MORE INFORMATION

Sample VTAM and CICS Parameters for Independent LU 6.2.

The following sections show some sample VTAM and CICS configurations for independent LU 6.2. For more information, see the appropriate IBM manuals, or access the IBM APPC forum on CompuServe; to do this, at any ! prompt, type go appc. One document available through the IBM APPC forum is MPCONT.ZIP, a multi-platform LU 6.2 configuration guide containing information about CICS and VTAM.

Sample VTAM Parameters for Use with LU 6.2.

The lists in this section show sample VTAM parameters that might be used for communication using independent LU 6.2. The underlined values correspond to values specified in SNA Server Admin.

In the preceding list, the mode named APPCMODE is an example of a mode configured for use with LU 6.2. (Note that the mode named SNASVCMG is included in SNA Server, since it is required for parallel session support; it does not need to be configured in SNA Server Admin.) Sample CICS Configuration Screens for Use with LU 6.2 The following series of screens show how CICS could be configured for independent LU 6.2 through VTAM. In the first screen, the underlined values correspond to values specified in SNA Server Admin. _________________________________________________________________

The following table shows the SNA Server parameters and values that correspond to the preceding sample CICS parameters: 

SNA Server Parameter         Sample value           CICS parameter

LU Name for Local APPC LU      LOCLU1               Sessions

Mode name                      APPCMODE             MOdename

Parallel Session Limit         250                  MAximum

Partner Min Contention         125                  MAximum

Max Receive RU Size            00521                SENDSize
in the mode 

Max Send RU                    00521                RECEIVESize
in the mode 

LU Name for Remote APPC LU     CICSLU               APPLID
In the sample CICS screen, the parameter called MAximum has two values, 250 and 125, separated by commas. The first value (250) is the parallel session limit. The second value (125) is the host minimum contention winner limit. On the SNA server, this corresponds to Partner Min Contention Winner Limit in the mode. In addition, since the host is the contention winner on 125 sessions (out of a total of 250), then SNA Server should be configured as the contention winner on the remaining 125 sessions. In this case, the SNA Server mode would have the following values: * Parallel Session Limit 250 * Minimum Contention Winner Limit 125 * Partner Min Contention Winner Limit 125 * Automatic Activation Limit 0

The remaining screens in this section show more information about how CICS could be configured for independent LU 6.2 through VTAM. _________________________________________________________________
