This is a text description of Figure 9-15, "Relationship between SNAPlus2 Definitions and Host VTAM Definitions".
This figure describes the relationship between sunlink SNA Peer-to-Peer definitions and host VTAM definitions.
The gateway uses the CPI-C interface for SNA communication. CPI-C uses the concept of a Side Information Profile to contain all connection information for a given session.
The Side Information Profile is defined on the Sunlink side of the connection and is used directly by the CPI-C interface. The Side Information Profile contains:
the Local LU name
the session Mode name
the remote Transaction Program name
The Remote Host, or VTAM node, contains:
the Partner LU definition
the Mode table (which defines the specific Mode name)
the network connection definition
Along with the Partner LU definition are SNA-specific resource definitions that are needed by VTAM to complete the network description. These specific definitions are stored by VTAM in the VTAMLST data set. Refer to VTAM-specific documentation for more detailed information.
The figure is a diagram of relationships. Seven groups of rectangles are arranged in two rows of three and one row of one. Consider these seven groups as numbers 1, 2, and 3, from left to right in the upper row, and as numbers 4, 5, and 6, from left to right in the next row, and as number 7 in the bottom row. Group 4 is below Group 1. Group 5 is below Group 2. Group 7 is below Group 6, which is below Group 3.
Group 1 has four boxes aligned vertically, which contain the following entries:
Local LU Definition
Local LU Alias
Local LU Name
...
Group 2 has six boxes aligned vertically. The top box is separated from those below it by an extra horizontal line. The boxes contain the following entries:
Side Information
Local LU Alias
Partner LU Alias
Between the third box and the fourth box is the word "or".
Fully-qualified Partner LU Name
Mode Name
Remote TP Name
Group 3 has three boxes aligned vertically, which contain the following entries:
Mode Definition
Mode Name
...
Group 4 has three boxes aligned vertically, which contain the following entries:
Connection Definition
Connection Name
...
Group 5 has five boxes aligned vertically, which contain the following entries:
Partner LU Definition
Fully-qualified Partner LU Name netname.pluname
Partner LU Alias
Connection
...
Group 6 has three boxes aligned vertically, which contain the following entries:
VTAMLST
APPL Definition pluname APPL... MODETAB=mtname
ATCSTR00 NETWORK=netname SSCPNAME=cpname
Group 7 has two boxes aligned vertically, which contain the following entries:
VTAM Mode Table
mtname MODETAB MODEENT LOGMODE=modename
The figure has nine arrows. Each arrow is connected with tail to one box and head to another box. The arrows are listed below in arbitrary order from top-left to lower-right.
An arrow points from Group 2 box "Local LU Alias" to Group 1 box "Local LU Alias".
An arrow points from Group 2 box "Partner LU Alias" to Group 5 box "Partner LU Alias".
An arrow points from Group 2 box "Fully-qualified Partner LU Name" to Group 5 box "Fully-qualified Partner LU Name netname.pluname".
An arrow points from Group 2 box "Mode Name" to Group 3 box "Mode Name".
An arrow points from Group 3 box "Mode Name" to Group 7 box "mtname MODETAB MODEENT LOGMODE=modename".
An arrow points from Group 5 box "Connection" to Group 4 box "Connection Name".
An arrow points from Group 5 box "Fully-qualified Partner LU Name netname.pluname" to Group 6 box "APPL Definition pluname APPL... MODETAB=mtname".
An arrow points from Group 5 box "Fully-qualified Partner LU Name netname.pluname" to Group 6 box "ATCSTR00 NETWORK=netname SSCPNAME=cpname".
An arrow points from Group 6 box "APPL Definition pluname APPL... MODETAB=mtname" to Group 7 box "mtname MODETAB MODEENT LOGMODE=modename".
