gtpm1m2m | TPF V4R1 Migration Guide: 3.1 to 4.1 |
In the TPF 3.1 system, if you wanted to access a TPF application program through both a gateway network control program (NCP) and an adjacent link station (ALS), you could use a single application program name by using VTAM interpret tables and gateway aliasing. However, if you also wanted to access the application program through a channel-to-channel (CTC), you had to define two application program names with two SIP MSGRTA macros and two corresponding VTAM definitions. The TPF 4.1 system solves this problem for CTC connections by adding suffixes to a single TPF/APPC LU name and creating a new alias name for each CTC connection as is already done for ALS connections. You can now code a single MSGRTA macro. Then you must code VTAM CDRSC definitions associated with the TPF CTC CDRM for the TPF application program alias names that are suffixed with the TPF CPU ID and the CTC qualifier number. Then you can change your remote host node application programs to specify the single generic name in their session requests.
