KEY phrase
relationship
If position is present, relationship is limited to:
position
NOTE: BEFORE is available only for the ECOBOL compiler.
STARTBACKUP
NOTE: Do not use this directive in the OSS environment.
options
The fault-tolerant facility is to read and process system messages, and the primary process is to terminate
abnormally if a trap condition occurs.
0
Same as option 0 except that if the primary process stops, the backup process takes over processing
of the application.
1
Same as option 1 except that if the primary process encounters a trap condition, it enters the DEBUG
procedure instead of being terminated abnormally.
2
The primary process, rather than the fault-tolerant facility, reads the $RECEIVE file and takes appropriate
action for system messages. In addition, if the primary process encounters a trap condition, it enters
3
the DEBUG procedure. When this option is in force and the backup process fails, the primary process
must re-execute the STARTBACKUP statement to reestablish the backup.
