Defining Views

Media Database information is displayed on an OS/390 or z/OS console in a format called a "view," using one of three display commands. For more information on the display commands, see the Control‑M/Tape User Guide. The types of views displayed are similar to the display types available through the Inquiry and Update facility. The view definitions reside in member VIEWSDEF in the Control‑M/Tape PARM library.

There is a default view for each of the three Media Database display commands. For more information, see Setting Default Views. The INCONTROL administrator can modify these default views, as well as define and modify optional views. A default view member is provided upon installation of Control‑M/Tape.

The syntax for view definition is as follows:

where

• viewtype is the type of view being defined (for example, a dataset view must display dataset-related fields, and a volume view must display volume-related fields). Valid values are
  • VOLVIEW: The view displays volume-related and volume group-related fields.
  • DSVIEW: The view displays dataset-related fields.
• fieldname is any field that must be displayed in the view. Any number of field names can be specified, separated by commas. For a list of Control‑M/Tape Media Database field names, see Logical Field Names for the Control-M/Tape Repository.
• viewname is a user-defined name assigned to the view.

Examples of defining views:

VOLVIEW VOLSER,VOLFLAGS,VAULTS,NAME=V

VOLVIEW VOLSER,VOLSTAT,NAME=S

VOLVIEW VOLSEQ,NEXTVOL,FIRSTVOL,PREVVOL,NAME=G

DSVIEW  DSNAME,DSVOLSER,VOLSNUM,NAME=D

The views are loaded when Control‑M/Tape is initialized.
