Editing Cluster Deployment Descriptor (CDD) File

You define the cluster member machines, processing units, and agents in the Cluster Deployment Descriptor (CDD) which is an XML file. The CDD file is configured in the CDD editor in Studio.

You can edit any CDD file in the following ways:

•	Using text editor

•	Using Studio

Editing CDD File using Text Editor

The CDD file is a XML file, you can use any text or XML editor to edit the file. To edit any property in the CDD file, locate the property and set the new value in the value field.

To edit the CDD file, do following:

1.	Open the CDD file in a text editor.

2.	Set the value of the property, as needed. For example, to edit the value of discover URL for a cluster, you can set the property as follows:

   <property name="be.engine.cluster.as.discover.url"    value="tcp://Machine1_IPAddress:port1;Machine2_IPAddress:port1;

        Machine3_IPAddress:port1/"/>

3.	Save the changes to the file.

Editing CDD File using Studio

You can edit a CDD file using the Studio as follows:

1.	Navigate to the ASG_HOME/bin directory.

2.	Copy the CDD file (for example, asg_core.cdd) file to ASG_HOME/projects/ASG_DefaultImplementation folder.

3.	Navigate to the ASG_HOME/studio/eclipse directory.

4.	Type the following command to start the Studio:

Windows platform

studio.exe

UNIX platform

./studio

5.	If you are prompted, select or create the Eclipse workspace directory where your project files will be stored. (If you check the option to use this workspace as a default, you are not prompted again.)

6.

Click OK.

7.	Close the Welcome screen.

8.	From the File menu select Import.

9.	In the Import Select wizard, select an import source as General > Existing Projects into Workspace and click Next. You see the Import Projects dialog.

10.	In the Import Projects dialog Select root directory field, browse to and select the project: ASG_HOME/projects/ASG_DefaultImplementation.

11.	Click Finish.

12.	In the Studio Explorer, expand the ASG_DefaultImplementation project node. Verify that you see the CDD file (for example, asg_core.cdd) file.

13.	Double-click the CDD file (for example asg_core.cdd) file.

14.	Select the appropriate tab to edit the properties. For example, see Set Discover URL, Set Max Active, Set Priority.

15.	Save the changes to the file.

16.	Back up the original CDD file (for example, asg_core.cdd) file in the ASG_HOME/bin directory.

17.	Copy the modified CDD file (for example asg_core.cdd) file from ASG_HOME/projects/ASG_DefaultImplementation to the ASG_HOME/bin directory.

If you select the "Copy projects into workspace" option during the import of the project, then the modified asg_core.cdd file exists in the workspace directory. Make sure to copy the asg_core.cdd file from workspace directory to the ASG_HOME/bin directory.

Task C Set Discover URL

a.	To set the discover URL for a cluster, select Cluster tab > Properties on the left. On the right, expand cluster node to edit the following properties:

      be.engine.cluster.as.discover.url

b.	Set the values to the actual IP address of the machine, and an unused port.

For example,

   be.engine.cluster.as.discover.url=tcp://Machine1_IPAddress:port1;Machi       ne2_IPAddress:port1;Machine3_IPAddress:port1;Machine4_IPAddress:port1/

c.	Save the changes to the resource.

Task D Set Max Active

This task explains the steps to setup the Max Active property for an agent.

a.	Select Agent Classes tab.

b.	Select an agent node for which you want to set the Max Active property.

For example, to set the Max Active property for Global Throttle Manager engine, select the gtm-class(Inference) node.

c.	On the right side, click the following property to set a value as follows:

      Max Active 1

d.	Save the changes to the resource.

Task E Set Priority
