VMWare conversion....

So.... I am going through a VMWare conversion process at iTouchPoint.   This involves converting legacy app, and sometimes legacy servers, to run under VM's.


It's been a learning experience to say the least.

• Overcommitting memory is fine, so long as you don't end up swapping to a SATA disk :-)
• OpenFiler as an iSCSI device running 3 SATA drives that are short-stroked will give you amazing performance: we're doing > 4000 IOPS, which is all we needed, I don't quite know what this box is capable of
• LAN LAN LAN => iPerf is very useful when it comes to figuring out that your LAN stinks!  200MB/*minute* on a 1GB LAN???? Come on!!!

JBOSS ... nightmares...

So... I decided to use JB 6 for a new project I'm working on, and decided to move over some VERY STABLE code that has been under Spring IoC control.   All I can say is 24+ hours of wasted time later, I decided to give it a shot in GlassFish.  It worked like a charm...

It seems that JB6 has some strange assumptions about activating singletons and EJB injections that do not make sense.... and it was starting up things before dependencies were deployed and then complaining about JNDI resolution failures.

Later on... in the server logs, you can see that it deploys the EJB's in question.  So... I wonder why it couldn't identify the dependencies and deploy them as needed... since GlassFish is able to do it...

Strange...

I Too

Just saw a poem that Annamaria was studying for her reading:

I too, by Langston Hughes
