Adabas Checkpoints

Checkpoint names starting with "SYN"" are reserved for the Adabas nucleus and utilities, as described in:

  • 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 (mainframe only) -- A checkpoint from Adabas Online System (SYSAOS), ADADBS, or the nucleus. The table below identifies the source. 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 (mainframe only) -- 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 (mainframe only) -- A checkpoint made at the beginning of online ADASAV execution (SAVE database function).

  • SYN2 (mainframe only) -- A checkpoint made at the end of online ADASAV execution (SAVE database function).

  • SYN4 (mainframe only) -- A checkpoint made at the beginning of online ADASAV execution (SAVE files operation).

  • SYN5 (mainframe only) -- A checkpoint made at the end of online ADASAV execution (SAVE files operation).

The following table describes the checkpoints written by the Adabas nucleus or utilities:
