Clustering and passive replication
Guys is it possible to build a classic passive replication schema with axis2
clustering support? I mean, only one of the servers actually answers the
client's invocations while the backup replicas "sleep" ?
Thanks in advance,
Igor Nogueira

Hi Igor,
At the moment, a member can only be started in the ACTIVE state. I started
work last week on making it possible to configure a member to be ACTIVE or
PASSIVE in the cluster configuration section. Part of this work is already
available in the trunk. When an active member fails, the coordinator will
activate one of the passive members. Also, the passive member will not start
any transport listeners, hence will not be able to do anything useful until
it is activated. Hopefully, this feature will be available in the next Axis2
release.
Also like Paul said, you can use a Linux HA setup to achieve the same.
Thanks
Azeez

Hi Igor,
At the moment, a member can only be started in the ACTIVE state. I started
work last week on making it possible to configure a member to be ACTIVE or
PASSIVE in the cluster configuration section. Part of this work is already
available in the trunk. When an active member fails, the coordinator will
activate one of the passive members. Also, the passive member will not start
any transport listeners, hence will not be able to do anything useful until
it is activated. Hopefully, this feature will be available in the next Axis2
release.
Also like Paul said, you can use a Linux HA setup to achieve the same.
Thanks
Azeez

Thanks Paul! So, with clustering I can only use active replication, ins't
it?

Igor
Typically you would do this without Axis2 being aware of it - e.g.
either using a Linux IP renegotiation system or Linux HA, or by
setting up your IP sprayer (or mod_proxy) that way.
