The Display Object Description 4 command is a problem determination
aid and is similar to DSPOBJD2. DSPOBJD4 allows any object
description on the system to be displayed if the user has *USE
authority to the TAADSPOBJ4 authorization list. 'Display only'
functions for additional object level information are also provided
for most object types. No data can be displayed.
If the user has *CHANGE authority to TAADSPOBJ4, the DSPOBJAUT
function may also be used from the detail display.
The F8 function key on the detail display allows more detail
information about the object such as its description. Certain object
types are excluded such as DSPUSRPRF, WRKJRNA, and DSPJRNRCVA.
A typical command is entered as:
DSPOBJD2 OBJ(PGMA) OBJTYPE(*PGM)
If multiple PGMA *PGM objects exist on the library list, a subfile is
displayed. Multiple libraries are displayed on a single display.
F11 may be used to flip/flop between displaying the object text
descriptions and the storage sizes. Each object shown may be
selected for the detail display including the library object.
If only a single PGMA is found on the library list, the detail
display is presented immediately.
The detail display combines the important information provided by
DSPOBJD for both the *FULL and *SERVICE options of the DETAIL
parameter. This allows a good review of the important information
about an object including the source member/file/library used for the
create.
TAADSPOBJ4 Authorization List
-----------------------------
The user must have at least *USE authority to the TAADSPOBJ4
Authorization List to make any use of DSPOBJD4.
If *CHANGE authority exists, the F9 key for DSPOBJAUT is usable to
display all the authorizations to the object.
Differences with DSPOBJD2
-------------------------
DSPOBJD2 is the same function with the following differences:
** DSPOBJD4 requires the user be authorized to the TAADSPOBJ4
*AUTL.
** DSPOBJD2 only allows access to objects the user is authorized
to. DSPOBJD4 adopts the security officer profile thus
allowing access to all objects.
** DSPOBJD2 allows the user to use DSPOBJAUT for any object he
has authority to, but the system function prevents seeing all
authorizations unless the user is the owner. DSPOBJD4
provides a full DSPOBJAUT display, but only if the user has
*CHANGE authority to the TAADSPOBJ4 *AUTL.
** Some F8 functions differ or are constrained such as:
-- DSPUSRPRF is not valid on DSPOBJD4.
-- DSPDTAARAD is used instead of DSPDTAARA which displays
both the description and the data.
-- DSPUSRSPCA is not valid because it allows an option to
display the data.
-- For data base file objects, DSPFD is used instead of
DSPF2 which allows a display of the data.
-- WRKJRNA and DSPJRNRCVA are not valid on DSPOBJD4
because they allow 'work type' of options.
DSPOBJD4 escape messages you can monitor for
--------------------------------------------
TAA9895 No objects exist for the selection criteria
Escape messages from based on functions will be re-sent.
DSPOBJD4 Command parameters *CMD
---------------------------
OBJ The qualified object name to be displayed. The
object name can be generic or the special value
*ALL.
*ALLUSR or *IBM may also be entered if the object
type is *LIB.
The library value defaults to *LIBL. The other
special values that may be entered are *CURLIB,
*ALL, or *ALLUSR.
OBJTYPE The object type to be displayed. The default is
*ALL for all object types. All of the values
supported by DSPOBJD are provided.
OBJATTR The object attribute to be displayed. The default
is *ALL. An attribute such as RPG, or PF may be
entered to subset the object type being requested.
If you enter a value, you should also use the
OBJTYPE parameter to improve the performance.
A generic value may be entered such as RPG* which
would include all generic values such as RPG, RPG38,
and RPGLE programs.
ASPDEV Specifies the auxiliary storage pool (ASP) device
name where storage for the library containing the
object is allocated. If the library resides in an
ASP that is not part of the thread's library name
space, this parameter must be specified to ensure
the correct library is searched. If this parameter
is used when the library qualifier specified for the
Object prompt (OBJ parameter) is *CURLIB, *LIBL, or
*USRLIBL, ASPDEV(*) is the only valid value.
This parameter can be specified as a list of two
values (elements) or as a single value. The
possible single values are:
* = The ASPs that are currently part of the thread's
library name space will be searched to locate the
library. This includes the system ASP (ASP 1), all
defined basic user ASPs (ASPs 2-32), and, if the
thread has an ASP group, the primary and secondary
ASPs in the thread's ASP group.
*ALLAVL = All available ASPs will be searched. This
includes the system ASP (ASP 1), all defined basic
user ASPs (ASPs 2-32), and all available primary and
secondary ASPs, (ASPs 33-255) with a status of
'Available'.
*CURASPGRP = If the thread has an ASP group, the
primary and secondary ASPs in the thread's ASP group
will be searched to locate the library. The system
ASP (ASP 1) and defined basic user ASPs (ASPs 2-32)
will not be searched. If no ASP group is associated
with the thread, an error will be issued.
*SYSBAS = The system ASP (ASP 1) and all defined
basic user ASPs (ASPs 2-32) will be searched to
locate the library. No primary or secondary ASPs
will be searched even if the thread has an ASP
group.
Element 1:
ASP Device name. The device name of the primary or
secondary ASP to be searched. The primary or
secondary ASP must have been activated (by varying
on the ASP device) and have a status of 'Available'.
The system ASP (ASP 1) and defined user basic ASPs
(ASPs 2-32) will not be searched.
Element 2: Search type. Specifies that only the
*ASP = Specifies that only the single auxiliary
storage pool (ASP) device named in element 1 is to
be searched.
*ASPGRP = Specifies that the entire group of the
primary auxiliary storage pool (ASP) device named in
element 1 is to be searched.
ESCAPE Whether to send an escape message if no objects
exist for the selection criteria. The default is
*YES which means the TAA9895 escape message would be
sent.
*NO may be specified in which case the user would
see an empty subfile with an appropriate message.
