In domain mode, it should be possible to start two nodes, each belonging to a different site and get them to join the inter-site cluster providing a single profile.
To be able to do that, the following needs to happen:
- A cache's backup site name needs to be able to be defined via a system property, e.g.
<backups>
<backup site="${test.site.local.name:NA}" strategy="SYNC"/>
</backups>
- A jgroup stack's relay remote site name needs to be able to be defined via a system property, e.g.
<relay site="${test.site.local.name:NA}"> <remote-site name="${test.site.remote.name:NA}" channel="xsite"/> </relay>
With these changes, it should be possible to define a single profile, and then override site local and remote names via system properties, e.g.
<server-group name="site-earth" profile="clustered"> <jvm name="default"> <heap size="64m" max-size="512m"/> <jvm-options> <option value="-Djgroups.join_timeout=1000"/> <option value="-Djboss.default.multicast.address=234.99.74.14"/> <option value="-Dtest.site.local.name=EARTH"/> <option value="-Dtest.site.remote.name=MOON"/> </jvm-options> </jvm> <socket-binding-group ref="xsite-sockets"/> </server-group> <server-group name="site-moon" profile="clustered"> <jvm name="default"> <heap size="64m" max-size="512m"/> <jvm-options> <option value="-Djgroups.join_timeout=1000"/> <option value="-Djboss.default.multicast.address=234.99.74.24"/> <option value="-Dtest.site.local.name=MOON"/> <option value="-Dtest.site.remote.name=EARTH"/> </jvm-options> </jvm> <socket-binding-group ref="xsite-sockets"/> </server-group>
Right now no system property substitution happens for the elements above and hence it's not possible to achieve this with a single profile. Instead, profiles need to be duplicated making it hard to maintain.
