Understanding the HP Serviceguard Extension for Oracle E-Business Suite (SGeEBS)

6. /etc/cmcluster/scripts/ebs/apps (Module scripts of APPS Tier)

tkit_module.sh - APPS Tier Module script

tkit_gen.sh - APPS Tier Configuration file generator script

SGeEBS is fully modularized and it is not required to modify the configuration files haebsdb.conf and

ebsapps.conf for setting up SGeEBS in a cluster.

SGeEBS configuration

Follow the instructions in the chapter “Building an HA Cluster Configuration” in the manual

“Managing HP Serviceguard” to create the logical volume infrastructure on shared disks. The disk

must be available to all clustered nodes that will be configured to run SGeEBS. Create file systems on

all logical volumes on the volume groups.

SGeEBS can be configured in two different modes. The first mode is install directory operation in

which the scripts remain in the installation directory. The second mode is the configuration directory

operation. In this mode, the user can copy the scripts from the installation directory (including contents

of subdirectories) to the configuration directory and define this location in the parameter “TKIT_DIR” in

the package configuration file.

For example, the directory ebs is copied from the install directory /opt/cmcluster/ebs to the

configuration directory /etc/cmcluster/mypackage/.

Now the “TKIT_DIR” will be /etc/cmcluster/mypackage/ebs/,

APPS specific scripts will be in $TKIT_DIR/apps/ (/etc/cmcluster/mypackage/ebs/apps/), DB

specific scripts will be in $TKIT_DIR/db/ (/etc/cmcluster/mypackage/ebs/db)

Serviceguard first tries to use the toolkit.sh script in the configuration directory. If this script is not

found in the configuration directory, it takes them from the installation directory.

The example configuration uses installation directory mode operation. This example on SGeEBS

Package Setup and Configuration is for an EBS installation using LVM. There should be separate

Volume groups for DB Tier and APPS Tier.

In this example, the volume groups and mount points are assumed to be configured as follows:

For DB Tier

Volume Groups Mount point

-----------

vg_OracleDBBinaries /oradb/ora home

vg_OracleDBData /oradb/data

For APPS Tier

Volume Groups Mount point

-----------

vg_OracleAppsTier /oraapps
