Enterprise Cluster Master Toolkit User Guide April 2011 (5900-1606)

will be predefined, include the identity of the database instance as per the name set in the /etc/
cmcluster/modules/ecmt/db2/ directory.
For legacy packages, there will be one user configuration script (hadb2.conf) and three
functional scripts (toolkit.sh), hadb2.sh and hadb2.mon) which work with each other to
integrate DB2 with the Serviceguard package control scripts.
For modular packages, there is an Attribute Definition File (ADF), a Toolkit Module Script
(tkit_module.sh), and a Toolkit Configuration File Generator Script (tkit_gen.sh) which
work with the three scripts mentioned above for legacy packages to integrate DB2 with the
Serviceguard Master Control Script.
Table 9 (page 76) lists these scripts:
Table 9 Legacy Package Scripts
DescriptionScript Name
This script contains a list of pre-defined variables that the user must customize
for use with a particular database instance. This is a configuration file which
is read by the toolkit script, hadb2.sh. The table Table 10 (page 76) shows
variables that are contained in hadb2.conf.
hadb2.conf (user configuration file)
This script contains a list of internally used variables and functions that support
starting and stopping of a DB2 database instance. This script will be called
by toolkit.sh to perform the following:
• On package startup, it starts the DB2 instance and monitor process.
• On package halt, it stops the DB2 instance and monitor process.
Main Script (hadb2.sh)
This script contains a list of internally used variables and functions for
monitoring a DB2 server instance. This script will be called by hadb2.sh . It
uses a tool called "db2gcf" to monitor the database.
Monitor Script (hadb2.mon)
This script is the interface between the Serviceguard package control script
and the DB2 toolkit.
Interface Script (toolkit.sh)
