Adding a CDD File to the Project

The configuration settings for an application are defined in the CDD file. You can use the wizard to specify the default cluster and object management(OM) mode of your project.

If you choose an OM type in the wizard, the template for that OM type is used and all the default settings are loaded. For example, if you choose Cache, then a cache agent with default values is created for you. For example, if you change from Cache to Store and save, the cache agent and its configuration are lost. For all OM types, however, the General settings are configured in the same way. Similarly, you can choose the Cluster Provider Type to get a template for the cluster of your choice.

Procedure
1. In TIBCO BusinessEvents Studio Explorer, right-click the folder where you want to store the CDD and select New > Cluster Deployment Descriptor. The New Cluster Configuration Wizard opens up.
2. In the File name field, type a name for the CDD and click Next. You can change the name in the editor as required.
   Note:  When you are using TIBCO Administrator for deployment, by default, TIBCO Administrator looks for a processing unit named default and a CDD file named default.

3. In the Object Manager Selection page, select a cluster type for the project.

   • Unclustered
   • Clustered

   Based the cluster type, the values of the Object Management Type field are listed.

4. Select the Object Management Type for the deployment and click Finish.

   The available options are described in the following table:

   Cluster Type	Object Management Type
   Unclustered	In Memory Sets In Memory as the Object Management Mode (in CDD). Store Sets Store as the Object Management Mode. The default Store Provider is Apache Cassandra; however, you can change it later in CDD, if required
   Clustered	Cache Sets Legacy ActiveSpaces as the Cluster Provider and Cache as the Object Management Mode. The default cache provider is Legacy ActiveSpaces. Store Sets TIBCO FTL as the Cluster Provider and Store as the Object Management Mode. The default store provider is Apache Cassandra; however, you can change it, if required.

   The CDD editor opens up.

   Tip: Check the Object Management node on the left and ensure that you have selected the correct Object Management type.

   You can also right-click the Object Management element and select Change to OM Type.

5. In the CDD editor, on the Cluster tab, select General and specify the following:

   The cluster name, although it already contains the file name that you have provided in the new CDD wizard, but you can update it, if needed. If Legacy ActiveSpaces is the cluster provider, any spaces in the name are converted to underscore characters internally.

   Note: Do not use the names $cluster or default as they are reserved names.

   If required, you can update the author name and add comments as suitable. (Version and date are not editable.)
6. Save the new CDD file.
