HP Enterprise Cluster Master Toolkit User Guide (5900-2131, December 2011)

• Create the Serviceguard package using Modular method.
Follow these steps to create Serviceguard package using Modular method:
1. Create a directory for the package:
#mkdir /etc/cmcluster/pkg/db2_pkg/
2. Copy the toolkit template and script files from db2 directory:
#cd /etc/cmcluster/pkg/db2_pkg/
#cp /opt/cmcluster/toolkit/db2/* ./
3. Create a configuration file (pkg.conf) as follows:
#cmmakepkg -m ecmt/db2/db2 pkg.conf
4. Edit the package configuration file.
NOTE: DB2 toolkit configuration parameters in the package configuration file have
been prefixed by ecmt/db2/db2 when used in Serviceguard A.11.19.00 or later. For
example,
/etc/cmcluster/pkg/db2_pkg/pkg.conf
The configuration file should be edited as indicated by the comments in that file. The
package name needs to be unique within the cluster. For clarity, use the name of the
database instance to name the package. For example,
PACKAGE_NAME db2_payroll
List the names of the clustered nodes to be configured to run the package, using the
NODE_NAME parameter.
NODE_NAME node1
NODE_NAME node2
Set the script_log_file variable. For example,
script_log_file /etc/cmcluster/pkg/<pkg_dir>/log
Set the TKIT_DIR variable as the path of <package_directory>. For example,
TKIT_DIR /etc/cmcluster/pkg/db2_pkg
Set the INSTANCE_NAME variable as the DB2 instance name. For example,
INSTANCE_NAME db2_payroll_inst
Set the PARTITION_NUMBER variable to the partition numbers of the database which
need to be started, stopped and monitored using this package. By default it is set to 0.
Repeat the above variable to add additional partitions. For example,
PARTITION_NUMBER 0
PARTITION_NUMBER 1
NOTE: Logical partitions of a database can be grouped to run in a single package
while physical partitions need separate packages for each.
Set the MONITOR_PROCESSES variable to process names, which must be monitored and
cleaned up to ensure fail safe shutdown of the DB2 Instance or Partition. The actual
monitoring is done by a command called db2gcf. The MONITOR_PROCESSES is only
used to kill the processes that remain alive after the shutdown of the database. By default,
.db2sysc. is configured in this variable. Repeat the variable to additional processes if
required. For example,
MONITOR_PROCESSES db2sysc
Set the MAINTENANCE_FLAG variable to “yes” or “no”, to “enable” or “disable” the
maintenance mode feature for the package. For example,
