Used by two-phase commit applications to see if a server is prepared to commit a transaction.
prepare tran[saction]
Adaptive Server notifies Component Integration Services when it receives a prepare transaction command so that remote servers involved in the current transaction can enter the prepared state.
For each server that is involved in the current transaction, a prepare command (according to the DTM capabilities of the server) is sent to the server and the results are monitored. If there are no errors reported, each remote server is assumed to be in a prepared state and Component Integration Services returns control to the Adaptive Server. Adaptive Server then enters a prepared state for local work performed by the transaction.
