the other servers to get the outcome of the transactions. If the other servers are unreachable, the

To set a transaction timeout value
By default, the server does not timeout a transaction. That is, the server waits indenitely for a
transaction to complete. If you set a timeout value for transactions, if a transaction isn’t
completed within the congured time, the Enterprise Server rolls back the transaction.
In the tree component, select the Congurations node.
