Subject [jira] Commented: (AMQNET-290) Add an API model to NMS that allows providers to participate in Distributed Transactions.
Date Mon, 25 Oct 2010 21:08:40 GMT

    [ https://issues.apache.org/activemq/browse/AMQNET-290?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=62817#action_62817
] 

Timothy Bish commented on AMQNET-290:
-------------------------------------

Things are a bit tricky on .NET in that the System.Transactions classes can be in Local or
Distributed mode depending on the configuration of the client.  For distributed transactions
we really need to be able to map the DTC id's into Xid's but MS seems to have made this pretty
tough in .NET.  When in local mode what should we do, just play nice and use standard local
transactions or refuse to play altogether.  This implies that we'd have to manage the enlistment
though since in local mode we can't do recovery so we'd have to be sure we are enlisted as
volatile.

> Currently the NMS API doesn't define any way for the client to participate in distributed
transactions.  The JMS model allows a for this using the Java XA transactions.  The JMS API
defines an XAConnectionFactory, XAConnection, and XASession that provide the needed bits to
interact with a Transaction Manager.
> We should provide something similar in NMS that allows for a provider library like NMS.ActiveMQ
to be used in distributed transactions in .NET most likely using the MSDTC.  The API could
expose an IEnlistmentNotification implementation that allows the client to enlist the Transaction
in a DTC controlled transaction as a Resource Manager.
