first of all it would be helpful to know which Operating Systems we're talking about.
Apologies! The app server is running on Windows 2008.
No Problem Mike
Well I think, the easiest way is to check where BladeLogic is installed - "C:\Program Files" or "C:\Program Files(x86)". Of course, this is only helpful, if you're using this directories. Otherwise, I'm not sure, but isn't there a notice in the appwizard?
Unfortunately the install dir is root on a drive :/
The only version info that blasadmin gives is Bladelogic Admin Utility; Version 126.96.36.1991. Seems ridiculous that it doesn't tell you!
Well, I'm not 100% sure, but in the appserver.log, which resides under ...\br, somewhere in the first lines, there must be a notice which indicates the version. In my Linux Appserverr.log it looks like this:
OS Name = Linux
Version = 2.6.18-194.32.1.el5
Architecture = amd64
Number of Processors Available to JVM = 2
JRE Version = 1.6.0_13 from Sun Microsystems Inc.
JRE Data Model = 64-bit
JRE VM Name = Java HotSpot(TM) 64-Bit Server VM
Maximum JVM Memory (B) = 1,698,234,368
Total JVM Memory (B) = 315,555,840
Free JVM Memory (B) = 129,521,072
Used JVM Memory (B) = 186,034,768
Maximum File Descriptors = 1,024
Used File Descriptors = 282
FIPS 140-2 Mode = enabled
BLManager Current Time = Mon Sep 05 10:13:16 GMT+00:00 2011
BLManager Started = Mon Sep 05 10:13:03 GMT+00:00 2011
BLManager PID = 11943
Just check this file, but choose the right one, because this informations are only shown during appserver startup, and there is usually more than just one appserver log.
In my eyes, JRE Data Model = 64-bit indicates, that you're using 64bit, because Java is usually installed through the BL Appserver installer, but I cannot guarantee.
I can see that JRE Data Model = 64-bit in our logs. Seems the best bet
The best way to find out is to check under the infrastructure management. You will need BLAdmins level role to see this.
Go to Tools- Administration- Infrastructure Management
Check under Application Servers, select your appserver, and you will find all the details here including the architecure and the JRE/JVM details as well.
