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 QPRINT 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 QPRINT in *LIBL. If a single library is
analyzed, the name of the spooled file will be the
library name. If all libraries are analyzed, QPRINT
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
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
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.
See the prior comments about the accuracy of the total storage found
when LIB(*ALL) is specified.
