Enabling Multisite Updates Using the Control Center

As of Version 6, you can use the Control Center to provide multisite update. The procedure is very simple, and is outlined below. For more information about the multisite update con®guration process, including how to con®gure your system manually, refer to the on-line Connectivity Supplement.

Starting the Multisite Update Smartguide

From the Control Center, click on the [+] sign to expand the tree view. With the right mouse button, select the instance that you wish to con®gure. A popup menu opens. Select Multisite Update->Con®gurefrom this menu.

Smartguide Steps

The Smartguide provides a notebook-type interface. Each page of the notebook will prompt you for certain information about your con®guration. The pages are shown below in the order in which you will encounter them.

Step 1. Specify a Transaction Processor (TP) monitor.

This ®eld will show the defaults for the TP Monitor you have enabled. If you do not wish to use a TP monitor, select Do Not Use a TP Monitor.

Step 2. Specify the communications protocols you will use.

Step 3. Specify a Transaction Manager database.

This panel defaults to the ®rst database you connect to (1ST_CONN).

You can leave this default or select another catalogued database.

Step 4. Specify the types of database servers involved in the update, and also whether or not TCP/IP is to be used exclusively.

Step 5. Specify the Syncpoint Manager settings.

This page will only appear if the settings on the previous page indicate that you need to use DB2's Syncpoint Manager in a multisite update scenario.

Testing the Multisite Update Feature
