The Delete Media Definition (DLTMEDDFN) command deletes the specified media definitions from the system.

Restrictions:

• You must have object existence (*OBJEXIST) authority for the media definition and execute (*EXECUTE) authority for the library where the media definition is located.

Parameters

Keyword	Description	Choices	Notes
MEDDFN	Media definition	Qualified object name	Required, Positional 1
	Qualifier 1: Media definition	Generic name, name
	Qualifier 2: Library	Name, *LIBL, *CURLIB, *USRLIBL, *ALL, *ALLUSR

Media definition (MEDDFN)

Specifies the media definitions to be deleted.

Qualifier 1: Media definition

generic-name

Specify the generic name of the media definitions to be deleted. A generic name is a character string that contains one or more characters followed by an asterisk (*). If a generic name is specified, then all media definitions that have names with the same prefix as the generic media definition name are deleted.

name

Specify the name of the media definition to be deleted.

Qualifier 2: Library

*LIBL

All libraries in the library list for the current thread are searched until the first match is found.

*CURLIB

The current library for the job is searched. If no current library entry exists in the library list, QGPL will be used to locate the media definitions to be deleted.

*USRLIBL

Only the libraries listed in the user portion of the library list are searched. If a specific media definition name is specified (instead of a generic name), only the first media definition found with that name is deleted.

*ALL

All libraries in the system, including QSYS, are searched.

*ALLUSR

All user libraries are searched. All libraries with names that do not begin with the letter Q are searched except for the following:

#CGULIB     #DSULIB     #SEULIB
#COBLIB     #RPGLIB
#DFULIB     #SDALIB

Although the following Qxxx libraries are provided by IBM, they typically contain user data that changes frequently. Therefore, these libraries are considered user libraries and are also searched:

QDSNX       QRCLxxxxx   QUSRIJS     QUSRVxRxMx
QGPL        QSRVAGT     QUSRINFSKR
QGPL38      QSYS2       QUSRNOTES
QMGTC       QSYS2xxxxx  QUSROND
QMGTC2      QS36F       QUSRPOSGS
QMPGDATA    QUSER38     QUSRPOSSA
QMQMDATA    QUSRADSM    QUSRPYMSVR
QMQMPROC    QUSRBRM     QUSRRDARS
QPFRDATA    QUSRDIRCL   QUSRSYS
QRCL        QUSRDIRDB   QUSRVI

1. 'xxxxx' is the number of a primary auxiliary storage pool (ASP).
2. A different library name, in the format QUSRVxRxMx, can be created by the user for each previous release supported by IBM to contain any user commands to be compiled in a CL program for the previous release. For the QUSRVxRxMx user library, VxRxMx is the version, release, and modification level of a previous release that IBM continues to support.

name

Specify the name of the library where the media definition is located.

Examples

DLTMEDDFN   MEDDFN(LIBA/MEDDFNA)

This command deletes the media definition named MEDDFNA in the library named LIBA from the system.
