z/VM: CP Planning and Administration - z/VM - IBM

OPTIONUsageNotesNETRouterspecifies that this user is a network router, and Network Data Transmissionaccount records (type 0C) should be generated for this user. Transmissions toand from a user designated as a router (over a VM LAN), will be reported inaccount records separate from transmissions with non-routers. For moreinformation on Network Data Transmission account records, see “AccountingRecords Network Data Transmissions (Record Type C)” on page 307.NOMDCFSspecifies that the virtual machine can use minidisk cache at a rate that is notlimited by the fair share limit. This allows virtual machines that have a very highI/O rate (such as the shared file system) to get the full benefit of minidiskcache.QUICKDspcauses a virtual machine to be added to the dispatch list immediately when ithas work to do, without waiting in the eligible list.RMCHINFOindicates that the specified virtual machine is authorized to access real-machineconfiguration information, without regard to the virtual machine's configuration. Itshould be used when OSA/SF (or any other application that may require realmachine configuration information) is running under CMS. RMCHINFO shouldnot be specified for guest operating systems.SETORIGspecifies that the virtual machine can issue DIAGNOSE code X'F8' subfunctioncode X'00' to associate originating node and user ID information with a virtualoutput device. For more information about DIAGNOSE code X'F8', see thez/VM: CP Programming Services book.STGEXemptspecifies that the virtual machine is exempt from CP free storage limit detection.This ensures that the machine will not be suspended or forced off if it causesCP to consume too much free storage on its behalf. This option isrecommended for non-general purpose virtual machines.SVC76VMspecifies that errors are not recorded by CP. All guest SVC 76 operations areprocessed by the virtual machine that issued the SVC 76.SVMstatspecifies that the virtual machine is a service virtual machine. The monitor datarecords associated with this virtual machine include the SVMSTAT setting. Theonly purpose is to allow products that process monitor data to report on servicevirtual machines separate from end-user virtual machines. No other operations,such as transaction or wait state classification, are affected by this operand.TODENablespecifies that the user may change the virtual machine’s Time-of-Day (TOD)clock with the SCK instruction or the SET VTOD CP command.1. To run the device support facilities (ICKDSF) program in a virtual machine, youmust specify the MAINTCCW operand.2. The CPU statement overrides the specification on the OPTION statement.3. The LKFAC option must be specified to authorize the user to use the SETLKFAC CP command to join a lock facility I/O configuration.Chapter 17. Creating and Updating a User Directory 537
