OnCommand System Manager recieves error 500

Question

Good day, i am running OnCommand System Manager ver 3.1.1 on Windows. Today, for the very first time, i have seen this issue: i can connect to my 3210 running DataONTAP 8.0.3P2 7-mode, but when i try to reach my new 2240 running DataONTAP 8.1.3P3 7-mode i recieve an error 500 "connection refused". I have found this workaround: on the 2240s i have issued the command >options httpd.admin.enable on ;after this the OnCommand System Manager probably still tries a secure connection, on the console i see errors like [hostname: HTTPPool03:warning]: HTTP XML Authentication failed from MyClientIP .  But now i guess OnCommand System Manager falls back to a non secure connection, i see the question "do you want to set up a secure connection or continue without...", i answer "continue without" and i'm able to manage my filers again. What's happened? Maybe something java updates related? Thanks in advance.

While removing newer version of Java and installing older versions probably fixes this in most cases, do you really want to run version of software that have known vulnerabilities in them? I think that companies like NETAPP, EMC, DELL, HP, etc, etc., need to be accountable for staying current.  They need to upgrade the applications regularly to stay compatible with the platforms they develop in.  The days of write it once and forget it are long gone.  The threat vectors have changed and continue to change on a daily basis. If I had machine that was dedicated to doing nothing other managing storage, network and servers, that never saw any portion of the production network and was isolated 100% from the internet, perhaps leaving archaic versions of depreciated software out there would be an option.  The days of doing business this way are also long gone. Cannot speak for everyone of course, but I don’t have the real-estate on my desk and have no desire to run up down the hall to my MDF every time I want to manage something in the environment.
