COMPAQ DIGITAL SNA APPC/LU6.2 Programming Interface for OpenVMS, Version 2.4 AV-KQ77F-TE Dear Customer: This kit contains the DIGITAL SNA APPC/LU6.2 Programming Inter- face for OpenVMS, Version 2.4, software and user documentation. Please check the bill of materials to see that all the items listed are in your distribution kit. If any item is missing or damaged, please contact your Compaq representative. The DIGITAL SNA APPC/LU6.2 Programming Interface for OpenVMS, V2.4 product supports the OpenVMS VAX Version 6.2, 7.0, and 7.1 and OpenVMS Alpha Version 6.2, 7.0, and 7.1 operating sys- tems and their associated License Management facility (LMF) requirements. Description The DIGITAL SNA APPC/LU6.2 Programming Interface for OpenVMS product is a layered software product that allows user-written applications running on suitably configured OpenVMS systems, ei- ther within a TCP/IP or DECnet network environment, to exchange messages with cooperating applications on an IBM host. Access between the cooperating OpenVMS and IBM applications is via one of the following products: o DIGITAL SNA Peer Server o DIGITAL SNA Domain Gateway for Channel Transport o DIGITAL SNA Domain Gateway for Synchronous Transport o DECnet SNA Gateway for Synchronous Transport o DECnet SNA Gateway for Channel Transport o DIGITAL SNA Access Server for Windows NT o OpenVMS SNA Features The APPC product is a set of subroutines called by OpenVMS programs that act as LU6.2 transaction application programs. These subroutines allow a OpenVMS transaction application to: o Activate and deactivate sessions o Allocate and deallocate LU6.2 basic and mapped conversations o Send and receive data o Request confirmation and confirm transactions o Send and receive error information o Define remote LU, mode, and transaction program parameters o Supply program initialization parameters o Supply session-level security and conversation-level security o Allocate a conversation in response to an incoming allocation request Installation Register and load the product's PAK using the OpenVMS License Management Facility before you begin installation. Refer to the OpenVMS License Management Utility manual for complete licensing information. To install, enter the following command: $ @SYS$UPDATE:VMSINSTAL SNALU62024 device-name OPTIONS N Compaq recommends that you read the Release Notes for any tech- nical issues before you begin installation.
