Setting Up TCP/IP Support

---

By default, TCP/IP is supported between Pervasive.SQL clients and remote engines. If you have modified the default settings or need to verify that TCP/IP support is available, refer to this section.

Note
In order to perform any of the tasks in this section, you must have administrative rights on the NetWare server, or be a member of the Pervasive_Admin group defined on the server.

   Enabling TCP/IP Support

Follow this procedure to ensure that the database engine can communicate with clients over TCP/IP networks.

1. From the Start menu, choose Programs4Pervasive.SQL V84Control Center.
2. In the PCC window, double-click on Pervasive.SQL Engines to display a list of the engines registered with PCC.

   If the engine you want to configure is not listed, right-click on Pervasive.SQL Engines and choose Register New Engine.

3. Double-click on the icon representing your target engine. Double-click Configuration. Login if prompted. Double-click Server. Click on Communication Protocols. In the window to the right, double-click on Supported Protocols.
4. A smaller dialog box appears, showing a list of Available protocols and a list of Selected protocols. If the list of Selected protocols includes the value Microsoft TCP/IP, then TCP/IP is already supported.

   If the list of Selected protocols does not include Microsoft TCP/IP, then you should click on this value in the left-hand window, and then click the > button to move it into the list of Selected protocols. Once the value appears in the right-hand window, click OK.

5. Click to apply the changes. You must restart the server engine for the changes to take effect.
6. Remember that you also need to confirm that your client computers are configured to use TCP/IP, as well. Please refer to Chapter 18, Client Network Configuration.

   Enabling Multihomed TCP/IP Support

Follow this procedure when your server machine has two network cards installed.

1. From the Start menu, choose Programs4Pervasive.SQL V84Control Center.
2. In the PCC window, double-click on Pervasive.SQL Engines to display a list of the engines registered with PCC.

   If the engine you want to configure is not listed, right-click on Pervasive.SQL Engines and choose Register New Engine.

3. Double-click on the icon representing your target engine. Double-click Configuration. Login if prompted. Double-click Server. Click on Communication Protocols. In the window to the right, double-click on TCP/IP Multihomed.
4. If you want the server engine to listen for client connections on both network cards, change the value to On. If you want the server engine to listen on only one card, change the value to Off. Click OK. If you only have one network card, this setting is ignored.
5. If your server computer has two network cards, and you set the value of TCP/IP Multihomed to Off, you must double-click the setting Listen IP Address and specify the TCP/IP address of the card you want the server engine to listen to. If you do not specify an IP address, the server engine will not receive communications from either network card.
6. Click to apply the changes. You must restart the server engine for the changes to take effect. You do not need to make any changes to client settings.
