jBoss on OpenVMS

[Kristen Harum]

Anyone who can help me out?

I run VMS 7.3-2 on an Alpha server.

I've installed the required VMS patches and the Java SDK itself; seems OK so far: Java virtual machine responds as on othe platforms.

jBoss claim they're platform independent, which is probably right but som nuts and bolts are missing since their delivered kit comprises Windows and Unix command scripts only.

Anyone who have done this job already with OpenVMS?

Not yet, have been thinking to, so I'm willing to cooperate.
However, a word of warning.
AFAIK, JBOSS is a JAVA application - what means it may run on OpenVMS, AND it will require a lot of CPU power and huge amounts of memory. You will surely need to adjust your system parameters to accomodate JAVA applications, and that may interfere with other settings or just contradict "good system management practices".
Futhermore, there may be issues with java that make it unusable on VMS. Some code simply won't run on VMS - see the JAVA release notes.

Not just read them, I applied them as well. My system is MINIMAL (in memory) so it's obvious that I need huge pagefile(s) - and still have to suffer low performance - up to haning systems (due to pagefile exhaustion).
All I have been told to do is "Buy more memory" which, is both impossible (both cost and hardware problems) and ridiculous - I think it too bad that I have to adapt a system to faciliate a badly behaving product, by that bypassing what I (and others) condsider good practice.
Therefore: if you can avoid Java, do so.

You need to create OpenVMS specific DCL-scripts for startup and shutdown (detached process).
I had problems with the 4.x something versions with SNMP services. Just removed those from configuration, then it worked fine.
And yes, You will need an Alpha or Itanium server with at least 1Gb memory (more is better).
