    2. To start the database manager instance, select the instance, click with the right mouse button and select the Start option from the pop-up menu.

Modifying an instance's communications settings may require you to update the database connection catalogs on the client. You do this as follows: Using the command line processor on the client, uncatalog and recatalog the communication node and/or database information, depending on the values changed on the server. For more information on cataloging using the command line processor, see Chapter 14. Configuring Client-to-Server Communications Using the Command Line Processor. Using the Client Configuration Assistant on the client, select the database connection you want to change and then clicm on the Properties button. This will launch a Smartguide that will help you wiht the changes. For more information on cataloging using the Client Configuration Assistant, see Chapter 13.
