Error connecting SAPinst GUI on AIX 5.3L from Windows XP PC for NW2004s SR2

Hello,

We are trying to install the NW2004s on AIX 5.3/DB2 8.2

We have started the SAPinst GUI on the server and trying to connect to it from our WindowsXP PC.

We are not able to connect to the SAPinst remotely.

We are getting ready to install NW2004s on AIX and DB2 UDB V8.

We start the sapinst as follow on the remote unix server:

cd /software/NW2004S/NWSR2_Installation_Master/IM_AIX_PPC64root@

[gnwux02]:

(/software/NW2004S/NWSR2_Installation_Master/IM_AIX_PPC64)> ./sapinst

[==============================] - extracting... done!

The GUI could not be started because the environment variable DISPLAY

is not set. Please make sure that this variable is defined correctly

or start the GUI on another host (for details please consult the

installation guide)

Starting GuiServer using:

/usr/lib/java -

cp /tmp/install/sapinst_exe.675980.1177373484/JAR/instgui.jar:/tmp/install/sapinst_exe.675980.1177373484/JAR/inqmyxml.jar -

Djava.security.egd=file:/dev/urandom SDTServer config=jar:sdtserver.xml

guiport=21212 sapinsthost=localhost sapinstport=21200

load resource

pool /software/NW2004S/NWSR2_Installation_Master/IM_AIX_PPC64/resourcepool.xml

guiengine: no GUI connected; waiting for a connection on host gnwux02,

port 21200 to continue with the installation

At this point we kick off the SAPinst GUI that was downloaded with the

NetWeaver 2004s on the laptop. The IP address of the Unix server is

entered, an the default port of 21212 is used. Once we click on

the "Log on" button, after about 10 seconds we get the following

message displayed on the GUI:

Could not connect to host 52.99.88.147 on port 21212

java.net ConnectException: Connection refused: connect

No further messages are displayed on the Unix side.

If we change the port on the laptop from 21212 to 21200, the following

message can be seen on the Unix side:

guiengine: login in process...............................

guiengine: login timeout; the client was unable to establish a valid

connection

We also changed the default ports and used 3600 and 3601 for testing

and exact same issue.

We also tried the following to narrow down the problem:

We kicked off SAPinst for Solution Manager 3.2 using the 6.2 SAPinst

GUI for laptop and that was successfull, meaning that SAPinst screen

came up. This indicates that we do not have issues with the ports being

blocked.

This is the output of java -fullversion:

java full version "J2RE 1.4.2 IBM AIX 5L for PowerPC (64 bit JVM) build

caix64142ifx-20061222 (ifix 113727: SR7 + 112603)"

./sapinst -v

[==============================] - extracting... done!

This is SAPinst, version 701, make variant 700_REL, build 860072

compiled on Oct 5 2006, 23:40:13

Also, the user root that is kicking off SAPinst has unlimited for the mentioned values:

ulimit -a

time(seconds) unlimited

file(blocks) unlimited

data(kbytes) unlimited

stack(kbytes) unlimited

memory(kbytes) 32768

coredump(blocks) unlimited

nofiles(descriptors) unlimited

<b>

When we run a 6.4 install in a similar fashion on this box, the connectivity is not an issue and it works on the same ports 21200 and 21212</b>

If anybody has faced this situation please suggest a solution.

Thanks,
