Chapter 2: CCIAPPC Configuration

CCIAPPC is supported on Windows 95, Windows 98 and Windows NT systems only.

2.1 CCI Support for APPC

2.1.1 CCI Support Modules for APPC

In order to enable CCI support for APPC one executable module is provided:

2.1.2 Pre-requisite SNA Support for CCIAPPC

CCI support for APPC prerequisites the APPC support provided by a third-party SNA product. CCI uses the Windows Common Programming Interface for Communications (Windows CPI-C) to communicate with other systems using APPC. The SNA products supported by CCI on 32-bit Windows platforms are listed in the APPC Configuration section.

2.2 APPC Configuration

2.2.1 APPC Product Configuration Guides

The following configuration guides describe configuration of the SNA products supported for use with CCIAPPC on 32-bit Windows platforms.

These SNA products require that a network adapter and device driver have been installed which will be used to communicate with other systems using SNA protocols. In a Local Area Network (LAN) environment you will need to have installed a LAN adapter and 802.2 Data Link Control device driver.

These guides describe how to install a DLC device driver and configure APPC for CCI communication in a LAN environment using 802.2 Data Link Control (DLC). However, you may want to use another network configuration, such as SDLC, X25 or Channel attachment, for example. Please refer to the documentation provided with the SNA product for information on configuring the SNA product in network configurations other than a LAN. In such cases, although the SNA Connection configuration will differ, the APPC configuration will be identical to that described for a LAN environment.

2.3 Application Configuration

CCIAPPC Client/Server applications use the CCI Server Name and Machine Name parameters to enable the CCI Client to specify the CCI Server with which to communicate.

The CCI Server identifies itself using the Server Name parameter. The CCI Client specifies the partner CCI Server using the Server Name and Machine Name parameters.

2.3.1 CCIAPPC Server Name

The Server Name parameter specifies the APPC Local LU Name and Transaction Program Name (TP Name) to be used by the CCI Server.

The format of the Server Name is as follows:

<Local LU Name>.<TP Name>
E.g., CCISERV.CCITPN01

The TP Name is optional and if absent the Local LU Name is also used as the TP Name.

The Server Name parameter specifies the APPC Partner LU Name (also known as the APPLID on a host system) and TP Name of the partner CCI Server. The Partner LU Name (or APPLID) must match the Local LU Name (or APPLID) and TP Name as specified by the CCI Server (see above).

The format of the Server Name is as follows:

<Partner LU Name>.<TP Name>
E.g., CCISERV.CCITPN01

2.3.2 CCIAPPC Machine Name

The Machine Name parameter specifies the APPC Local LU Name for the CCI Client and and APPC Mode Name to be used by the Client to communicate with the Server.

The format of the Machine Name is as follows:

<Local LU Name>.<Mode Name>
E.g., CCICLI.CCIMODE

The Mode Name is optional and if absent the default APPC Mode #INTER is used.

NOTE: APPC LU Names, TP Names and Mode Names can be up to 8 characters in length.

2.4 Troubleshooting

This occurs when the Local LU has not been properly specified for the CCIAPPC Client. Refer to the section entitled Enabling CCIAPPC To Find The Local LU in the appropriate configuration guide in the APPC Product Configuration Guides section for the SNA product in use.

For other problems refer to the section entitled Error Reporting and Diagnostics in the appropriate configuration guide in the APPC Product Configuration Guides section for the SNA product in use.
