The following checkpoints are written by the Adabas utilities:
- SYNC
A checkpoint made during nucleus initialization, termination or cancel processing; during the ADAOPR function FEOF = PLOG; due to ADABCK NEW_PLOG processing; or during the function ADAOPR EXT_BACKUP=CONTINUE.
- SYNP
A checkpoint made by a utility that requires privileged control. Such utilities can perform updating without using the Adabas nucleus.
- SYNX
A checkpoint made by a utility that requires exclusive control (EXF) of one or more files.
The following tables shows which utilities or utility functions write which checkpoints. Where appropriate, information about the online/offline status of the database is also provided.
| Utility | Utility Function | Checkpoint | Database Online/Offline, Comments |
|---|---|---|---|
| ADABCK | DUMP | SYNX |
The nucleus is only required when there is an AUTORESTART pending at the end of this function. |
| EXU_DUMP | SYNC |
The nucleus is only required when there is an AUTORESTART pending at the end of this function. |
|
| OVERLAY | SYNP |
The nucleus must NOT be active for overlay of the database or system files. The nucleus is not required for overlay of files. |
|
| RESTORE | SYNP |
The nucleus must NOT be active for restore of the database or system files. The nucleus is not required for restore of files. |
