System and Other Functions$ZUTIL(69,20)Transfers global nodes with null subscripts with DSM-DDP.$ZUTIL(69,20,n)$ZU(69,20,n)ParametersnThe boolean value that specifies whether the network allows null subscripts.DescriptionWith Open M [DSM]-DDP networking, you can transfer global nodes that include null subscripts.$ZUTIL(69,20) controls this ability system-wide.When enabled (n=1), Caché can read and write global data with null subscripts across a networkconnection. When disabled (n=0), all data with null subscripts is effectively invisible,and all references to such data generate errors. The default is disabled (0).This setting only applies to DCP networks. On ECP, null subscripts are always allowed overthe network.Invoking $ZUTIL(69,20) without specifying n returns the current switch setting.Setting $ZUTIL(69,20) overrides the default system-wide; it does not change the systemconfiguration setting. This configuration default cannot be changed using the System ManagementPortal.ParametersnThe switch that controls whether Caché can transfer null-subscripted global nodes throughOpen M [DSM]-DDP. 0 = Disables system-wide transfer of null-subscript nodes. 1 = Enablessystem-wide transfer of null-subscripted nodes.By default, the ability to transfer null-subscripted globals is disabled. You cannot control thisswitch on a process level.For further details on subscripted globals, see Global Structure in Using Caché Multi-Dimensional Storage.654 Caché ObjectScript Reference

Every TCOMMIT command requests a flush of the journal data involved in thattransaction to disk. When $ZUTIL(69,21) is enabled (set to 1) a TCOMMIT does notcomplete until the journal data write operation completes. When set to 0, TCOMMIT doesnot wait for the write operation to complete. Setting $ZUTIL(69,21) changes the systemconfiguration setting and is persistent across Caché shutdowns and startups.Invoking $ZUTIL(69,21) without specifying n returns the current switch setting.This system configuration setting can also be changed using the System Management Portal.Select Configuration, then select Advanced Settings. On the pull-down Category list selectTransactions. View and edit the current setting of SynchronousCommit. The default is “false”.You can also disable or enable this mode on a per-process basis. See $ZUTIL(68,21).ParametersnThe boolean switch that determines the system-wide default mode for synchronous transactioncommit: 0 = TCOMMIT completion does not wait for journal file write completion. 1 =Caché ObjectScript Reference 655
