create_object

create object(1m)														 create object(1m)

NAME

       create object - Creates an object entry

SYNOPSIS

       cdscp create object object-name [CDS_Class = class-name CDS_ClassVersion = value]

ARGUMENTS

       The  full name of the object entry.  The class of object entry being created. You can specify an application-defined class name. A class is
       specified as a simple name limited to 31 characters.  The version of the class assigned to the object entry.  Specify  the  value  as  v.n,
       where  v  defines the major release number and n specifies the minor version number.  Specifying a class version is useful as it allows the
       definition of a class to evolve as the application is revised.

DESCRIPTION

       The create object command creates an object entry. This task is usually done through a client application.

   Privilege Required
       You must have insert permission to the parent directory.

NOTE

       This command is replaced at Revision 1.1 by the dcecp command and may not be provided in future releases of DCE.

EXAMPLE

       The following command creates an object entry named /.:/sales/east/floor1cp. The object entry describes a color printer on the first  floor
       of a company's eastern sales office.  cdscp> create object /.:/sales/east/floor1cp CDS_Class = printer CDS_ClassVersion = 1.0

RELATED INFORMATION

       Commands: delete object(1m), list object(1m), set object(1m), show object(1m)
