Configuring Packages and Their Services
Choosing Package Modules
Chapter 6 297
The variable name and value can each consist of a maximum of
MAXPATHLEN characters (1024 on HP-UX systems).
You can define more than one variable. See “About External Scripts” on
page 178, as well as the comments in the configuration file, for more
information.
external_pre_script The full pathname of an external script to be
executed before volume groups and disk groups are activated during
package startup, and after they have been deactivated during package
shutdown (that is, effectively the first step in package startup and last
step in package shutdown). New for modular packages.
If more than one external_pre_script is specified, the scripts will be
executed on package startup in the order they are entered into this file,
and in the reverse order during package shutdown.
See “About External Scripts” on page 178, and the comments in the
configuration file, for more information and examples.
external_script The full pathname of an external script. This script is
often the means of launching and halting the application that constitutes
the main function of the package. New for modular packages.
The script is executed on package startup after volume groups and file
systems are activated and IP addresses are assigned, but before services
are started; and during package shutdown after services are halted but
before IP addresses are removed and volume groups and file systems
deactivated.
If more than one external_script is specified, the scripts will be
executed on package startup in the order they are entered into this file,
and in the reverse order during package shutdown.
See “About External Scripts” on page 178, and the comments in the
configuration file, for more information and examples.
user_name Specifies the name of a user who has permission to
administer this package. See also user_host and user_role; these three
parameters together define the Access Control Policy for this package
(see “Access Roles” on page 204). These parameters must be defined in
this order: user_name, user_host, user_role.
