PO Installation and NWDS

[Former Member]

Dear Experts,

We have a brand new PO Installation. After the installation according to the guide was done we wanted to connect to the CE system from NWDS using "SAP as Java" setting. We installed the latest NWDS from https://nwds.sap.com/swdc/downloads/updates/netweaver/nwds/nw/731/

https://nwds.sap.com/swdc/downloads/updates/netweaver/nwds/nw/731/

Under "SAP as JAva" Settings in NWDS after entrying  the "Instance Host name" and "Instance Number" and clicking ok the popup goes away and there is no entry in the list. Also no error message whatsoever. After i had a look in "Error log" I saw this:

com.sap.managementconsole.datamodel.exceptions.UnauthorizedException: Invalid Response code (401). Server [http://qpmr-nw01.sap:50113/SAPControl] returned message [Unauthorized]. Http proxy info:  none

What are we missing here?

Thanks for the helps.

After having the problem with remote access we have tried to install NWDS directly on CE server.

It is still not working. Here some new findings:

1. After NWDS starts, CE instance is found according to the „Aut. detect local at startup“ setting. But there is a popup for login. The admin user that we are using for CE NWA successfully is not working here. Also the windows admin user/pass. Login popup keeps coming.

2. After hitting cancel several times, we could check SAP as Java settings:

3. Everything looks ok here. But if I try to deploy a process an error message is coming. I guess it happens because of the login failure from step 1.

Hi Koray,

Did I see you mention that you were not the one to do the install?  I'm wondering if they have not completed the Post Installation steps as per the configuration wizard? That question is definitely worth asking as you could all sorts of strange problems if critical parts of the post installation have not been done.

Also I can confirm that the logon  you need to connect from NWDS is definitely a NWA administrator user id - not a windows password.  You need someone with e.g. SAP_BPM_SuperAdmin authority or an equivalent admin role.

Hope that helps.

Regards,

Jocelyn

it was a windows password...

we had a combination of two problems.

Problem 1: "SAP as Java" setting is not working properly if the NWDS is not installed directly on the server. We had to use Sap Management Console perspective to add the instance.

Problem 2: "OS Logon to SAP JEE host" popup appears. Here you have enter a windows administrator for multiple times. once the login works successfully the credentials were saved and never asked again.

For details please refer to this thread:

Interesting! Koray - thanks for cross posting the solution and I'll update my own notes re the password.

Also have you reported these via a SAP Message? If not, I'd encourage you to report the above problems officially via separate SAP Messages - as this helps SAP development to prioritize finding a more permanent solution.

Thanks again.

Hi Jocelyn,

same thing happens if I try with instance number 1.

UnauthorizedException: Invalid Response code (401). Server [http://qpmr-nw01.sap:50113/SAPControl]

Hi Koray... There's usually two adjacent instance numbers associated with the AS Java server. If you think it is meant to be 0, just see if you get a better response by trying instance number 1. I've been caught by this a few times when I was starting oit.

Thanks a lot for the quick responses!

@Jocelyn: Yes we can ping the server. Actually I can access NWA using http://qpmr-nw01.sap:50000

I would get a "The following host name cannot be resolved: xxx" message anyways if there was an access problem on that level.

@Sandip: Hostname: qpmr-nwo1.sap Instance Number: 0. But I have also tried various other things like qpmr1-nwo1 or directly IP address. The main thing bugging me is that I don't get any direct error response. No reaction at all.

What is the deal with http://qpmr-nw01.sap:50113/SAPControl (see error log from above) Is there a setting or a permission that we are missing maybe? I looked around a little bit about the port and saw it is SAP Management Console. Unfortunately I didn't do the installation by myself and have therefore no idea what might be missed there.

Koray

Try running a ping command on your machine from DOS client..

[SandipAgarwalla]

What have you mentioned under Instance Host name" and "Instance Number"

by any chance you mentioned "http" in the instance host name??

Hi Koray

Suggest you check if you can ping the server directly from the NWDS machine.
