Doc Text:
In previous versions of JBoss EAP 6, changes to the object store type (from HornetQ to JDBC, or vice versa) through the CLI interface were not propagated correctly. As a result, the object store would remain as initially set (which may have been the less desired option). In this release the write handlers 'use-hornetq-store' and 'use-jdbc-store' have been enhanced to disable the other option when used and the object store used is always the chosen option.

Description Ondrej Chaloupka 2013-12-06 10:16:30 UTC 
When you have set the object store to be type of hornetq and then you change your mind to set it for jdbc object store the jboss-cli permits this operation but no change is propagated to model and XML file.

How to reproduce:
1) ./bin/standalone.xml (start eap 6.2.0.GA)
2) ./bin/jboss-cli.sh -c (connect to running eap)
2a) /subsystem=transactions:write-attribute(name=use-hornetq-store, value=true)
2b) :reload
2c) /subsystem=transactions/log-store=log-store:read-attribute(name=type)
2d) /subsystem=transactions:write-attribute(name=use-jdbc-store, value=true)
2e) :reload
2f) /subsystem=transactions/log-store=log-store:read-attribute(name=type)
 The object store stays to be set to hornetq and no change happens in the standalone.xml file.

You need to disable 'use-hornetq-store' first as TransactionSubsystemXMLPersister prefers the hornetq store to the jdbc store, see the code snippet below:

if(node.hasDefined(CommonAttributes.USEHORNETQSTORE) && node.get(CommonAttributes.USEHORNETQSTORE).asBoolean()) {
..
} else if (node.hasDefined(CommonAttributes.USE_JDBC_STORE) && node.get(CommonAttributes.USE_JDBC_STORE).asBoolean()) {
..
}

Other possibility would be to enhance 'use-hornetq-store' and 'use-jdbc-store' write handlers to disable the opposite option.

The workaround for this is to change the other attribute before reloading, probably best to do it in a batch.

Ok, it works for me now. Checked on EAP 6.3.0.ER1.
Thank you.
