The Display Empty Libraries command displays or lists one or more
libraries that have no objects. The command performs quickly as the
simplest form of the API to retrieve object information is used.
You must have *ALLOBJ special authority to use DSPEMTLIB.
A typical command would be:
DSPEMTLIB LIB(*ALLUSR)
A display would appear with one line per library that did not have
any objects. Only user libraries would be checked (same definition
as used for SAVLIB LIB(*ALLUSR).
DSPEMTLIB escape messages you can monitor for
---------------------------------------------
None. Escape messages from based on functions will be re-sent.
DSPEMTLIB Command parameters *CMD
----------------------------
LIB The library or libraries to be checked. A generic
name may be used. The special values *ALL or
*ALLUSR may also be used.
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.
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: Device
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
*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.
OUTPUT How to output the results. * is the default to
display the spooled file if the command is entered
interactively. If the display is ended with F3/F12
or the Enter key, the spooled file is deleted after
it is displayed. To retain the spooled file, you
may use the the System Request 'Cancel' function and
the spooled file will exist in a HLD status.
If the command is entered in batch or *PRINT is
specified, the spooled file is output and retained.
