6.5.1 Setting up the service group sample

Before using the Service group sample, it must be deployed on your grid

instance. As ibmgrid, issue the following command:

igt-deploy-gar /opt/IBMGrid/gars/ServiceGroupCounterService.gar

Because the Service group sample was created to interact with unsecure

services, you must disable security for this service. Follow these steps:

1. Open the file in Example 6-8 in your preferred editor.

Example 6-8 Service group sample security file

/opt/IBMGrid/AppServer/installedApps/DefaultNode/IBMGrid.ear/ogsa.war/schema

/security/servicegroup/ServiceGroupRegistrationDefaultSecurity-Server.xml

2. Search the configuration file for the text shown in Example 6-9.

Example 6-9 Original security setting

<securityConfig xmlns="http://www.globus.org">

<auth-method>

<pkey/>

<gsi/>

</auth-method>

</securityConfig>

3. Replace the text in Step 2 with the text in Example 6-10.

Example 6-10 New security setting

<securityConfig xmlns="http://www.globus.org">

<auth-method>

<none/>

</auth-method>

</securityConfig>

4. Save the changes to the configuration file.

After deployment and when security has been disabled, restart the container

using the igt-stop-container and igt-start-container commands.

Important: This service group sample only runs with security disabled.
