Re: Auto Set unique.instanceId

[Jacques Le Roux]

Hi Sam,

I'm not sure to get it but you could use the IP address of each machine, look 
into startofbiz.sh:
IPADDR=`/sbin/ifconfig eth0 | grep 'inet addr:' | cut -d: -f2 | awk '{ print 
$1}'`

From that you could parse (ie remove the dot) and create an unique Id for each 
machine

Also Googled for "sh properties file access", found this as 2nd entry in the SERP http://shrubbery.mynetgear.net/c/display/W/Reading+Java-style+Properties+Files+with+Shell

Hey everyone!

This is kinda a weird question but does anyone know a way to auto insert the 
machines hostname in the unique.instanceId variable
in general.properties?

I am asking as I am migrating over to AWS and trying to automate the build for 
a whole clustered stack so that if one of the
instances dies the system knows and rebuilds.

Something like unique.instanceId=$HOSTNAME but I don't know where to find the 
supported list of variables that a properties file
can have?


Cheers
