Subject Only memory transaction store with JDBC persistence adapter??
Date Fri, 25 Jul 2008 18:34:56 GMT

I'm working on setting up ActiveMQ in a JDBC master/slave topology. It will
also need to participate in XA transactions. When tracing through the code,
I was surprised to see this in the JDBCPersistenceAdapter:

    private MemoryTransactionStore transactionStore;

So when using pure JDBC for message persistence, your only options is an
in-memory transaction store? Maybe I'm missing something, but what good is
it to store prepared XA transactions in memory?

If I'm misinterpreting this, how do I go about setting up a persistent
transaction store while using JDBC message persistence? Or more broadly, how
do I configure ActiveMQ so that I can recover any transactions that have
been prepared in the event of failure?
