gtpm1m2i | TPF V4R1 Migration Guide: 3.1 to 4.1 |
This chapter describes the changes (including system generation
changes) that you may need to make in Systems Network Architecture (SNA)
communication to migrate to the TPF 4.1 system.
There are changes in the following areas:
- Setting shutdown levels based on the size of the input list
(rather than core block levels)
- Defining SNA resources
- Generating the SNA table
- Modifying SNA network definitions
- Changing all references to the network addressable unit (NAU)
program (COVX) to use the INQRC macro
- Generating the SNA table
- Consolidating TPF/APPC application program names
- Converting network node names
- Understanding 3-byte resource identifier (RID)
- Reviewing changes to TPF Advanced Program-to-Program Communications
(TPF/APPC),
if you want to use this support. If you do not want to use this
support, set SNAKEY parameters MAXSCB and MAXCCB to 0, and do not use the
presentation services
(PS) layer provided in the TPF system.
See the TPF ACF/SNA Data Communications Reference
for more information about SNA SNA communication. Also see Operating Environment Requirements and Planning Information for more information about the operating environment for
SNA-based communication.
