# Enabling Client/Server Applications

Personal Communications support for APPN end nodes lets you take advantage of APPN networks. An APPN network allows automatic locating of partner applications and dynamic, optimized route selection. These features allow workstations to communicate more flexibly with other systems in the network.

Personal Communications also provides support for 32-bit APPC and CPI-C application programming interfaces (APIs), which provide convenient ways for 32-bit client application programs on your workstation to communicate with those on other workstations.

## Configuring a Node

Before you can take advantage of the client APIs and communicate with other application programs, you first need to configure Personal Communications as an SNA end node.

To configure the SNA node:

1. From the Start menu, click Programs -> IBM Personal Communications -> SNA Node Configuration.

   The Personal Communications SNA Node Configuration window appears.

2. Select the necessary Configuration Options in the order listed on the window.

   To select an option, click it and then click New.

   For each option, enter the appropriate information on the configuration panels. Most required information is listed on the Basic page. Click OK to complete the option. Click Help if you need more information about the individual parameters.

3. Click File -> Save or Save As.
4. Type the file name and then click Save. Note that you can choose the file type and where to save this file. The default file type is .ACG and the default location is the system-class application data directory.
5. Click File -> Exit.

Tip
If you have more than one configuration file, you can apply additional configuration files to an active node. Refer to the help in the SNA Node Operations section of the product for details.

## Starting the SNA Node

1. To start the SNA node, from the Start menu, click Programs -> IBM Personal Communications -> SNA Node Configuration.

   The Personal Communications SNA Node Operations window appears.

2. Click Start Node from the Operations menu.

   The Select configuration file to use window appears.

3. Double-click the configuration file (.ACG) that defines the node you want to start.

Note:
  Another way to start the SNA node is to use the command line. The command to use is CSSTART. For the proper syntax, refer to Administrator's Guide and Reference.

## Stopping the SNA Node

1. To stop the SNA node, click Programs -> IBM Personal Communications -> Administrative and PD Aids -> SNA Node Operations.

   The Personal Communications SNA Node Operations window appears.

2. Select a resource in the Alias column.
3. Click Stop Node from the Operations menu.

Note:
  Another way to stop the SNA node is to use the command line. The command to use is CSSTOP. For the proper syntax, refer to Administrator's Guide and Reference.

## APING Requirements

If you wish to run the Check Connection (APING) utility provided with this package to an iSeries, eServer i5, or System i5 running OS/400 V3R1, you must install PTF MF10808 on the iSeries, eServer i5, or System i5 first. If this PTF is not installed, then errors with sense codes of 080F 6051 and 1008 201D will occur.
