The Print Big Object tool assists in determining the large size
objects on your system. This can help cleanup of a system. One or
more libraries may be processed by a single command. An optional
exception file may be used to avoid flagging those objects which are
known to be large.
The advantage of the exception file is that you can specify objects
that are known to be large so you can minimize the number of listed
objects you need to review.
IFS objects are not included. Use the TAA DSPIFS command to list the
large IFS objects.
A typical command would be:
PRTBIGOBJ LIB(*ALLUSR) SIZE(10000000)
All objects in user libraries would be checked and those which are
equal to or exceed 10,000,000 bytes would be listed in the spooled
An optional exception file may be used to specify those objects which
are known to exceed the size you specify.
To create the exception file, enter:
Two files (BIGOBJP and BIGOBJL) will be created in QGPL.
After you run PRTBIGOBJ to determine the large objects, enter:
Enter the library, object, object type and optionally an exception
size for those objects that you do not want to flag. If no exception
size is entered, the size is considered to be *NOMAX and the object
will never be flagged.
If you have a large object, but want to enter a size to check against
instead of the value of the SIZE parameter on PRTBIGOBJ, you can flag
the object if it grows beyond the size you enter. For example,
assume an object is 20,000,000 bytes today. If you enter 25,000,000
as a size, the object will be flagged if it exceeds 25,000,000. If
the object does not exceed 25,000,000 bytes, the listing will
optionally include the object, but the flag will not exist.
PRTBIGOBJ escape messages you can monitor for
None. Escape messages from based on functions will be re-sent.
CRTBIGOBJ Command parameters *CMD
SRCLIB The source library to use for the QATTDDS file
source. The default is *TAAARC. If a full license
exists, the source is used from the TAA Archive. If
a demonstration license exists, the source is used
from the QATTDDS file in the TAATOOL library.
A specific user library may be named, but the source
file must be QATTDDS.
AUT The authorization to the BIGOBJP file in QGPL. The
default is *USE. *CHANGE or *EXCLUDE may be
DLTBIGOBJ Command parameters *CMD
WRKBIGOBJ Command parameters *CMD
PRTBIGOBJ Command parameters *CMD
LIB The list of libraries to be processed. Up to 300
libraries may be entered (including generic names)
or the special values *LIBL, *USRLIBL, *CURLIB,
*ALLUSR, *ALLUSR2, *ALLNONQ, *IBM, or *ALL.
For *LIBL and *USRLIBL, if a current library exists,
it will be considered before the libraries on the
user portion of the library list. If the current
library is also part of the user portion of the
library list, it will only appear once.
*ALLUSR means any library that was not created by
the system according to the CHKIBMLIB command.
*ALLUSR2 means any library that meets the criteria
specified for the SAVLIB LIB(*ALLUSR) function.
This excludes # libraries such as #SEULIB and
includes QUSRSYS, QGPL, etc. See the help text for
the SAVLIB LIB parameter for a complete description.
*ALLNONQ means any library that does not begin with
the letter Q.
An entry of *IBM causes all libraries to be included
as per the definition of the CHKIBMLIB tool.
Product libraries (those in the product portion of
the library list) are never included.
You must have *ALLOBJ special authority to use a
value of *ALL, *ALLUSR, *ALLUSR2, *ALLNONQ, or *IBM.
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
*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
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
Element 2: Search type
*ASP = Specifies that only the single auxiliary
storage pool (ASP) device named in element 1 is to
*ASPGRP = Specifies that the entire group of the
primary auxiliary storage pool (ASP) device named in
element 1 is to be searched.
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)
SIZE The size of an object to be flagged if it is equal
to or greater than the values entered. The default
is 5,000,000 bytes.
Note that if an exception file exists, the object
may be listed and flagged. See the ALLBIG
ALLBIG A *YES/*NO option for whether to print all the big
objects regardless of whether there is an exception
record in the BIGOBJP file.
*YES is the default which will print all objects,
but only flag those that exceed the SIZE value or
the size entered into the exception file.
*NO may be specified to list only those objects that
1) Exceed the SIZE value and are not described in
the BIGOBJP file or 2) Are described in the BIGOBJP
file and exceed the exception size entered.
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.
You must have *ALLOBJ special authority to use a library value of
*ALL, *ALLUSR, *ALLUSR2, *ALLNONQ, or *IBM.
