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 (for
example, single versus multibyte characters in values for vendor-defined attributes).
LC_MESSAGES
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.
Signals
The
swpackage command catches the signals SIGQUIT and SIGINT. If these signals are received, the
command prints a message, sends a Remote Procedure Call (RPC) to the agents to wrap up, 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.
Locking
SD commands use a common locking mechanism for reading and modifying both root directories and
software depots. This mechanism allows multiple readers but only one writer on a root or depot.
The SD commands which modify software in an (alternate) root directory are restricted from simultane-
ous modification using
fcntl() locking on the file
var/adm/sw/products/swlock
relative to the root directory (for example, /var/adm/sw/products/swlock
).
The SD commands which modify software in a depot are restricted from simultaneous modification using
fcntl() locking on the file
catalog/swlock
relative to the depot directory (for example, /var/spool/sw/catalog/swlock
).
All commands set
fcntl() read locks on roots and depots using the swlock file mentioned above.
When a read lock is set, it prevents other SD commands from performing modifications (that is, from set-
ting write locks).
PRODUCT SPECIFICATION FILE
This section summarizes the product_specification_file (PSF) which drives the
swpackage session. See
swpackage (4) for a detailed description of PSF syntax and semantics.
A PSF is structured as follows:
[depot specification ]
[vendor specification ]
[category specification ]
[bundle specification ]
[product specification ]
[control script specification ]
[subproduct specification ]
[fileset specification ]
[control script specification ]
[file specification ]
