Package running as master/slave

Tulio Magno — Tue, 08 Jun 2010 14:07:06 GMT

I'd like to know if it is possible to run a custom package as master/slave on Serviceguard.

In example: I have n nodes running the same package but one of them is set as master and has a relocatable IP address. The others are slaves. If the master fails, one of the slaves will become the master.

I don't think it is possible to create this using failover or multi-node packages. Am I correct?

Shalom Tulio,

If the database is actually open at all times, you might want to design a special package to handle floating IP addresses.

If you set priority on them, you can load balance your application traffic.

I think multi-node packages is the way to go.

Hello Steven,

Thank you for your answer.
In this scenario it is necessary to configure a failover package with the relocatable IP address only?

right, if you want the 'master' to have the relocatable.. configure a pkg with the IP to failover to node x if the master node dies.
