Object containers

An object container is a MO:DCA structure that carries object data, which might or might not be defined by a presentation architecture. The required container structure depends on where the object is stored, how it is included in the data set, or both. If the object is stored in a resource library, the object can be included in its unaltered, original form; otherwise, the object must be wrapped with the appropriate MO:DCA container structured fields.

Object container resources are stored in object container libraries in one of these locations:

• Partitioned data sets (PDS or PDSE)

  PSF accesses object container resources in PDS or PDSE libraries specified in the OBJCONDD parameter on the PRINTDEV statement of the PSF startup procedure or the USERLIB parameter on the OUTPUT JCL statement. For more information, see USERLIB.

• UNIX files (HFS or zFS files)

  PSF uses z/OS® UNIX System Services to access data object resources in path libraries specified in the OBJCPATH parameter on the PRINTDEV statement of the PSF startup procedure or the USERPATH parameter on the OUTPUT JCL statement. For more information, see USERPATH.

For more information about specifying the parameters on the PRINTDEV statement, see PSF for z/OS: Customization. For information about the order that PSF uses to search for object container resources, see Searching for resources specified by a print job.
