Installation Instructions:
STOP!!!
Do not simply copy these files!
You MUST follow the installation instructions below exactly!!
NOTE: CSINSTAL must be used to install this PTF.
NOTE: Version 1.2 of NetWare for SAA must be installed before this PTF is
installed.
NOTE: In addition to the installation instructions, the PROBLEM/SOLUTION
DETAIL section includes instructions which must be followed for some
fixes and new features to be implemented.
1. If the Communications Executive is active do a CSDOWN from the CS>
prompt.
2. Unload the Communications Executive by typing "UNLOAD COMMEXEC" from
the server (:) prompt.
3. Install PTF 428
A. If the server has a hard drive:
- Copy PTF 428 onto the SAA servers hard drive.
- At the comm server (:) prompt type LOAD (followed by the path to
the \CSINSTAL directory) For example: LOAD C:\CSINTAL
- Chose the option to "Update Netware Communication Service".
- Confirm that Netware for SAA should be updated.
- Exit CSINSTAL and reload the COMMEXEC and Host profiles.
B. If the server does not have a hard drive, but does have a high
density 3.5" drive:
- Copy PTF 428 onto a 3.5" high density disk.
- Place the disk into:
- The server's A drive.
- At the comm server (:) prompt type "LOAD A:CSINSTAL A".
OR
- The server's B drive.
- At the comm server (:) prompt type "LOAD B:CSINSTAL B".
- Chose the option to "Update Netware Communication Service".
Be patient, it may take more than 10 minutes for update to complete.
- Confirm that Netware for SAA should be updated.
- Exit CSINSTAL and reload the COMMEXEC and Host profiles.
4. If you are using PC Support with a SDLC connection:
A. Bring up the SNA SDLC Configuration Panel and change the PU2.1
link station role to SECONDARY.
B. On the AS400
- In the Controller Description, change the Data Link role to
SECONDARY.
- In the Line Description change the Data Link role to PRIMARY.
Failure to do this will result in the link not being established.
5. ONLY IF three AS400s are connected.
Configure CONFIG.PCS as in the EXAMPLE below. Note that the TRLI
parameters contain the three system names, followed by their local
adapter addresses contained within the line configuration of the
associated AS/400.

6. ONLY for Token Ring Connection.
Put the following statement in AUTOEXEC.NCF prior to loading the SNA
Service Profile.
LOAD ITRNPS /RT=n
"n" is a number from 1 to 5, with each increment equaling 5 seconds. As
ITRNPS tries 6 times before dropping the connection "LOAD ITRNPS /RT=5"
would set the Response Timer to the maximum wait of 30 seconds.
Patch History:
PTF 428 supersedes all prior NetWare for SAA v1.2 PTFs, including PTF 384
which was the immediately preceding PTF.
Solution Specifics:
Duplicate any symptom cause solution fields required.
1. USING LU6.2
1A. The server hung when a Transaction Program issued a
MC_SEND_ERROR after issuing a MC_RECEIVE_WAIT.
1B. Server Abend
- When a Transaction Program referenced a zero-location
pointer.
- When two workstations constantly loaded and unloaded
Transaction Programs.
1C. Transaction Program unable to establish conversation.
1D. A STATE_CHECK error was received when a MC_TEST was issued while
in SEND state.
1E. NWSAA server abend with "out of Correlator ID".
1F. A SEND_ERROR verb generated massive amounts of errors in
SYSTEM.LOG.
1G. Userids and passwords supplied by LU6.2 applications were not
passed to the host. They will now be passed to the host, allowing
conversations to be established.
1H. "GPPE error in SNAP" should no longer be received when using two
site information records with CPIC API.
1I. When using XCOM 6.2 file transfer a 12FF and 12E1 were sent in
the data stream and hung the workstation.
1J. A number of problems have been corrected which occurred in both
PU2.0 or PU2.1 configurations.
2. GENERAL
2A. When Netware for NFS and NetWare for SAA were installed on the
same server, a UNIX client was not able to connect to NetWare for
SAA through a TCP/IP connection. The problem was caused by Netware
for SAA and NetWare for NFS print services both trying to use port
515 for TCP/IP connection. CMTCP.NLM has been changed so Netware
for SAA will now use TCP/IP port 1366.
2B. A 3270 LAN workstation will now be able to connect without
problems if more than 29 Comm servers are on the Network.
2C. The error message, "Alloc short term memory allocator request
exceeded the configuration" was sometimes received at the SAA server
and the SAA server subsequently failed. There are two possible
causes for the error message:
- Too little RAM in the server. Solution: a minimum of 6M RAM
- Corrupted Memory Pointers. Solution: apply this PTF
2D. 3270 LAN Workstation for DOS sent a packet with an invalid
source identification field to Netware for SAA during session
startup. When the SAA server received such a packet it would abend
with the error message, "General Protection Processor Exception
Running Process: Streams Q Runner Process".
IMERC.EXEs dated 5/18/92, or later, include a modification so the
workstation will no longer send a packet that contains a corrupted source
ID field. THEREFORE this problem will not be solved unless your 3270 LAN
Workstations for DOS are at version 2.02 (or higher) AND with an
IMEREC.EXE dated 5/18/92 or later. Contact Attachmate in order to secure
a such an IMEREC.EXE02 and in order to upgrade to V2.02.
3. WITH TOKEN RING CONNECTION
3A. The connection would not establish and the server displayed the
error message; "Link Disconnected" because, SAA responded with "XID
negotiation error byte 9 bit offset 4" to an "00 Exchange State Not
Supported" in XID from the host.
3B. SAA sets a response timer for each frame that it sends to an
IBM Host and disconnects the link to the Host (displaying a message
at the CS Console) if a response is not received before this timer
expires. The response can be slow in large WAN environments,
resulting in a loss of connection. After installing the new
ITRNPS.NLM by following Installation Instruction #5 you will have
the ability to adjust the response timer so that SAA will wait
longer for a Host response before disconnecting the link.
To do so, put the following statement in AUTOEXEC.NCF prior to loading
the SNA Service Profile.
LOAD ITRNPS /RT=n
"n" is a number from 1 to 5, with each increment equaling 5 seconds. As
ITRNPS tries 6 times before dropping the connection "LOAD ITRNPS /RT=5"
would set the Response Timer to the maximum wait of 30 seconds.
4. Accessing an AS/400 via PC Support
4A. NWSAA.NLM modified to allow independent LUs from 0-81 to be
used.
4B. With NetWare for SAA on a NetFrame server; after the router
(STRNRTR) starts and the Workstation Function (WSF) loads, the
emulation screen is blank except for the Operator Information Area
(OIA).
4C. The length of the PIU was incorrect causing one byte of the
file to be overwritten. This caused large file transfers to fail
with the message, 9999 Unexpected Code Error.
4D. Support for the connection of three AS/400s on a Token Ring
network did not work because the third Mac address overlaid the
second Mac address. The ITRNPS.NLM included with this PTF adds
support for the connection of three (3) AS\400s. See installation
step #5 above.
4E. If "A" was pressed to ADD A STUDENT when using Schools
Administrative Student Information (SASI), from Macro Educational
Systems, the workstation locked with COMM ERROR 001 00000018.
4F. High server utilization rates were observed at some
installations.
4G. An incorrectly entered password could not be corrected during
STRNRTR.
4H. Problems were experienced running JD Edwards applications.
4I. Recognition of the System Name has been modified so that if the
AS/400 system name is less than 8 characters, the workstation will
no longer hang when Rochester Software Connection's ShowCase Vista
software is invoked when the system is selected.
4J. RTRMAP from IBM, maps requests from "Extended DOS PC Support"
functions into requests recognized by the NetWare Router for AS/400
PC Support. When RVMRTR is used to remove the Router it frees the
memory that RTRMAP was using but did not display a message.
(corrected with additional APPC verb support)
NOTE: RTRMAP is in a patch available from IBM
- V2 Release 1 requires IBM PTF SF09653
- V2 Release 1.1 requires IBM PTF SF09654
- V2 Release 2 contains the corrected code
4K. Additional APPC verb support has been added so that:
- When running Remote SQL (RMTSQL) from IBM with PC Support
Extended, it will no longer fail with "error on start 32"
- After starting Workstation Function (WSF) from PC Support
Extended, and signing on at the Sign On Screen, the monitor will no
longer go blank with the exception of two lines at the bottom:
PCS6545 0A 0001 000000A1 00 (first line)
The WSF status line (second line)
- When the Remove PC Support (RMVPCS) command is used to release the
memory of selected PC Support Functions, it will now remove the
NetWare Router for AS/400 PC Support.
5. With SDLC Connection
5A. R3SDLC has been modified so that:
1) The server will no longer abend with a GPPE error if the server
is unloaded and reloaded while a leased line link is up.
2) The message "Data larger than MAX SDLC frame size, caused by
checksum error" will no longer display on the console. Instead, the
"receive packet too big count" in MONITOR will be incremented.
NOTE: The error can be caused by a Network Interface Card with shared RAM
interfering with the SDLC adapter. We suggest trying another brand of
LAN card.
3) The profile configuration will now determine if RTS is held high
or toggles.
4) Workstations will no longer hang if the SAA adapter board
receives an invalid interrupt.
5) Frames will no longer be resent unnecessarily. The retrys
degraded performance.
6) 'Ghost', "Receive Packet Miscellaneous Errors" will no logged be
logged in the Monitor Utility, when in fact, not occurring.
7) Abort Frames will now be properly handled. Abort Frames from the
Host were detected but not handled correctly. A RESEND was
requested, but the bad frame not flushed. Instead, it was added to
the resent Frame and passed on to the workstation. This caused the
display screen to show the bad frame data. In structured field mode
the length of field came out wrong, and a sense code was returned to
the Host.
In the case of file transfer (RECEIVE.EXE) the transfer aborted.
8) Full duplex communication will now be properly supported. When
running Full Duplex the number of SDLC frames transmitted from the
Host did not match the number received.
NOTE: To implement a Full Duplex line use a statement like the
following Line Macro example:
N11L001 LINE ADDRESS=(001,FULL)
ISTATUS=ACTIVE
5B. SDLCPS was modified:
1) To improve ECB management. This will sharply reduce the
number of sites receiving the console message "No ECB
Available".
2) So that NetWare for SAA will now respond with a UA
(Unnumbered Acknowledge) when FEP sends a DISCONNECT (53).
Failure to send a UA caused the Link to not establish.
3) The Comm Server will respond with only one UA when the Host
sends two SNRM's in a row. The Comm Server was responding with
two UAs which caused the Host to send a disconnect to the Comm
Server. This resulted in the connection to the Host never
being established.
NEW SDLC FEATURE
R3SDLC.LAN now supports Auto Disconnect. The firmware disables the
receiver when it turns off DTR.
SDLC CHANGE
R3SDLC.LAN will no longer send a message to the console "No DSR from
modem, please dial to host. Need to use Novell cable". When the R3 SDLC
cable is disconnected and the R3 driver attempts to connect to host.
Instead, the DSR Inactivity Count under Custom Statistics for the R3SDLC
driver will increment the counter by one every time the driver attempts
to make a host connection without the cable attached.
