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.

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

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 The remaining screens in this section show more information about how CICS could be configured for independent LU 6.2 through VTAM. _________________________________________________________________ OVERTYPE TO MODIFY                 CICS RELEASE = 0330 CEDA ALter SESSION PROPERTIES SESSPriority ==> 000             0-255 Transaction   : OPERATOR DEFAULTS OPERId        : OPERPriority  : 000              0-255 OPERRsl       : 0                            0-24,...
