HA on two machines in Active-Standby mode
Posted:

From glassifsh's HA docs what I could make out is that the servers participating in HA have to be running in lb mode thus mandatorily supporting HA in actiove -active mode.
What if my application can run in active-active mode because of few components facing cynch issues but I still wnat them to be part of HA with other server taking up the responsibility only if one goes down.
To be precise if I have 5 applications(.war) to deploy,3 are to be needed in active-active and 2 in active-stand by mode.
How do I ahieve this, does glassfish support it ?
Regards
Anshul

Hello,
Ensure that your other 2 active-stand by applications are disabled from
being load balanced. Primarily these would be deployed on application
server cluster however, HTTP Load Balancer would treat them as disabled
for load balancing; thus preventing any access to them till these
applications are enabled for load balancing.
While setting up your systems, use asadmin disable-http-lb-application,
and export the load balancer configuration file using asadmin
export-http-lb-config / or using the auto-apply feature to apply the
changes to loadbalancer.
regards
Pankaj

But if I disable the application, how will the failover happen between / active and standby.
And what did you mean by auto apply ?
