Converting from a standalone system to a single system image

If you want to convert from an existing Blueworx Voice Response or DirectTalk system to a single system image, you should consider the following:

• The data from only one Blueworx Voice Response or DirectTalk system can be restored into a single system image using the restoreDT command. This is because most of the database is shared, and would therefore get overwritten if you attempted to restore on another node in the single system image.
• If you have multiple systems that have identical application objects (for example, state tables and voice segments) and voice data, you can use the saveDT command on any of the systems to save a copy of your data. You can use the DTlsapobj and DTlsvmobj commands (see the description of these commands in the Blueworx Voice Response for AIX: Managing and Monitoring the System information) to display information about application and voice objects to confirm that all the objects are on all of the existing systems.
• If you have multiple systems that have different application objects, you need to plan very carefully before you convert to an SSI environment. You must check what application objects exist on each system, and resolve any conflicts. You can use the DTlsapobj and DTlsvmobj commands to list the application and voice objects on each system.

  When you know which objects you want, export them all to one Blueworx Voice Response or DirectTalk system and run the saveDT command on that system.

When you have saved a copy of the data that you want, use the restoreDT utility to restore it to the database server node you set up in the single system image.

Typically you will want to create a single system image starting from one of the following points:

You have new Power Systems

If you have new hardware that you want to configure as a single system image, you must perform the following steps:

1. Create a new Blueworx Voice Response user ID on every system, using the AIX smit or mkuser command. The user ID must be defined identically on every system. This task is described in Setting up the AIX account (single system image only).
2. Install Blueworx Voice Response on every system. This task is described in Starting installation of Blueworx Voice Response.
3. Configure one of the systems as a server node and the others as client nodes. This task is described in the Blueworx Voice Response for AIX: Configuring the System information.

You have existing stand-alone systems

1. Save your existing data.
2. Uninstall Blueworx Voice Response or DirectTalk from each system.
3. Create an additional user ID on each system (this user ID must be identical on every system).
   Note: If you do not want to create new user IDs, you can change the existing user ID on each system to make them all identical.
4. Install Blueworx Voice Response on every system.
5. Use vae.setuser to ensure the file systems and ownerships are correct.
6. Configure every system as an SSI node.
7. Restore your data on to the database server node of your single system image.
