[jboss-as7-dev] TX subsystem management use cases

[Michael Musgrove]

Can you clarify what it is that you need to know. I don't understand where these attributes are coming from nor what their values mean.

We do have various beans that we have, in the past, exposed via JMX or via RHQ. For example, consider the first attribute "core-environment" =>  .... I guess this is referring to our CoreEnvironment bean which does have a property called socketProcessIdPort which we use to facilitate creation of unique ids and it also has a property called nodeIdentifier which we use to ensure that different recovery managers don't end up recovering each others transactions. But there are also other properties in that bean which your snippet does not mention.

The enable-statistics property simply enables metrics gathering for transaction counts (heuristics, commits etc). Once enabled the statistics can be retrieved from our TxStats MBean.
