swremove - unconfigure and remove software products
SYNOPSIS [Toc] [Back]
swremove [XToolkit Options] [-d|-r] [-i] [-p] [-v] [-C session_file]
[-f software_file] [-J jobid] [-Q date] [-S session_file]
[-t target_file] [-x option=value] [-X option_file]
[software_selections] [@ target_selections]
Remarks [Toc] [Back]
+ swremove supports an interactive user interface (GUI) that can
be invoked alone or by the sd command. See Interactive
Operation below.
+ This command supports operations on remote systems. See Remote
Operation below.
+ For an overview of all SD commands, see the sd(5) man page by
typing man 5 sd on the command line.
DESCRIPTION [Toc] [Back]
The swremove command removes software_selections from
target_selections (e.g. root file systems). When removing installed
software, swremove also unconfigures the software before it is
removed. The software is not unconfigured when removed from an
alternate root directory since it was not configured during
installation. When removing available software (within a depot),
swremove also does not perform the unconfiguration task.
NOTE : Selecting a bundle for removal does not always remove all
filesets in that bundle. If a particular fileset is required by
another bundle, that fileset will not be removed. For example, if the
bundles Pascal and FORTRAN both use the fileset Debugger.Run and you
try to remove FORTRAN, the fileset Debugger.Run will not be removed
because it is also used by the bundle Pascal. This prevents the
removal of one bundle from inadvertently causing the removal of
filesets needed by another bundle.
Remote Operation [Toc] [Back]
You can enable Software Distributor (SD) to manage software on remote
systems. To let the root user from a central SD controller (also
called the central management server or manager node) perform
operations on a remote target (also called the host or agent):
1) Install a special HP ServiceControl Manager fileset on the remote
systems. This enables remote operations by automatically setting
up the root, host, and template Access Control Lists (ACLs) on the
remote machines and permitting root access from the controller
system. To install the fileset, run the following command on each
remote system:
Hewlett-Packard Company - 1 - HP-UX 11i Version 2.0
swremove(1M) swremove(1M)
Hewlett-Packard Company
swinstall -s controller:/var/opt/mx/depot11 AgentConfig.SD-CONFIG
NOTES:
+ controller is the name of the central management server.
+ If the target is running HP-UX 10.20, use the same command but
substitute depot10 for depot11.
+ Targets previously set up by SD/OV to be managed by this
controller do not need this step.
+ SD does not require any other ServiceControl Manager filesets.
2) (Optional) Enable the GUI interfaces for remote operations by
creating the .sdkey file on the controller. Use this command:
touch /var/adm/sw/.sdkey
(This step is not required when you use SD from within the HP
ServiceControl Manager.)
NOTE: You can also set up remote access by using the swacl(1M) command
directly on the remote machines to grant root or non-root access to
users from the controller system.
Interactive Operation [Toc] [Back]
swremove supports a graphical user interface (GUI) or a terminal user
interface (in which screen navigation is done with the keyboard and no
mouse) if your terminal or display cannot support the GUI.
To invoke the GUI, type
swremove on the command line (without command-line arguments) or
include -i with any other command-line options when you invoke
swremove from the command line.
The sd command provides an interactive interface for monitoring
software jobs. You can also use it to invoke the swinstall, swcopy,
or swremove GUIs.
If you have enabled SD's central management features, swinstall,
swcopy, and swremove provide enhanced GUIs to support operations on
remote machines. See Remote Operations above.
Removing Patches or Patch Rollback Files [Toc] [Back]
To remove patch software, rollback files corresponding to the patch
must be available for rollback. You must remove the base software
modified by the patch. (Removing the base software also removes the
patches associated with that software.)

To commit (make permanent) a patch, use the swmodify command's
patch_commit option to remove the files saved for patch rollback, or
use the swinstall command's save_patch_files option to not save them
initially. See swmodify(1M) and swinstall(1M) for more information.
Control Scripts [Toc] [Back]
When removing installed software, the swremove command executes
several vendor-supplied scripts (if they exist) during the removal of
the software_selections. The swremove command supports the following
scripts:
checkremove
a script executed during the analysis of each
target_selection, it checks to make sure the removal can be
attempted. If this check fails, the software product will
not be removed.
preremove
a script executed immediately before the software files are
removed.
postremove
a script executed immediately after the software files are
removed.
unconfigure
a script executed during the unconfiguration of each
target_selection, it unconfigures the host for the software
(and the software for the host). The preremove and
postremove scripts are not intended for unconfiguration
tasks. They are to be used for simple file management needs
such as restoring files moved during install. The
unconfigure script allows the swremove command to
unconfigure the hosts on which it has been running before
removing the software specified.
Options [Toc] [Back]
The swremove supports the following options:
XToolKit Options
The swremove command supports a subset of the
standard X Toolkit options to control the
appearance of the GUI. The supported options are:
-bg, -background, -fg, -foreground, -display,
-name, -xrm, and -synchronous. See the X(1)
manual page for a definition of these options.
-d Operate on a depot rather than installed software.
-r Operates on an alternate root directory, which
must be specified the @ target_selections option.

swremove(1M) swremove(1M)
Hewlett-Packard Company
Note that unconfigure scripts are not run when
removing software from an alternate root
directory. (This option is not required for
alternate root operations but is maintained for
backward compatibility. See the Alternate Root
Directory and Depot Directory heading in sd(5) for
more information.)
-i Runs the command in interactive mode (Graphical
User Interface). See the Interactive Operation
and Remote Operation headings above for additional
details.
-p Previews a remove task by running the session
through the analysis phase only.
-v Turns on verbose output to stdout. (The swremove
log file is not affected by this option.) Verbose
output is controlled by the default verbose=x.
-C session_file
Save the current options and operands to
session_file. You can enter a relative or
absolute path with the file name. The default
directory for session files is
$HOME/.sw/sessions/. You can recall a session
file with the -S option.
-f software_file
Read the list of software_selections from
software_file instead of (or in addition to) the
command line.
-J jobid Executes a previously scheduled job. This is the
syntax used by the daemon to start the job.

swremove(1M) swremove(1M)
Hewlett-Packard Company
-Q date Schedules a job for the specified date. You can
change the date format by modifying the file
/var/adm/sw/getdate.templ.
-S session_file
Execute swremove based on the options and operands
saved from a previous session, as defined in
session_file. You can save session information to
a file with the -C option.
-t target_file Read the list of target_selections from
target_file instead of (or in addition to) the
command line.
-x option=value
Set the session option to value and override the
default value (or a value in an alternate
option_file specified with the -X option).
Multiple -x options can be specified.
-X option_file Read the session options and behaviors from
option_file.
Operands [Toc] [Back]
swremove supports two types of operands: software selections followed
by target selections. These operands are separated by the "@" (at)
character. This syntax implies that the command operates on "software
selections at targets".
Software Selections [Toc] [Back]
The selections operands consist of software_selections.
swremove supports the following syntax for each software_selection:
bundle[.product[.subproduct][.fileset]][,version]
product[.subproduct][.fileset][,version]
+ The = (equals) relational operator lets you specify
selections with the following shell wildcard and patternmatching
notations:
[ ], *, ?
For example, the following expression removes all bundles
and products with tags that end with "man":
swremove sw_server *man
+ Bundles and subproducts are recursive. Bundles can contain
other bundles and subproducts can contain other subproducts.
Hewlett-Packard Company - 5 - HP-UX 11i Version 2.0
swremove(1M) swremove(1M)
Hewlett-Packard Company
For example:
swremove bun1.bun2.prod.sub1.sub2.fset,r=1.0
or (using expressions):
swremove bun[12].bun?.prod.sub*,a=HP-UX
+ The \* software specification selects all products. Use this
specification with caution.
The version component has the form:
[,r <op> revision][,a <op> arch][,v <op> vendor]
[,c <op> category][,q=qualifier][,l=location]
[,fr <op> revision][,fa <op> arch]
+ location applies only to installed software and refers to
software installed to a location other than the default
product directory.
+ fr and fa apply only to filesets.
+ The <op> (relational operator) component can be of the form:
=, ==, >=, <=, <, >, or !=
which performs individual comparisons on dot-separated
fields.
For example, r>=B.10.00 chooses all revisions greater than
or equal to B.10.00. The system compares each dot-separated
field to find matches. Shell patterns are not allowed with
these operators.
+ The = (equals) relational operator lets you specify
selections with the shell wildcard and pattern-matching
notations:
[ ], *, ?, !
For example, the expression r=1[01].* returns any revision
in version 10 or version 11.
+ All version components are repeatable within a single
specification (e.g. r>=A.12, r<A.20). If multiple
components are used, the selection must match all
components.
+ Fully qualified software specs include the r=, a=, and v=
version components even if they contain empty strings.

swremove(1M) swremove(1M)
Hewlett-Packard Company
+ No space or tab characters are allowed in a software
selection.
+ The software instance_id can take the place of the version
component. It has the form:
[instance_id]
within the context of an exported catalog, where instance_id
is an integer that distinguishes versions of products and
bundles with the same tag.
Target Selections [Toc] [Back]
swremove supports the following syntax for each target_selection:
[host][:][/directory]
The : (colon) is required if both a host and directory are specified.
EXTERNAL INFLUENCES [Toc] [Back]
Default Options
In addition to the standard options, you can change swremove behavior
and policy options by editing the default values found in:
/var/adm/sw/defaults the system-wide default values.
$HOME/.swdefaults the user-specific default values.
Values must be specified in the defaults file using this syntax:
[command_name.]option=value
The optional command_name prefix denotes one of the SD commands. Using
the prefix limits the change in the default value to that command. If
you leave the prefix off, the change applies to all commands.
You can also override default values from the command line with the -x
or -X options:
command -x option=value
command -X option_file
The following section lists all of the keywords supported by swremove.
If a default value exists, it is listed after the "=".
The policy options that apply to swremove are:
admin_directory=/var/adm/sw (for normal mode)
admin_directory=/var/home/LOGNAME/sw (for nonprivileged mode)
The location for SD logfiles and the default parent

swremove(1M) swremove(1M)
Hewlett-Packard Company
directory for the installed software catalog. The
default value is /var/adm/sw for normal SD operations.
When SD operates in nonprivileged mode (that is, when
the run_as_superuser default option is set to true):
+ The default value is forced to /var/home/LOGNAME/sw.
+ The path element LOGNAME is replaced with the name
of the invoking user, which SD reads from the system
password file.
+ If you set the value of this option to HOME/path, SD
replaces HOME with the invoking user's home
directory (from the system password file) and
resolves path relative to that directory. For
example, HOME/my_admin resolves to the my_admin
directory in your home directory.
+ If you set the value of the
installed_software_catalog default option to a
relative path, that path is resolved relative to the
value of this option.
SD's nonprivileged mode is intended only for managing
applications that are specially designed and packaged.
This mode cannot be used to manage the HP-UX operating
system or patches to it. For a full explanation of
nonprivileged SD, see the Software Distributor
Administration Guide, available at the
http://docs.hp.com web site.
See also the installed_software_catalog and
run_as_superuser options.
agent_auto_exit=true
Causes the target agent to automatically exit after
Execute phase, or after a failed Analysis phase. This
is forced to false when the controller is using an
interactive user interface, or when -p (preview) is
used. This enhances network reliability and
performance. The default value of true causes the
target agent to automatically exit when appropriate.
When set to false, the target agent will not exit until
the controller ends the session.
agent_timeout_minutes=10000
Causes a target agent to exit if it has been inactive
for the specified time. This can be used to make
target agents more quickly detect lost network
connections since RPC can take as long as 130 minutes
to detect a lost connection. The recommended value is
Hewlett-Packard Company - 8 - HP-UX 11i Version 2.0
swremove(1M) swremove(1M)
Hewlett-Packard Company
the longest period of inactivity expected in your
environment. For command line invocation, a value
between 10 minutes and 60 minutes is suitable. A value
of 60 minutes or more is recommended when the GUI will
be used. The default of 10000 is slightly less than 7
days.
allow_split_patches=false
Permits the use of single patch filesets without
"sibling" filesets. In the default state of false,
removal of a single fileset from a multi-fileset patch
automatically includes any other fileset that are part
of the patch, based on the ancestor filesets of the
target fileset. (This behavior applies to filesets
selected directly by the user and to filesets
automatically selected by SD to resolve software
dependencies.)
When set to true, SD allows a single patch fileset to
be removed without including the sibling filesets. This
allows a target to contain a patch that has been
"split" into its component filesets. WARNING:
Splitting a patch can create a situation in which one
fileset in a sibling group would be removed by a patch,
while the other filesets would not.
auto_kernel_build=true
Normally set to true. Specifies whether the removal of
a kernel fileset should rebuild the kernel or not. If
the kernel rebuild succeeds, the system automatically
reboots. If set to false, the system continues to run
the current kernel.
If the auto_kernel_build option is set to true, the
autoreboot option must also be set to true. If the
auto_kernel_build option is set to false, the value of
the autoreboot option does not matter.
autoreboot=false
Prevents the removal of software requiring a reboot
from the non-interactive interface. If set to true,
then this software can be removed and the target
system(s) will be automatically rebooted.
An interactive session always asks for confirmation
before software requiring a reboot is removed.
If the auto_kernel_build option is set to true, the
autoreboot option must also be set to true. If the
auto_kernel_build option is set to false, the value of
the autoreboot option does not matter.

swremove(1M) swremove(1M)
Hewlett-Packard Company
autoremove_job=false
Controls automatic job removal. If the job is
automatically removed, job information (job status or
controller/agent log files) cannot be queried with
swjob.
autoselect_dependents=false
Automatically selects all software that depends on the
specified software. When set to true, and any software
that other software depends on is selected for removal,
swremove automatically selects that other software. If
set to false, automatic selections are not made to
resolve requisites.
autoselect_reference_bundles=true
If true, bundles that have the is_sticky attribute set
to true will be automatically removed when the last of
its contents is removed. If false, the sticky bundles
will not be automatically removed.
compress_index=false
Determines whether SD commands create compressed INDEX
and INFO catalog files when writing to target depots or
roots. The default of false does not create compressed
files. When set to true, SD creates compressed and
uncompressed INDEX and INFO files. The compressed files
are named INDEX.gz and INFO.gz, and reside in the same
directories as the uncompressed files.
Compressed files can enhance performance on slower
networks, although they may increase disk space usage
due to a larger Installed Products Database and depot
catalog. SD controllers and target agents for HP-UX
11.01 and higher automatically load the compressed
INDEX and INFO files from the source agent when:
+ The source agent supports this feature.
+ INDEX.gz or INFO.gz exist on the source depot.
+ INDEX.gz or INFO.gz are not older than the
corresponding uncompressed INDEX or INFO files.
The uncompressed INDEX or INFO file is accessed by the
source agent if any problem occurs when accessing,
transferring, or uncompressing the INDEX.gz or INFO.gz
file.
controller_source=
Specifies the location of a depot for the controller to
access to resolve selections. Setting this option can
Hewlett-Packard Company - 10 - HP-UX 11i Version 2.0
swremove(1M) swremove(1M)
Hewlett-Packard Company
reduce network traffic between the controller and the
target. Use the target selection syntax to specify the
location:
[host][:][path]
This option has no effect on which sources the target
uses and is ignored when used with the Interactive User
Interface.
distribution_target_directory=/var/spool/sw
Defines the default location of the target depot.
enforce_dependencies=true
Requires that all dependencies specified by the
software_selections be resolved at the
target_selections. For swremove, if a selected fileset
has dependents (i.e. other software depends on the
fileset) and they are not selected, do not remove the
selected filesets. If set to false, dependencies will
still be checked, but not enforced.
enforce_scripts=true
Controls the handling of errors generated by scripts.
If true, and a script returns an error, the swremove
operation halts. An error message appears reporting
that the execution phase failed. If false, all script
errors are treated as warnings, and swremove attempts
to continue operation. A warning message appears
reporting that the execution succeeded. The message
wording identifies whether the failure occurred in the
configure/unconfigure, checkremove, preremove, or
postremove phases.
force_single_target=false
This option applies only to the Interactive User
Interface when no SD-OV license is in effect on a
system that is a diskless server. It causes swremove to
run in a single target mode, even though a diskless
server normally causes swremove to run in multi-target
mode.
installed_software_catalog=products
Defines the directory path where the Installed Products
Database (IPD) is stored. This information describes
installed software. When set to an absolute path, this
option defines the location of the IPD. When this
option contains a relative path, the SD controller
appends the value to the value specified by the
admin_directory option to determine the path to the
IPD. For alternate roots, this path is resolved
Hewlett-Packard Company - 11 - HP-UX 11i Version 2.0
swremove(1M) swremove(1M)
Hewlett-Packard Company
relative to the location of the alternate root. This
option does not affect where software is installed,
only the IPD location.
This option permits the simultaneous installation and
removal of multiple software applications by multiple
users or multiple processes, with each application or
group of applications using a different IPD.
Caution: use a specific installed_software_catalog to
manage a specific application. SD does not support
multiple descriptions of the same application in
multiple IPDs.
See also the admin_directory and run_as_superuser
options, which control SD's nonprivileged mode. (This
mode is intended only for managing applications that
are specially designed and packaged. This mode cannot
be used to manage the HP-UX operating system or patches
to it. For a full explanation of nonprivileged SD, see
the Software Distributor Administration Guide,
available at the http://docs.hp.com web site.)
job_title=
Specifies an ASCII string giving a title to a job. It
is displayed along with the job ID to provide
additional identifying information about a job when
swjob is invoked.
log_msgid=0
Adds numeric identification numbers at the beginning of
SD logfile messages:
0 (default) No identifiers are attached to messages.
1 Adds identifiers to ERROR messages only.
2 Adds identifiers to ERROR and WARNING messages.
3 Adds identifiers to ERROR, WARNING, and NOTE
messages.
4 Adds identifiers to ERROR, WARNING, NOTE, and
certain other informational messages.
logdetail=false
Controls the amount of detail written to the log file.
When set to true, this option adds detailed task
information (such as options specified, progress
statements, and additional summary information) to the
log file. This information is in addition to log
information controlled by the loglevel option.
See the loglevel option and the sd(5) manual page for
more information.
Hewlett-Packard Company - 12 - HP-UX 11i Version 2.0
swremove(1M) swremove(1M)
Hewlett-Packard Company
logfile=/var/adm/sw/swremove.log
This is the default command log file for the swremove
command.
loglevel=1
Controls the log level for the events logged to the
command logfile, the target agent logfile, and the
source agent logfile. This information is in addition
to the detail controlled by the logdetail option.
0 provides no information to the logfile.
1 enables verbose logging to the log files.
2 enables very verbose logging to the log files.
See the logdetail option and the sd(5) manual page for
more information.
mount_all_filesystems=true
By default, the swremove command attempts to
automatically mount all filesystems in the /etc/fstab
file at the beginning of the analysis phase, to ensure
that all listed filesystems are mounted before
proceeding. This policy helps to ensure that files
which may be on mounted filesystems are available to be
removed.
If set to false, the mount operation is not attempted,
and no check of the current mounts is performed.
polling_interval=2
Defines the polling interval used by the Interactive UI
of the controller. It specifies how often each target
agent will be polled to obtain status information about
the task being performed. When operating across widearea
networks, the polling interval can be increased to
reduce network overhead.
remove_empty_depot=true
Controls whether a depot is removed once the last
product/bundle has been removed. Useful to set to
false if you want to retain existing depot ACLs for
subsequent depot reuse.
rpc_binding_info=ncacn_ip_tcp:[2121] ncadg_ip_udp:[2121]
Defines the protocol sequence(s) and endpoint(s) on
which the daemon listens and the other commands contact
the daemon. If the connection fails for one protocol
sequence, the next is attempted. SD supports both the
tcp (ncacn_ip_tcp:[2121]) and udp (ncadg_ip_udp:[2121])
protocol sequence on most platforms.
Hewlett-Packard Company - 13 - HP-UX 11i Version 2.0
swremove(1M) swremove(1M)
Hewlett-Packard Company
See the sd(5) manual page (type man 5 sd) for more
information.
rpc_timeout=5
Relative length of the communications timeout. This is
a value in the range from 0 to 9 and is interpreted by
the DCE RPC. Higher values mean longer times; you may
need a higher value for a slow or busy network. Lower
values give faster recognition on attempts to contact
hosts that are not up or not running swagentd. Each
value is approximately twice as long as the preceding
value. A value of 5 is about 30 seconds for the
ncadg_ip_udp protocol sequence. This option may not
have any noticeable impact when using the ncacn_ip_tcp
protocol sequence.
run_as_superuser=true
This option controls SD's nonprivileged mode. This
option is ignored (treated as true) when the invoking
user is super-user.
When set to the default value of true, SD operations
are performed normally, with permissions for operations
either granted to a local super-user or set by SD ACLs.
(See swacl(1M) for details on ACLs.)
When set to false and the invoking user is local and is
not super-user, nonprivileged mode is invoked:
+ Permissions for operations are based on the user's
file system permissions.
+ SD ACLs are ignored.
+ Files created by SD have the uid and gid of the
invoking user, and the mode of created files is set
according to the invoking user's umask.
SD's nonprivileged mode is intended only for managing
applications that are specially designed and packaged.
This mode cannot be used to manage the HP-UX operating
system or patches to it. For a full explanation of
nonprivileged SD, see the Software Distributor
Administration Guide, available at the
http://docs.hp.com web site.
See also the admin_directory and
installed_software_catalog options.
software= Defines the default software_selections. There is no
supplied default. If there is more than one software
Hewlett-Packard Company - 14 - HP-UX 11i Version 2.0
swremove(1M) swremove(1M)
Hewlett-Packard Company
selection, they must be separated by spaces.
software_view=products
Indicates the software view to be used by the
Interactive UI of the controller. It can be set to
products, all_bundles, or a bundle category tag to
indicate to show only bundles of that category.
targets= Defines the default target_selections. There is no
supplied default (see select_local above). If there is
more than one target selection, they must be separated
by spaces.
target_shared_root=
This option applies to HP-UX 10.X only.
Defines the default location of the alternate root
directory.
verbose=1 Controls the verbosity of the output (stdout). A value
of
0 disables output to stdout. (Error and warning
messages are always written to stderr).
1 enables verbose messaging to stdout.
write_remote_files=false
Prevents the removal of files from a remote (NFS) file
system. When set to false, files on a remote file
system are not removed.
If set to true and if the superuser has write
permission on the remote file system, the remote files
are removed.
Session File [Toc] [Back]
Each invocation of swremove defines a task session. The command
automatically saves options, source information, software selections,
and target selections before the task actually commences. This lets
you re-execute the command even if the session ends before the task is
complete. You can also save session information from interactive or
command-line sessions.
Session information is saved to the file
$HOME/.sw/sessions/swremove.last. This file is overwritten by each
invocation of the command. The file uses the same syntax as the
defaults files.
From an interactive session, you can save session information into a
file at any time by selecting the Save Session or Save Session As
option from the File menu.
Hewlett-Packard Company - 15 - HP-UX 11i Version 2.0
swremove(1M) swremove(1M)
Hewlett-Packard Company
From a command-line session, you can save session information by
executing the command with the -C session__file option. You can
specify an absolute path for a session file. If you do not specify a
directory, the default location is $HOME/.sw/sessions/.
To re-execute a saved session from an interactive session, use the
Recall Session option from the File menu.
To re-execute a session from a command-line, specify the session file
as the argument for the -S option.
When you re-execute a session file, the values in the session file
take precedence over values in the system defaults file. Likewise,
any command-line options and parameters take precedence over the
values in the session file.
Software and Target Lists [Toc] [Back]
The swremove command supports software and target selection from
separate input files.
You can specify software and target selection lists with the -f and -t
options. Software and targets specified in these files are selected
for operation instead of (or in addition to) files listed in the
command line. (See the -f and -t options for more information.)
Additionally, the swremove interactive user interface reads a default
list of hosts on which to operate. The list is stored in:
/var/adm/sw/defaults.hosts the system-wide default
list of hosts
$HOME/.swdefaults.hosts the user-specific default
list of hosts
For each interactive command, target hosts containing roots or depots
are specified in separate lists (hosts and hosts_with_depots
respectively.) The list of hosts are enclosed in { } braces and
separated by white space (blank, tab and newline). For example:
swremove.hosts={hostA hostB hostC hostD hostE hostF}
swremove.hosts_with_depots={hostS}
Environment Variables [Toc] [Back]
The environment variable that affects the swremove command is:
LANG Determines the language in which messages are
displayed. If LANG is not specified or is set to the
empty string, a default value of C is used. See the
lang(5) man page by typing man 5 sd for more
information.

configuration variable script, /etc/rc.config.d/LANG.
For example, /etc/rc.config.d/LANG, must be set to
LANG=ja_JP.SJIS or LANG=ja_JP.eucJP to make the agent
and daemon log messages display in Japanese.
LC_ALL Determines the locale to be used to override any values
for locale categories specified by the settings of LANG
or any environment variables beginning with LC_.
LC_CTYPE Determines the interpretation of sequences of bytes of
text data as characters (e.g., single-versus multibyte
characters in values for vendor-defined attributes).
LC_MESSAGES [Toc] [Back]
Determines the language in which messages should be
written.
LC_TIME Determines the format of dates (create_date and
mod_date) when displayed by swlist. Used by all
utilities when displaying dates and times in stdout,
stderr, and logging.
TZ Determines the time zone for use when displaying dates
and times.
Environment variables that affect scripts are:
SW_CATALOG [Toc] [Back]
Holds the path to the Installed Products Database
(IPD), relative to the path in the SW_ROOT_DIRECTORY
environment variable. Note that you can specify a path
for the IPD using the installed_software_catalog
default option.
SW_CONTROL_DIRECTORY [Toc] [Back]
Defines the current directory of the script being
executed, either a temporary catalog directory, or a
directory within in the Installed Products Database
(IPD). This variable tells scripts where other control
scripts for the software are located (e.g. subscripts).
SW_CONTROL_TAG [Toc] [Back]
Holds the tag name of the control_file being executed.
When packaging software, you can define a physical name
and path for a control file in a depot. This lets you
define the control_file with a name other than its tag
and lets you use multiple control file definitions to
point to the same file. A control_file can query the
SW_CONTROL_TAG variable to determine which tag is being

executed.
SW_LOCATION [Toc] [Back]
Defines the location of the product, which may have
been changed from the default product directory. When
combined with the SW_ROOT_DIRECTORY, this variable
tells scripts where the product files are located.
SW_PATH A PATH variable which defines a minimum set of commands
available for use in a control script (e.g.
/sbin:/usr/bin).
SW_ROOT_DIRECTORY [Toc] [Back]
Defines the root directory in which the session is
operating, either "/" or an alternate root directory.
This variable tells control scripts the root directory
in which the products are installed. A script must use
this directory as a prefix to SW_LOCATION to locate the
product's installed files. The configure script is
only run when SW_ROOT_DIRECTORY is /.
SW_SESSION_OPTIONS [Toc] [Back]
Contains the pathname of a file containing the value of
every option for a particular command, including
software and target selections. This lets scripts
retrieve any command options and values other than the
ones provided explicitly by other environment
variables. For example, when the file pointed to by
SW_SESSIONS_OPTIONS is made available to a request
script, the targets option contains a list of
software_collection_specs for all targets specified for
the command. When the file pointed to by
SW_SESSIONS_OPTIONS is made available to other scripts,
the targets option contains the single
software_collection_spec for the targets on which the
script is being executed.
SW_SOFTWARE_SPEC [Toc] [Back]
This variable contains the fully qualified software
specification of the current product or fileset. The
software specification allows the product or fileset to
be uniquely identified.
Additional environment variables that affect scripts for swremove are:
PRE_UNIX95 [Toc] [Back]
This variable and the UNIX95 variable are exported with
a value that forces "classic" behavior of swremove
instead of UNIX95 behavior. For HP-UX 10.30 and later
versions, this variable is set to "1".

SW_SESSION_IS_KERNEL [Toc] [Back]
Indicates whether a kernel build is scheduled for the
current install/remove session. A TRUE value indicates
that the selected kernel fileset is scheduled for a
kernel build and that changes to /stand/system are
required. A null value indicates that a kernel build
is not scheduled and that changes to /stand/system are
not required.
The value of this variable is always equal to the value
of SW_SESSION_IS_REBOOT.
SW_SESSION_IS_REBOOT [Toc] [Back]
Indicates whether a reboot is scheduled for a fileset
selected for removal. Because all HP-UX kernel
filesets are also reboot filesets, the value of this
variables is always equal to the value of
SW_SESSION_IS_KERNEL.
UNIX95 This variable, along with the PRE_U95 variable, is
exported with a value that forces "classic" behavior of
swremove instead of UNIX95 behavior. For the 10.30 or
later release of HP-UX, this variable is cleared.
Signals [Toc] [Back]
The swremove command catches the signals SIGQUIT, SIGINT, and SIGUSR1.
If these signals are received, the command prints a message, sends a
Remote Procedure Call (RPC) to the agents to wrap up after completion,
and then exits.
The agent ignores SIGHUP, SIGINT, and SIGQUIT. It immediately exits
gracefully after receiving SIGTERM, SIGUSR1, or SIGUSR2. Killing the
agent may leave corrupt software on the system, and thus should only
be done if absolutely necessary. Note that when an SD command is
killed, the agent does not terminate until completing the task in
progress.
The daemon ignores SIGHUP, SIGINT and SIGQUIT. It immediately exits
gracefully after receiving SIGTERM and SIGUSR2. After receiving
SIGUSR1, it waits for completion of a copy or remove from a depot
session before exiting, so that it can register or unregister depots
if necessary. Requests to start new sessions are refused during this
wait.
Each agent will complete the removal task (if the execution phase has
already started) before it wraps up. This avoids leaving software in
a corrupt state.
