Re: ActiveMQ locking mechanism and data on unique database data sources

[Vince Cox <VC...@perforce.com>]

Tim,

Are you aware of ActiveMQ moving towards using a bulkhead pattern?

Thank you.

    Tim,

    Since they have experienced such an issue with leader election, they are requesting implementing a bulk head pattern to increase the resiliency of ActiveMQ

        I understand your point of view completely. I have a customer that runs Oracle. When they have moderate traffic they experience a failover event between the Master/Slave. And it appears to come from an inability to access the lock in time causing the slave to take over. When they first came to us, we wondered why they wanted to do this as well.

            To confirm, are you saying that you're trying to use one Oracle database
            for message storage and a different Oracle database for locking?

            If so, would you mind explaining why you're not just using a single
            database for both purposes? I have no idea if the configuration I think
            you're describing is possible in the current implementation, but I could
            imagine someone saying that there was no need to support it because no one
            would ever use it since they'd never want multiple SQL databases vs. using
            a single database for both purposes, and I'd like to understand why that
            assumption is a bad one.
