CP-NAME is the checkpoint identifier. In the case of a user non-synchronized checkpoint, this is the checkpoint identifier supplied by the user program. Checkpoint names starting with "SYN"" are reserved for the Adabas nucleus and utilities:
SYNC -- A synchronized checkpoint made during nucleus initialization, including the status of the ADARUN IGNDIB and FORCE parameters.
SYNF -- A checkpoint taken by a user program or utility that requires exclusive (EXF) control of one or more files.
SYNP -- A checkpoint from a utility that requires privileged control. Such a utility can perform updating without using the Adabas nucleus.
SYNS -- A checkpoint from Adabas Online System (SYSAOS) or ADADBS with three exceptions from the nucleus. The function identified by this checkpoint is implemented without user intervention during regeneration.
Exceptions include a second SYNS 5B recorded at the end of a nucleus session, SYNS 60 recorded at an interval specified by the ADARUN INTNAS parameter, and SYNS 61 recorded when more space is allocated for a file.
SYNV -- Indicates that a volume ID changed during sequential write to a data set is being closed.
SYNX -- A checkpoint from a utility requiring exclusive control (EXU) of one or more files.
SYN1 -- A checkpoint made at the beginning of online ADASAV execution (SAVE database function).
SYN2 -- A checkpoint made at the end of online ADASAV execution (SAVE database function).
SYN4 -- A checkpoint made at the beginning of online ADASAV execution (SAVE files operation).
SYN5 -- A checkpoint made at the end of online ADASAV execution (SAVE files operation).
