NOVELL TECHNICAL INFORMATION DOCUMENT
TITLE: SAA010.EXE, DOS Client LUx API Support
DOCUMENT ID: TID250352
DOCUMENT REVISION: A
DATE: 09AUG94
ALERT STATUS: Yellow
INFORMATION TYPE: Symptom Solution
README FOR: SAA010.EXE
NOVELL PRODUCT and VERSION:
NetWare for SAA 1.3B
NetWare for SAA 1.3A
NetWare for SAA 1.3
ABSTRACT:
SAA010.EXE provides all versions of NetWare for SAA 1.3 with DOS Workstation
API support to use SNA communications for secondary dependent logical units
using the LU 0, LU 1, LU 2, and LU 3 protocols. SAA010.TXT does not provide
instructions regarding the writing of LUx applications. If you wish to write
applications contact Novell Marketing for assistance at the address shown in
SAA010.TXT.

SYMPTOM
GENERAL
1. RUI or SLI verbs may not post as complete.
2. The NWSAA_INIT verb was not checking all eight bytes of the
profile name.
3. A new return code was added to LUX.
4. Nearest server determination
5. RUI_WRITE problems
6. Applications that poll the primary return code may fail.

INSTALLATION INSTRUCTIONS
1. Create a directory in the SAA server. (SYSTEM\NWSAA\LUX\DOS)
2. Copy the files the files in SAA010 into the directory.
SOLUTION SPECIFICS
A. GENERAL
1. RUI or SLI verbs may not post as complete, even though a trace run at the
server shows the response returned to the client (eg. the trace obtained via
CSSTATUS may show an RUI_READ request
RET TIME:00:00:00:60 VPL= RUI_READ
000000 .........................
followed by the response returned to the client
REQ TIME:00:00:00:60 VPL= RUI_READ
000000 ...................
but the verb remains stuck IN_PROGRESS
2. The NWSAA_INIT verb was not checking all eight bytes of the profile name.
When the first four bytes were not unique, LUX returned a primary return code
of SV_STATE_CHECK and a secondary return code of SV_SESSION_ALREADY_OPEN in
error.
3. A new return code was added to LUX when NWSAA is unloaded or a hard reset
LU is performed at the server: Primary return code LUX_SESSION_FAILURE and
secondary return code LUX_NWSAA_SESSION_RESET.
4. For DOS only, if the nearest server cannot be determined within fifteen
seconds, THE SLI_OPEN or RUI_INIT fails.
5. RUI_WRITE with no data was being rejected with a parameter error, but is
valid (eg. RH with change direction )
6. Applications that poll the primary return code may fail. The return codes
were set prematurely when the data size exceeded the packet size
(approximately 500 bytes for DOS and 4000 bytes for NLM) Applications that use
LUX callback posting are not impacted.
TO RUN LUx
----------
Prior to running a LUx DOS application:
- the LUX TSR may be loaded via "CCSLOAD LUX".
or
- the application may be allowed to load the TSR.
In either case, LUx dynamically links to the code in the TSR when the
application makes the initial load request.
The EXEs provide LUx services to LUx applications. They work together at the
DOS Client to communicate with a host system.
TO UNLOAD THE LUx TSR
---------------------
Following the completion of LUx applications:
CCSLOAD /U LUX
Files Description
----- -----------
SYSTEM\NWSAA\LUX\DOS\CCSLOAD.EXE LUx loader
SYSTEM\NWSAA\LUX\DOS\LOADBASE.EXE Lux loader TSR
SYSTEM\NWSAA\LUX\DOS\LUX.EXE LUx API TSR
SYSTEM\NWSAA\LUX\DOS\LUX.LIB LUx API Library (linked with
application)
The EXEs provide LUx services to LUx applications. They work together at the
DOS Client to communicate with a host system.
Developing LUx Applications
---------------------------
The LUX library is used by the application developer to build LUx
applications. It is not required at the DOS Client to run the application.
A LUx application is linked with the Novell LUX.LIB when the application is
developed.
The LUx Library provides the following LUx entry points:
SETUP_NWSAA - Setup APIs for loading,linking & unloadingsoftware.
SVC_NWSAA - Service APIs for Initializing and Terminating NetWare for SAA
LUx sessions, and for the Convert function.
LUX_NWSAA - LUx APIs
- Request-unit interface (RUI)
- Session-level interface (SLI)
