How to connect to NetWeaver running on VM

[Former Member]

Newbie question. I was asked to look at the possibility to pull (import) /push (export) data from SLD to our System Management aap.

After spending hours several hours searching related info I found that

1. SLD is the component of NetWeaver and does not  exists on its own as a standalone server. Is it rue of false?
2. In order to play with SLD one should install, if it does not have, NetWeaver. Is it true?
3. I spent hours and hours tiring to install NW 7.4 on Windows 7 and failed on post-installation step 28 - while starting Java engine. Maybe it is because my system does not meet prerequisites (NW requires Windows server not workstation) maybe because of something else. Can NW 7.4 be installed and run on Win7 ? (I am not talking about production environment).
4. So, I ordered Linux VM with NW731 preinstalled. How can I connect to NW from browser or SAP GUI client running on Windows (preferable)?

On VM where NW731 installed I see:

NW371DUAL:/usr/sap # ls

DAA    N7J    N73  ....

NW731DUAL:/usr/sap # ls N7J

J02   SCS03  SYS

I would guess that Instance number is 03 and System ID is SCS. These two fields required on connection tab SAP Logon 730 dialog.

Can't connect. Am I doing something wrong?

What http port should be used if I want to connect from browser?

Thank you in advance.

After several days battle with connection by trying all possible options, (thank community for the help) I gave up and canceled  NW731 dual stack VM loan  due to lack of information provided by MyLab.

Anyway I ordered NW74 for ABAP, even I need Java stack, but I could not find NW74 for Java.  This time email came with information how to connect to NW – user name, password, SID, instance number…

However it did not come without surprises either. Attempt to connect from SAP GUI failed with error: “Logon not possible (error in license check)”.

This is from email:

IMPORTANT: you need to install a Temporary License Key after your delivered request.
, Please Refer to our Wiki to install new one
To extend the License of the System : https://isp.wdf.sap.corp/sap/bc/bsp/sap/zkey_webas/start.htm
you'll need the Hardware Key of your System to obtain your new license, you can find it in the Transaction SLICENSE in the client 000 ( Connect with sap*/Welcome1 )
For further details, go to our Wiki : https://wiki.wdf.sap.corp/wiki/display/HanaVM/NW+7.40+ABAP+on+HANA

There is no need to say that the above link where I could find further details is broken. However by tweaking the URL I was able to get into wiki, but could not find the information how to install the temporary license.  Even more,  at the bottom of the message:

A temporary license is automatically installed. This license is valid for 90 days. After 90 days, the license expires and the system is locked down (for more information, see the Wiki....

Obvious that this sentence contradicts to sentence above which says “you have to install a Temp License”.

And here are the questions:  why connection is failing? Is license installed and if it is not how to install it?

Thank you,

Hello IIya

Have you the JCMON/JSMON tools like I suggested above.

There is an option to list the ports used by the Java stack.

The J2EE processes should be running.

You can also check the trace files in the /usr/sap/SID/Jxx/work directory.

Check the trace files dev_server, std_server, dev_dispatcher and std_dispatcher.

I did, but both tools respond on any command I entered: Can't open shared memory administration (rc = 3)

[Reagan]

In that case the Java system is not running.

Please check the trace files in the work directory.

Hi Reagan,

It is running based on what I see in 'ps wuax | grep NW' output and looking at dev_server0

Hi llya,

You need to connect with the below url

http://<hostname>:50200

Thanks Ashutosh. I tried http://10.48.152.71:50200 with no success (same as

http://NW731dual.dhcp.pal.sap.corp:50200)

Hi llya,

1. What error are you getting?

2. Are you trying to access the page from a remote desktop or from the server itself.

Hi Ashutosh,

The error I am getting: "Chrome could not connect to 10.48.152.71.50200"

I am connecting from remote Windows desktop.

Thanks,

Hi llya,

check the below points

1. Ping the ip 10.48.152.71 from the remote desktop

2. If it is getting ping then telnet it from remote desktop

   telnet 10.48.152.71 50200

3. if above is working then , then mainatain the host entry in hosts file

   <ip> <FQDN> <hostname

Hi Ashutosh,

ping certainly succedded,

telnet failed with error Connecting To 10.48.152.71... Could not open connection to the host, on port  50200: Connect failed.

I believe the N7J is the one you want to access and is a Java stack, If yes then check whether the Java stack is up and running.

The system number is 02.

http://NW731dual.dhcp.pal.sap.corp:50200/nwa

If there is an ABAP stack then you can use SAP GUI to access it.

Thanks Reagan. Same failure.

BTW when I tried to connect from SAP GUI I was using either 'SCS 03' or 'N7J 02' with no success.

Please check whether the SAP system is up and running.

You can use jsmon / jcmon to check whether the processes are running at the OS level.

Hi llya,

Now you have to check whether the sap is up or not.

IF sap is up,

Then

You need to check the port 50200 is open or not.

You need to involve the firewall or network team to open the port 50200. Once it done , then try to connect.

Hi Ashutosh,

Why should I do all that? I am within firewall on sap intranet same as NW731DUAL.dhcp.pal.sap.corp?

[former_member185239]

Hi llya,

Can you check the below url

http://10.48.152.71.50213

You need to check it because , it may happen that 50200 port is not accessible from outside even it is in same domain.

Hi Reagan,

I logged in on NW731DUAL.dhcp.pal.sap.corp and checked NW processes. NW is running. Then I run netstat -lpn and  looked what port NW processes listen. I found that NW listens port 50213.

When I connected to http://NW731DUAL.dhcp.pal.sap.corp:50213 SAP Management Console popped up with message connection failed (see attachments)

Additional error message is showen on Operation System tab:

The SAPHostAgent seems not to be installed or Running on NW731.dhcp.pal.sap.corp.

Please install SAPHostAgent as described by Note 1031096 or if already installed, just start it.

Browser window http://nw731dual.dhcp.pal.sap.corp:50213/sapmc/sapmc.html?SID=N7J&NR=02&HOST=NW731DUAL.dhcp.pal.sap....  shows two disabled buttons.

Any ideas?
