NetWeaver Cluster Management

[Former Member]

Hi everybody,

We are using NetWeaver CE 7.1 in a cluster environment. Our intention is to receive notifications if some cluster event occurs, like: a new node was started, a node was stopped, the cluster was split.

Is it possible to use JMX to get status information about NetWeaver cluster?

Are there some MBeans which manage the Cluster?

Thanks in advance,

Radu

Hi Radu,

first of all, the management console does do that. But there is also documentatio9n about how to use JMX:

Hi Benny,

Thanks for your quickly answer.

We need to implement some failover strategy for our singleton services deployed in a NetWeaver cluster. Therefore we have to receive, if this is possible, some notifications from the cluster infrastructure of NetWeaver. The failover will be implemented by our application, which decides on which node the new singleton service instance will be started.

We want to reuse the cluster management infrastructure of NetWeaver to get the u201Ccurrent viewu201D of the cluster status and to receive notifications if, for example, a node leaves the cluster.

If this is not possible, we have to port our own cluster management infrastructure to NetWeaver. This means that we would deploy our proprietary cluster communication layer which will run in parallel with the NetWeaver cluster communication layer.

Simply said, we need to get the same information like the telnet LSC command, but augmented with notifications.
