 The PRTLIBANL  command is  intended to  be used to  determine how  many
 objects  exist in  a  library or  in  a total  system.   It  produces a
 report  with the  library name,  number of objects  and size.   It also
 totals  the   number  of  programs,   the  number   of  data   physical
 files/records,  the  number  of   source  files/members/records  and  a
 breakdown  by source type.   At the  end of the report  it analyzes all
 the objects by type  and size and then  makes special summaries of  the
 types  of programs,  types  of files  and  types of  source.   It  also
 provides summaries from a Save/Restore viewpoint and by owner.

 The  command should  be submitted  to batch.   PRTLIBANL  requires some
 long running commands  to build files  and an RPG program  to read  the
 files.   If the command is  to be executed  for the entire  system (all
 libraries), it  should be submitted  by the Security  Officer to ensure
 that all objects can be read.

 If  the entire  system is  analyzed, the  size of  the total  number of
 objects will  not agree to  the information which  is displayed by  the
 WRKSYSSTS  command.     Only   external  objects  are   accumulated  by
 PRTLIBANL.    Therefore,  the auxiliary  storage  requirements  for the
 licensed internal  code,  directories  and temporary  objects  are  not
 included.   The amount excluded will  vary.  See the  later discussion.

 If a  single library is analyzed,  the name of the  library is used for
 the spooled  print  file.   If  multiple libraries  are  analyzed,  the
 output is to the PRTLIBANL file.

 Command parameters                                    *CMD

    LIB           Enter the name  of the library, generic library,  or a
                  list  of up  to  300 libraries  to be  analyzed.   The
                  special  values *ALL, *USRLIBL,  *ALLUSR, *ALLNONQ, or
                  *TEST may  be entered  (see the  TSTLIB parameter  for
                  *TEST).  Also see the OMITLIB parameter.

                  If  *ALL is  specified, additional  processing occurs.

    LIBTYPE       Whether  to select  all or  a specified  library type.
                  *ALL is the default to select all types.

                  *PROD may  be used  to select  only production  (PROD)

                  *TEST  may  be   used  to  select  only   test  (TEST)

    ASP           Whether  to process  all or  just  the libraries  in a
                  specific ASP.  The  default is *ALL for  all ASPs.   A
                  specific ASP may be named in a range of 1-99.

    LIBONLY       A *YES/*NO  value that  defaults to  *NO.  *YES  means
                  that only  the first part of the  report (one line per
                  library)  will  be  printed.   The  other  analysis is
                  suppressed.   This does  not significantly impact  the
                  time it takes to perform PRTLIBANL.

                  For  a better  performing  one line  summary, use  the
                  PRTLIBCNT  TAA Tool.   This provides only  a count and
                  size by library.

    OMITLIB       A list  of  up to  300  libraries or  generic  library
                  names that should  be omitted.  *NONE  is the default.

                  An omit list may not be entered for LIB(*CURLIB).

                  Any library entered is checked for existence.

                  No check  occurs to see if an  omit library would have
                  been  selected.    For   example,  if  LIB(*LIBL)   is
                  entered with  OMITLIB(ABC) and library  ABC is  not on
                  the library list, no error occurs.

    TSTLIB        Running   a   test   of   *ALL   libraries   takes   a
                  considerable  amount of  time.  To  allow for testing,
                  a test library may  be named to contain the  files and
                  data  for  TAALIBAP,  TAALIBAP2  and  TAALIBAQ.    For
                  normal use, the default should be used.

                  TAALIBAP  must  contain DSPFD  *MBR  data.   TAALIBAP2
                  must contain  DSPOBJD  data.   TAALIBAQ  must  contain
                  DSPOBJD data for library objects in QSYS.

    DLYHRS        The number of  hours to delay execution.   The default
                  is 0  meaning to execute immediately.   If a number is
                  specified, the  command  will delay  after  it  begins

                  If  LIB(*ALL)  is specified,  the  command  should  be
                  submitted  to  batch.    If  submitted to  batch,  the
                  DLYJOB  parameter  would causes  the  job to  begin to
                  execute and then be delayed by the DLYJOB command.

                  The  intent of  this  parameter  is to  allow  you  to
                  submit  the command  before  going home  at night  and
                  allow  the command to execute  after your normal batch
                  work is done.

    PRTFILE       The qualified name  of the printer file  to use.   The
                  default is TAAPRT1  in *LIBL.  If a  single library is
                  analyzed,  the name  of the spooled  file will  be the
                  library name.   If  multiple libraries  are  analyzed,
                  PRTLIBANL will be the name of the printer file.

 System Size Summary

 If  LIB(*ALL) is  requested,  information is  presented  to attempt  to
 reconcile  the storage amount  used described  on WRKSYSSTS  versus the
 storage  that can be  accounted for in  libraries.  The  method used by
 PRTLIBANL is  not  exact, but  can provide  a  better understanding  of
 storage usage.

 The  Operational  Assistant  (OA)  provides  a  similar  function  that
 accesses  internal information  and has  accurate information.   Use GO
 ASSIST, then option  11 and then option  4 for Disk  Space Tasks.   The
 output from PRTLIBANL may be more desirable.

 The system reports  storage in millions of  bytes, megabytes, kilobytes
 and  bytes.  To avoid  confusion, all the information  is translated to
 millions of bytes and rounded.

 The first output includes  one line per library  and summarizes all  of
 the  objects found  in  libraries.    System libraries  account  for  a
 significant amount of space.

 An  ASP summary  is then shown  which prints  one line  per ASP.   This
 information  comes from a combination  of the WRKDSKSTS information and
 by counting objects/sizes by ASP.

 The WRKDSKSTS  information  includes the  amount  of storage  for  each
 disk unit  and the percentage used.   This is summarized by  ASP and an
 overall  percentage is shown of  usage by ASP.   If checksums are used,
 the amount  of total  storage by  ASP does  not  include the  temporary
 space  nor the  amount  of checksum  space.    Consequently, the  total
 amount of storage will not match the disk configuration.

 The  amount of storage used  is summarized from WRKSYSSTS  as the total
 amount to account for.   If there  is only a single  ASP (only ASP  1),
 the total  from WRKDSKSTS  and WRKSYSSTS  are the same  for both  total
 storage and usage.

 When PRTLIBANL  is run, it will not account  for storage found in QTEMP
 libraries  that are active  at the time.   These will  be accounted for
 in  the user  profile  storage  summary,  but not  in  the  summary  of
 objects  found in  libraries.   For the  best results,  you  should run
 PRTLIBANL when  no other jobs are active and  when a new job is started
 (e.g.  SBMJOB) for PRTLIBANL.

 Not all objects  on the  system are  kept in libraries.   However,  the
 user profile keeps  a reasonably accurate account of  the storage owned
 per profile.   If you suspect the  user profile numbers are inaccurate,
 causing an abnormal  IPL will cause  authorization recovery which  will
 verify the  numbers.   The  numbers can  be  used to  account for  some
 space  that is outside  of libraries.   DSPUSRPRF  is used to  create a
 data base file of all profiles and the storage owned is summarized.

 For  certain  system supplied  profiles, it  is  normal to  own objects
 that are not in  libraries.  Examples of this ownership  include office
 distribution items  owned by QDOC,  data base formats owned  by QDBSHR,
 and  internal   operating  system  objects  owned  by  QSYS.    Several
 profiles are  printed in  detail  as well  as a  single total  for  all
 other profiles.

 The  total owned  that is  in libraries  is subtracted  from the  total
 kept in  the user profiles.   The difference in all  of the profiles is
 added.   In some  cases a  profile may  own more  storage in  libraries
 than is found in the  user profile storage value.  This  is normally an
 indication of  1) other jobs  are active when  PRTLIBANL is run  or 2),
 the  user profile storage value  is off.  If  the user profile value is
 less than the library value, the difference is ignored.

 The size  of the licensed  internal code  is added.   The size  differs
 from 9402/9404 versus 9406.

 To allow  for a dump of main  memory, a reserved space  exists which is
 created to be the same size.  This amount is added.

 On  each disk (other  than the  load source unit),  a 1  million + byte
 area  is  used  for  cross   referencing  purposes.    This  value   is
 multiplied  by the  number of  disk units  found on  WRKDSKSTS and  the
 amount is added.

 When PRTLIBANL  runs, the TAA tools CVTDSKSTS  and CVTSYSSTS are run to
 gather the  information  about  storage  used.    Following  this,  the
 outfiles are  created in  QTEMP for  DSPOBJD and DSPFD  for the  entire
 system.   While  QTEMP becomes  quite large  during the  PRTLIBANL job,
 the  size  is  not  considered  because  of  when  the  information  is
 captured  by CVTDSKSTS,  CVTSYSSTS  and  when the  user  profile  owned
 storage is retrieved.

 The  licensed  internal code  uses  a  variety  of tables  and  control
 blocks  that cannot be accounted  for by PRTLIBANL.   The major factors
 are the size of the Error  log, Trace tables and VLOG.  Default  values
 are shipped which can  be changed using SST.  For the  VLOG, the system
 varies  the default based on  the size of  the system.   An estimate is
 used for these internal  values (based on the  size of the system)  and
 the estimate is added.

 It  is   possible  that   your  system   may  have   been  changed   to
 significantly  alter the  size of some  of these  areas.   For example,
 the  trace table can  be set to a  very large value.   To determine the
 actual values of  the major factors, use  STRSST.  The following  shows
 the  SST menu  structure and  the options  to take.   Although  you are
 primarily  taking 'Change'  options, no changes  will occur  if use F12
 when the actual 'Change Displays' are  shown.  Note that for the  Error
 Log, the system defaults  are for a small system  and the display shows
 recommended  sizes.   If  you  have sufficient  auxiliary  storage, you
 should consider changing the sizes to the recommended values.

 When a system  is IPLed, the  system creates space for  a given  number
 of jobs.   This  storage will  hold the  PAGs and other  space used  by
 active jobs.   The number of job areas  created is controlled by system
 values.   If  the amount of  jobs active at  a given  time exceeds this
 number, additional  structures are  created.   Only an  IPL will  reset
 the  structures to their  original value.   This  space is  spread over
 the available disk units.

 The  internal storage management directory  which contains the location
 of every object  and the allocations  assigned on disk  is also  spread
 over the  available disk  units.   Other internal  objects also  spread
 over available disk units.

 The  size of  this internal space  (PAGs, storage  management directory
 etc.) can  be  estimated by  beginning  with the  'Current  Unprotected
 Used' amount  shown on WRKSYSSTS.   This value  is intended to  be used
 in planning  for Checksums.  The  total shown includes the  size of the
 load   source  unit  which  is  never   checksummed  so  it  should  be
 subtracted.  The  load source unit  is always the  first unit shown  on
 WRKDSKSTS.  The  remaining value is the amount  of internal space usage
 on  all the disk  units except  the load source  unit.   There are also
 internal spaces on the load source  unit.  The size is approximated  by
 dividing the  remainder by  the number  of disk  units (minus the  load
 source)  and then adding the  average to the remainder.   This estimate
 is then added.

 All the additive amounts are summed  and added to the total of  objects
 found in libraries.   A comparison is then made to  the WRKDSKSTS value
 and  a difference printed.   Because of  the technique used,  the final
 difference can be plus or minus.

 when LIB(*ALL) is specified.
