Sample Configuration for SNA CTC

The CTC box in Figure 21 represents channel-to-channel support; for example, a 3088 communication unit or an Enterprise Systems Connection (ESCON) channel operating in CTC mode.

Sample Configuration for SNA CTC and PU 2.1 for a Loosely Coupled Complex

Figure 22 shows a TPF loosely coupled complex attached to the subarea network in three ways:

Consequently, the VTAM definition statements must define three TPF images. Both the same network and cross-network definitions require CDRM and CDRSC statements to define the TPF processor and its resources. The PU 2.1 image is derived by VTAM from the NCP generation deck.

The CTC box in Figure 22 represents channel-to-channel support; for example, a 3088 communication unit or an Enterprise Systems Connection (ESCON) channel operating in CTC mode.

Sample Configuration for a 3745 Resource, Model 410

Figure 23 shows 2 central control units (CCUA and CCUB).

Figure 23. Sample Configuration for a 3745 Resource, Model 410


Sample ALS Deck

The following is a sample ALS deck for the configuration in Figure 23.

ALSA      ALS      CLU=CLUAA001,ALSQN=20
XALSA     ALS      ALSQN=20

Notes:

  1. ALSA and XALSA are the PU names coded in the NCP generation for the NCPA and NCPB central control units (CCUs) respectively.

  2. CLUAA001 is the LU name coded in the NCP generation under both ALSA and XALSA.

  3. CLUAA001 is not required on XALSA for CCUB, which is the backup CCU. With 3745 running in fallback mode, CLUAA001 can be switched to XALSA without changing the LU name.

Sample NCP Generations for NCPA and NCPB

Figure 24 shows an NCP generation for 3745-410 channel adapter definitions that are required for fallback mode.

Footnotes:

1
This CDRM statement assigns the subarea of the local TPF processor. This subarea is the same for both the native VTAM network and for the TPF network.

2
This OSTG statement represents the CTC path to VTAM. From the point of view of the TPF system, each VTAM host appears as two nodes: one node attached by a CTC and another node attached by an SNI NCP. The subarea specified on the CTC statement is for the subarea of VTAM in its network.

3
The subarea of a VTAM host reached through an SNI NCP is used to group the resources in that domain. The subarea value is not used as the VTAM domain's network address.

4
Local SNA 3270s channel-attached to a VTAM system adjacent to the TPF system are supported across a SNA CTC with the constraint that the 3174 and VTAM buffer sizes are defined to ensure that only RH chaining is used. This is because the TPF system does not support both TH and RH chaining on an LU session.

5
The subarea specified on the CTC statement allows the TPF system to dynamically discover the name of the CTC link station when the remote processor initiates the XID procedure. That is, the XID data contains the subarea of the sender and this value is used to locate the corresponding CTC link station definition.

6
These CDRM statements assign the subarea of the local TPF processors. These subareas are the same for both the native VTAM network and for the TPF network.

7
These statements define the TPF CLUs for the Logon Manager. The LU names are arbitrary. In this example CLUB01 and CLUC01 are for the CTC connections to Logon Manager LOGM1, CLUB02 and CLUC02 are for the CTC connections to LOGM2, and CLUB04 and CLUC04 are for the ALS connections to LOGM2.
