Currently I am working on HA and I have a query regarding
the presence of subscription.xml in the distributed machine.
When I bring down the Master's Registrar down (pls note
that Distributed Registrar up), the replication of registration.xml
stops on Master. At this stage, all the registrations record
(registration.xml) will be held by Distributed machine as expected. The
registration.xml in the Distributed machine gets updated accordingly
with corresponding expires. But the subscription.xml in distributed
machine does not get replicated once the master registrar goes down. Pls
note that the subscription.xml under the Master got updated with
unexpired subscriptions. IOW the subscriptions continue to exist in the
HA environment even with one of the registrars down. This makes me think
of the reason why subcription.xml need to be present in the distributed
machine. And if at all present what is the use of it, when for all the
transactions the subcription.xml in Master is referred.
registration.xml and subscription.xml are handled very differently.
Information about registrations is replicated between the Master and
Distributed registrars, so the contents of the two registration.xml
files are normally the same.
Information about subscriptions is *not* replicated between the Master
and Distributed machines. Each subscription served by a particular
component on a particular machine is recorded in that machine's
subscription.xml. If that component fails, the subscription is not
taken over by a component on another machine. Although if that
component is restarted on that machine, it will resume serving the
But what Sathya found was that the subscriptions are getting replicated
and her question was
"Why is this replication required at all" ?
