Commit or roll back the action of the [b]Compute node [/b]on the database depends on the success or failure of the entire message flow.

Is the above statement is true for JavaComputeNode?

If there is a failure after the message is propagated to out terminal of JCN(Performs database insert) , the data is rolled back or not.

It depends on what you do to establish a database connection.

There's documentation on the right way to do this.
