Unable to connect to NWA and Visual administrator

HI all - I have Java stack installed i at its own database which coexists with another ABAP stack on same virtual machine.

I am not able to connect to Visual administrator to install the saplicens. connection error is as follow

Unable to connect to hostname:50104.

I have checked the value of p4 using configtool and it is 50104.

I have 2 extra emergency users that I have created to make sure if do not face user errors. Since DNS is not resolving FQHN, I have updates /etc/hosts file in my pc to make sure there are no network issues.

The only error I see is in ms_dev which is indicating saplicense has been expired.

Any idea, how to solve this problem?

DB= Oracle 10.2.0.2

CRM JAVA 7.0 EHP1

CRM ABAP 7.0 EHP1

Instances CJX(Java instance) and CSX (ABAP)

Tnsnames Listener and tnscsx

Your help is appreciated.

Regards

K

    Hi Sunny, Thx for taking a look. I think I am in right direction after checking the logs. I did not have a chance to configure UME afterthe install. I am not sure if I should use APAP stack as the source. In the same time, My license is expired and can not connect to NWA or Visual admin.

    Here are the logs

    System trace:

    Please check visual admin log in /usr/sap/<sid>/<instance>/j2ee/admin/log and also paste here.

    Also try to connect to visual admin of this system from any other java stack via remote funcion.

    Thanks

    Sunny
