APPC/PC Configuration
TERMTYPE=LUTYPE62,
NETNAME=luname,
:
CICS selects the session parameters based on the TERMTYPE parameter.
Every mode name supplied when defining LU 6.2 links to CICS must be matched by a
VTAM LOGMODE entry name.
APPC/PC Configuration
SNAX/APC can communicate with APPC/PC (LU 6.2 for the IBM Personal Computer).
APPC/PC requires little configuration.
The IBM manual Advanced Program-to-Program Communication for the IBM Personal
Computer Installation and Configuration Guide describes how to configure APPC/PC
for an IBM Token-Ring Network or SDLC.
The IBM manual Advanced Program-to-Program Communication for the IBM Personal
Computer Programming Guide describes how to define LUs and PUs.
To define an LU under APPC/PC, the operator uses the ATTACH_LU control verb.
Before issuing ATTACH_LU, the operator needs to know some information about the
partner (SNAX/APC) LU. Table 2-1
correlates the SNAX/APC parameters and the
ATTACH_LU parameters.
Note that while the LU 6.2 definition states that session segmentation support is a
negotiable parameter (byte 6 - bit 0), SNAX/APC does not support the negotiation of
this parameter. SNAX/APC always operates as if the remote LU supports segmentation.
SNAX/APC can send segmented RUs if MAXOUTRUSIZE + TH (Transmission Header
is 6 bytes) is greater than the PU RECSIZE (specified in SCF). If your configuration of
APPC/PC does not support segmentation, you must ensure that MAXOUTRUSIZE +
TH is less than PU RECSIZE.
VTAM Definition Parameters
The VTAM definition parameters described below relate to establishing sessions
between CICS and SNAX/APC.
MODE TABLE ENTRY:
Mode tables contain mode entries that in turn contain session parameters for the BIND
request.
