The Display  Job Description Libraries  command provides  two functions
for one,  generic, or all job descriptions: 1)  A simple listing of the
libraries  in  each job  description 2)  A  check for  any non-existent
libraries.  The output is either displayed or listed.

You must  have *ALLOBJ  special authority  to use  a qualified  library
name of *ALL or *ALLUSR.

To list all libraries in all job descriptions, specify:

             DSPJOBDLIB  JOBD(*ALL/*ALL)

To check all job descriptions for non-existent libraries, specify:


The DLTJOBDLIB  command may  be used  to delete a  library from  one or
more job descriptions.

System handling of libraries in Job Descriptions

A  job always requires  that a  Job Description (*JOBD)  object type be
assigned.  A Job Description may  be used to assign the libraries  used
in  the library  list  for  the job  and  in  some cases  is  required.
Therefore,  a question  arises that is  'What does  the system do  if a
library in a JOBD no longer exists?'

When SBMJOB  is  used,  the  INLLIBL  parameter  defaults  to  *CURRENT
meaning the  current library  list is used  in batch.   If  *CURRENT is
used,  it  does not  matter  what  libraries are  defined  for the  Job
Description  specified  in the  JOBD parameter  for  SBMJOB.   Only the
current list is used.

Assume that you  created Job Description ABC  with an INLLIBL of  LIB1,
LIB2, and LIB3.   What would happen if LIB3 were  deleted and no longer
existed?   If you specify  SBMJOB and take the  default for INLLIBL the
system never bothers to check if LIB3 exists.

However, if you specified:

             SBMJOB  CMD(xxx) JOBD(ABC) INLLIBL(*JOBD)

the SBMJOB command will fail because LIB3 does not exist.

When an  interactive job  is started,  it also  uses a  JOBD and  would
fail if a library did not exist.

There are  other ways of  submitting a batch  job besides  SBMJOB (such
as  a Job  Scheduling Job).   These types  of jobs generally  have more
considerations about whether a library exists.

Because most  batch  jobs  are  submitted by  using  the  defaults  for
SBMJOB, there  is a  good possibility  that several JOBDs  on a  system
will contains  libraries that no longer exist.   You can use DSPJOBDLIB
to help determine where these exist to assist in cleanup.

DSPJOBDLIB escape messages you can monitor for

None.  Escape messages from based on functions will be re-sent.

DSPJOBDLIB Command parameters                         *CMD

   JOBD          The   qualified  name  of  the  job  description.    A
                 generic name or *ALL may be entered.

                 The library  value  defaults  to *LIBL.    A  specific
                 library,  *USRLIBL, *CURLIB, *ALLUSR,  or *ALL  may be

   CHECK         A  *YES/*NO   option  for  whether  to  check  if  the
                 libraries specified in  the job  description exist  on
                 the system or just list the libraries.

                 *NO is  the default to  simply list all  the libraries
                 that are specified in the job descriptions.

                 *YES   may  be   specified  to  check   the  libraries
                 specified in  the  job  descriptions to  see  if  they
                 still exist.

   OUTPUT        How  to output  the  results.   *  is the  default  to
                 display  the spooled  file if  the command  is entered
                 interactively.   The spooled file  is deleted after it
                 is displayed.

                 If  the command  is  entered  in batch  or  *PRINT  is
                 specified, the  spooled file  is output  and retained.


You  must have  *ALLOBJ special  authority to  use a  qualified library
name of *ALL or *ALLUSR.
