Configuring Packages and Their Services
Editing the Configuration File
Chapter 6 223
• If your package uses a large number of volume groups or disk groups,
or mounts a large number of file systems, consider increasing the
values of the following parameters:
— concurrent_fsck_operations—specifies the number of parallel
fsck operations that will be allowed at package startup (not used
for Red Hat GFS).
— concurrent_mount_and_umount_operations—specifies the
number of parallel mount operations allowed during package
startup and unmount operations during package shutdown.
•Use the fs_ parameters (see page 213) to specify the characteristics
of file systems and how and where to mount them. See the comments
in the FILESYSTEMS section of the configuration file for more
information and examples.
• Specify the filesystem mount and unmount retry options. For Red
Hat GFS (see fs_type on page 213), use the default (zero).
• You can use the pev_ parameter to specify a variable to be passed to
external scripts. Make sure the variable name begins with the
upper-case or lower-case letters pev and an underscore (_). You can
specify more than one variable. See “About External Scripts” on
page 122, and the comments in the configuration file, for more
information.
• If the package will run an external script, use the external_script
parameter to specify the full pathname of the script, for example
$SGCONF/pkg1/script1.
See “About External Scripts” on page 122, and the comments in the
configuration file, for more information.
• If you want the package to run an external “pre-script” during
startup and shutdown, use the external_pre_script parameter to
specify the full pathname of the script, for example
$SGCONF/pkg1/pre_script1.
See “About External Scripts” on page 122, and the comments in the
configuration file, for more information.
• Configure the Access Control Policy for up to eight specific users or
any_user.
