Caché ObjectScript Reference - InterSystems Documentation

System and Other FunctionsParametersnA boolean switch that determines whether Caché allows the processes to kill root-level globalnodes: 0 = Root-level global node kills are allowed. 1 = Root-level global node kills are notallowed.The default for the system is zero (0). This means that killing a root-level node does notgenerate an error. For example, you can execute the following without an error:KILL ^aYou can determine the current state of the switch by issuing $ZUTIL(69,28). You can setthe switch for the system so that root-level global node kills are not allowed by issuing$ZUTIL(69,28,1). After you set the switch, any attempt to kill a root-level node generatesa error. For details on error format, refer to the $ZERRORspecial variable.NotesThis configuration default cannot be changed using the System Management Portal.Setting $ZUTIL(69,28) overrides the System Configuration default; it does not change thedefault setting.Any change you make with $ZUTIL(69,28) affects only processes that log in after you issue$ZUTIL(69,28). That is, if you issue $ZUTIL(69,28,1), only processes that log in after thefunction call was issued generate errors when attempts are made to kill rootlevelnodes. Processes that logged in before you issued $ZUTIL(69,28) can still kill rootlevelnodes.You can also disable or enable this mode on a per-job and per-device basis. For informationon setting this for a job, see $ZUTIL(68,28) Control Root (Unsubscripted) Node Kills.For further details on subscripted global nodes, see Global Structure in Using Caché Multi-Dimensional Storage.See Also• $ZUTIL(68,28) Control Root (Unsubscripted) Node Kills function• KILL command662 Caché ObjectScript Reference
