Decompress Object (DCPOBJ)

The Decompress Object (DCPOBJ) command allows you to permanently decompress programs, panel groups, menus, display files, printer files, modules, and service programs.

Compressed objects use less storage space than decompressed objects. When a compressed object is used or a compressed program is called, a decompressed version of the object automatically becomes available to the user.
Decompressed objects use the system storage space allocated to them and are in a final, ready-to-use state.
Temporarily Decompressed Objects are temporarily decompressed copies of compressed objects. The system allocates storage space for the temporary copies until the system or the user determines that the temporary storage space needs to be reclaimed.
Temporary storage is automatically reclaimed when:
- The RCLTMPSTG command is run
- The next initial program load (IPL) is run
- The object is used often enough to cause the system to permanently decompress it
When an object is permanently decompressed, the compressed version of the object is destroyed as well as any temporary forms of the object; however, compressed versions remain intact as long as the objects are temporarily decompressed.

Restriction: The user must have *USE authority to the objects specified on the command and execute authority to the library containing the objects.

Object (OBJ)

Specifies the name and library of the object to be decompressed.

This is a required parameter.

The possible values are:

*ALL: All objects in the specified library of the object type specified on the Object type prompt (OBJTYPE parameter) are decompressed.
generic*-object-name: Specify the generic name of the object to be decompressed. A generic name is a character string that contains one or more characters followed by an asterisk (*).
object-name: Specify the name of the object to be decompressed.

The possible library values are:

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

*USRLIBL: If a current library entry exists in the library list for the current thread, the current library and the libraries in the user portion of the library list are searched. If there is no current library entry, only the libraries in the user portion of the library list are searched.

*CURLIB: Only the current library is searched. If no current library entry exists in the library list, QGPL is used.

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

'xxxxx' is the number of a primary auxiliary storage pool (ASP).
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.

library-name: Specify the name of the library to be searched.

Object type (OBJTYPE)

Specifies the type of object to be decompressed. You can specify *ALL, or you can specify one or more of the other possible values.

This is a required parameter.

The possible values are:

*ALL: All compressed menus, panel groups, display and printer device files, programs, modules, and service programs with the name and library specified on the Object prompt (OBJ parameter) are decompressed.
*FILE: Display and printer device files with the name and library specified on the Object prompt (OBJ parameter) are decompressed.
*MENU: Menus with the name and library specified on the Object prompt (OBJ parameter) are decompressed.
*MODULE: Modules with the name and library specified on the Object prompt (OBJ parameter) are decompressed.
*PGM: Programs with the name and library specified on the Object prompt (OBJ parameter) are decompressed.
*PNLGRP: Panel groups with the name and library specified on the Object prompt (OBJ parameter) are decompressed.
*SRVPGM: Service programs with the name and library specified on the Object prompt (OBJ parameter) are decompressed.
