Unable to connect to NWA and Visual administrator

[Former Member]

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

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

Hi,

> Caused by: com.sap.engine.services.rmi_p4.P4IOException: Cannot open connection

> on host: 10.103.23.232 and port: 50104

There is problem with port only. As you can seen in above logs. Check whether this port is blocked by some firewall. Also, check P4 port.

Thanks

Hi Sunny, Sorry to get back to you so late, There were few problems that I had to fix in order to bring up J2ee engine.

SAPSR3DB user was locked and I had to unlock and rest the password. J2ee engine comes up and only problem is I can only use super admin user (SAP*) to connect to the nwa and visual admin.

Do you know if SAP* is using different port ? Or the logon mechanisim is different for SAP*?

If I try to logon to Visual admin using message server, I will get connection error. However If I use the dispatcher I can log in.

Is there a note that you can refer me to which deals with post installtion requirments for JVM and ....?

Regards

Sunny - I can not login with the super admin any more. What can explain this connectivity issue?

J2ee engine comes up and only problem is I can only use super admin user (SAP*) to connect to the nwa and visual admin.

Did you activate SAP* on java side? if yes, then follow the link

When you have fixed your configuration, deactivate the SAP* user again.

a. Start the config tool.

b. Set the property ume.superadmin.activated to false.

c. Restart the AS Java.

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
