By definition :
A logical point in the execution of an application program where the changes made by the program are consistent and complete, and can be committed. The output, which has been held up to that point, is sent to its destination, the input is removed from the message queues, and updates are made available to other applications. When a program terminates abnormally, CICS recovery and restart facilities do not back out updates prior to the last completed sync point.
The beginning or ending of a unit of recovery when all resources are consistent.
An intermediate or end point during processing of a transaction at which the transaction's protected resources are consistent. At a syncpoint, changes to the resources can safely be committed, or they can be backed out to the previous syncpoint.
A place in a program (specified by a command or a condition) where the system stops the processing of that program and gives control to the display station user or to a specified program.
A point at which the database manager records internal status information on the log; the recovery process uses this information if the subsystem abnormally terminates.
