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
6.2 API 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
4.0 or 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.
