Modular package support in Serviceguard for Linux Toolkits, August 2008

Modifying the package

Modifying the parameters of a package can be done in two ways: after halting the package or

after putting the package in maintenance mode.

After halting the package

If the user is using Serviceguard for Linux 11.18 or earlier, he/she needs to halt the package

before its configuration can be modified. After the package configuration has been modified and

applied, the user might want to induce various modifications such as modifying the package

configuration by either reconfiguring the already existing parameters or by adding additional

modules to the package configuration file. The modified package configuration then needs to be

re-applied.

The sequence of operations for modifying the package is:

1) #cmmakepkg –i pkg_old.conf –m <module> pkg_new.conf

This command adds a module, if required, to the already existing package configuration file

pkg_old.conf and creates a new package configuration file pkg_new.conf. The module added

can be any supported module such as a Serviceguard for Linux module or another toolkit module.

Reconfigure the package configuration file appropriately.

If the toolkit configuration file is updated after the package configuration file is created, then the

package configuration file has to be updated by giving the following command.

#cmmakepkg –i pkg_old.conf –m <module> –t toolkit.conf pkg_new.conf

In addition to adding the package parameters, this command extracts the toolkit parameters from

the toolkit.conf file and updates the pkg_new.conf file. Modify the values of existing attributes of

the package conf file, if required.

Note:

In the case of Oracle, Samba and PostgreSQL toolkits, the toolkit configuration file has parameters

that are in turn being used by other parameters in the same file. It is the responsibility of the user

to ensure that the changes done to these parameters are reflected across the toolkit configuration

file.

2) #cmapplyconf –P pkg_new.conf

New package configuration is applied. This completes the migration of legacy toolkit to modular

toolkit.

After putting the package in Maintenance mode

This is the mode supported by the existing toolkit scripts. Kindly refer to the toolkit README file for

more information on this mode.
