tools that come with Server Manager. Evidently the port 1450x stream is a JMX stream - and I even downloaded the sun JDK so I could run jconsole. Unfortunately it doesn't connect.
I thought I had a bit of a brainstorm earlier - whereas I used the server manager monitors to output the information to a file by creating a "monitor" and putting the threshold to 1 - which seemed to work as soon as I went OVER 1 - but then the monitor seems to just stop monitoring. I even clicked "autostart". That would have worked for me, because the monitor creates an XML file on the Server Manager server (in our case, the deployment server) which I can parse using a script. I'm hesitant putting in yet another ticket before exploring other avenues.
I even tried using OPMNCTL with the "status" and different options. Not much use there - since that only queries what servers are running.
Lastly, I found something called "EMCLI" - but I think this might have something to do with the original Enterprise Manager under earlier OAS versions. Also, looking to see what users are connected through OAS directly is NOT a reliable figure.
I know I can use WGET to "get" the web page from the server manager into a file, then use AWK or something similar to parse out the information - but thats quite messy, and I really wanted a simple query command...
If anyone knows how to do this, I'd appreciate it ! Alex - if you can get a tool in place that can send instructions from the command line to the server manager - that'd be TOTALLY valuable...we'd be able to schedule startup of JVM's, disable users, query information - a whole host of stuff !
Oracle is usually big into command line tools. I'm a little disappointed that the Server Manager developers don't subscribe to the same mentality. Us "techies" like command line !
