Automatic SNAP

The SNAP is activated in automatic mode if the “Automatic Restart” function is active at the time of a system crash and SNAP is set as the dump generator (see the command SET-RESTART-OPTIONS MODE=*ON(..., DUMP=*SNAP)).

Automatic SNAP makes it possible to create a memory dump without operator intervention and then reload the system. Compared to automatic SLED, automatic SNAP has the advantage that the system can be restarted after a short time but that, despite this, the most important diagnostic data is saved.

The SHOW-RESTART-OPTIONS command can be used to output information relating to the control of the automatic restart.
