How SNAX/APN Differs From SNAX/CDF
The following is a list of features that are supported in SNAX/CDF but not in
SNAX/APN. If you plan to use any or all of these features with applications migrating
from SNAX/CDF to SNAX/APN, or if SNAX/CDF applications will be running across
SNAX/APN, your applications must be modified.
•
Support for the Japanese character sets
•
An interface for a user-written virtual route selection process
•
The Session Initiation Exit process
•
The SNAX/CDF binary synchronous communication (BSC) 3270 interface
•
Encryption support
Table A-2 lists the functions that are available with the CRT protocol in SNAX/CDF but
are not supported in SNAX/APN.
Support of INITOTHER and TERMOTHER Requests
The INITOTHER and TERMOTHER requests are not supported by the SNALU
interface of SNAX/APN as they are by SNAX/CDF. If a Tandem application sends an
INITOTHER or TERMOTHER request, it will be rejected with a file system return
code 2.
