The SNAP-ACTIVE-SWITCH=ON/OFF parameter in the startup parameter service specifies whether SNAP is activated immediately in the current session, see the “Introduction to System Administration” [6]. When SNAP-ACTIVE-SWITCH=OFF, SNAP is initially not available for this session. SNAP calls are terminated with a corresponding return code. SNAP can later be activated or deactivated dynamically again as often as required using the ACTIVATE- and DEACTIVATE-SNAPSHOT commands.
The commands for SNAP are described in detail in the “Commands” manual [8].
Command | Meaning |
ACTIVATE-SNAPSHOT | Activates dump generator SNAP |
DEACTIVATE-SNAPSHOT | Deactivates dump generator SNAP |
SHOW-SNAPSHOT-STATUS | Outputs information on SNAP |

The ACTIVATE- and DEACTIVATE-SNAPSHOT commands are executed asynchronously. Message NSP4000 confirms correct acceptance of the command. The SHOW-SNAPSHOT-STATUS command enables you to check the changed settings.
