HP LU 6.2 API provides

•High-level Intrinsics: HP 3000 program- mers can use a set of high-level intrinsics to implement program-to-program communica- tion in an SNA network.

•Support for Major Languages: Application programs on the HP 3000 can be written in COBOL II, Transact, or Pascal. For LU 6.2 API/iX, C language applications are also supported.

•Support for IBM Applications: HP LU

6.2API supports Mapped Conversations with CICS in an MVS or DOS/VSE environ- ment and Mapped Conversations with VTAM in an MVS environment. With MPE/iX Release 4.0 or later, HP LU 6.2 API/iX supports Mapped Conversations in an OS/400 environment.

•Multiple Sessions: An HP 3000 applica- tion program using LU 6.2 API/V intrinsics may have up to 8 LU-LU sessions running simultaneously. With MPE/iX Release 4.0 or later, an HP 3000 application program using LU 6.2 API/iX intrinsics may have up to 256 LU-LU sessions running simultaneously. Each session is responsible for a separate communication task or for adding additional bandwidth to a single communication task.

•Peer-to-peer Connectivity: With MPE/iX Release 4.0 or later, LU 6.2 API/iX provides peer-to-peer connectivity to an IBM AS/4000 over Node Type 2.1. an HP 3000 may establish LU-LU sessions with an IBM AS/400 over Node Type 2.1 without having to go through a mainframe node.

•Parallel Sessions: With MPE/iX Release

4.0or later, LU 6.2 API/iX provides support for parallel sessions over Node Type 2.1. An HP 3000 may establish multiple, simultane- ous LU-LU sessions over a single LU-LU pair over Node Type 2.1.

•Support for Remote Attach: Remote Attach is the ability of a remote LU 6.2 application to start running and begin com- munication with it.

•Compatibility with Other SNA Services: The HP LU 6.2 API is completely compatible with other SNA services offered

for the HP 3000. These HP SNA products may all be running simultaneously over the same SNA Link/V, SNA/SDLC Link/iX, SNA/Token Ring Link/iX* or SNA/X.25 Link/iX to the SNA network. The SNA Link products manage the physical link to the IBM host and implement protocols in the lower three layers of SNA.

Note: HP LU 6.2 API/iX supports Native- mode HP 3000 applications only.

•Trace Facility: An easy-to-use trace facili- ty that allows HP 3000 application program- mers to track all LU 6.2 intrinsic calls and executions within applications being devel- oped, serving as a valuable debugging aid during program development.

•Logging Facility: A comprehensive logging facility that records all online LU 6.2 API session messages to aid in problem identifi- cation and resolution.

•User Controlled Sessions Management from Program or CI (CNOS): With MPE/iX Release 5.5 Express 7 or later, or MPE/iX Release 6.0 Express 1 or later, Programmatic or interactive user-controlled session management allows users to change session limits (over Node Type 2.1).

•Enhanced Communication Rates: The maximum datacomm line speed between the HP 3000 and the IBM mainframe host is 56 KB/s on MPE V and 16 MB/s on MPE/iX.

•Efficient and easy-to-program problem detection and recovery procedures.

•As with all HP SNA services, customized error and help facilities are provided.

•X.25 Connectivity: HP LU 6.2 API/iX can communicate to an IBM mainframe over an X.25 connection. The SNA/X.25 Link/iX product (HP 30298A) can be used in place of SNA/SDLC Link/iX, or SNA/Token Ring Link/iX* but SNA/X.25 Link/iX emulates a Type 2.0 node, not a Type 2.1 node. Therefore if you run LU 6.2 API/iX over SNA/X.25 Link/iX, you cannot communicate, peer-to-peer with a Type 2.1 node like an IBM AS/400.

*SNA/Token Ring Link/iX requires MPE/iX release 5.0 or later.
