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.

is the correct value to use with independent LU 6.2 LUs.

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

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.
