deadlock
Deadly embrace, a situation that occurs when two transactions
or parts of transactions conflict with each other, which could
violate the consistency ACID property when committing them to
the database.
disk shadowing
A process by which identical data are written to multiple disks to
increase data availability in the event of a disk failure. Used in
a cluster environment to replicate entire disks or disk volumes.
See also transactional shadowing.
dispatch
A method in the C++ API RTRData class which, when called,
interprets the contents on the RTRData object and calls an
appropriate handler to process the data. The handler chosen to
process the data is the handler registered with the transaction
controller. This method is used with the event-driven receive
model.
DTC
Microsoft Distributed Transaction Coordinator.
endian
The byte-ordering of multibyte values. Big endian: high-order
byte at starting address; little endian: low-order byte at starting
address.
event
RTR or application-generated information about an application
or RTR.
event driven
A processing model in which the application receives messages
and events by registering handlers with the transaction
controller. These handlers are derived from the C++ foundation
class message and event-handler classes.
event handler
A C++ API-derived object used in event-driven processing that
processes events.
