Serviceguard Toolkit Internal File Structure
HP provides a set of scripts for the framework proposed for ASM integration with Serviceguard.
The ECMT Oracle scripts contain the instance specific logic to start/stop/monitor both the ASM
and the database instance. These scripts support both legacy and the modular method of packaging.
Even though, Legacy method of packaging is supported, it is deprecated now and will not be
supported in future. Hence, it is recommended to use modular style of packaging. For more
information on creating a modular package, look at the Serviceguard manual Managing
ServiceGuard manual available at http://www.hp.com/go/hpux-serviceguard-docs —>HP
Serviceguard latest edition at http://www.hp.com/go/hpux-serviceguard-docs -> HP Serviceguard.
Serviceguard provides tools to migrate existing legacy packages to modular packages. For more
information, look at the whitepaper “Migrating Packages from Legacy to Modular Style” available
at http://www.hp.com/go/hpux-serviceguard-docs -> HP Serviceguard.
Legacy packages use the package configuration file and the package control script for the ASM
or database instance on the Serviceguard specific side. The package configuration file parameters
are stored in the Serviceguard configuration database (CDB) at cmapplyconf time, and are used
by the package manager in its actions on behalf of this package. The control script invokes the
ASM or the database instance specific functions for start/stop/monitor through the toolkit interface
script (toolkit.sh). On the instance specific side, there is a toolkit configuration file (haoracle.conf)
which is sourced by the start/stop/monitor (haoracle.sh,haoracle_sql.sh,
haoracle.mon, and halistener.mon) script files. The toolkit interface script allows the
start/stop/monitor calls to remain unaffected by changes in the instance specific scripts. Figure 5,
shows the internal file structure for legacy packages.
