Hi Experts,
I am trying to install SAP NW 2004s SR1 with Linux [Red Hat Enterprise Linux AS release 4 (Nahant Update 4)
, Kernel (2.6.9-42.EL)] and Oracle 10.2. I am getting the following error:
=============
SAP NetWeaver
SAPinst Installation GUI
Could not connect to host localhost on port 21212
java.net.ConnectException:Connection refused
Host: localhost
Port 21212
==================
I am using SDK 1.4.2_16.
Kindly help me to resolve go ahead in installation.
Regards.......Yogesh
You might want to check the process list to see if the installer is already running or run 'netstat' to see if a different program is already using that port. This could also be caused by a restrictive firewall or miss-configured settings in the hosts file.
Hope that helps.

Hi,
1. Check entires in /etc/host .... try adding <hostname> to 127.0.0.1
2. Check/set env variable JAVA_HOME

Hi Yogesh,
The error comes if :-
1. Incorrect version of JDK.
2. Java_Home is not set.
3.The port is already as an old binary is using it.
Please check on the above lines.
Thanks
Pankaj
And make sure the firewall is off. you can turn if off by
/etc/init.d/iptables stop
Java 1.4.2_19 is the one you should use as it is supported by SAP.
