SAP Web AS Connection: ping error

[Former Member]

Wen I test the "SAP Web AS Connection" for the newly created system "SAP_WebDynpro_XSS", I got following error:

6. The server chrisSAP was pinged successfully.

7. The Web AS ping service http://chrisSAP:50000/sap/bc/ping was not pinged successfully. If the ping service is not activated on the Web AS, you can try to call the ping service manually.

8. An HTTP/S connection to http://chrisSAP:50000/webdynpro/dispatcher/ was not obtained successfully; this might be due to a closed port on the Firewall.

I have no firewall installed and Windows firewall disabled.

I can go into the portal with Administrator user through "http://chrisSAP:50000/irj/portal".

So how can I call the ping service manually or acivate it?

What can be the error?

Hi,

Plz check if the service bc is activated in SICF on the Web As R3 system.If not you may activate the entire trr depending upon your requirements.

The question is answered regarding the Abap-stack system, but not regarding the Java-stack only system. (How to install ping services)

I figured out that it is 100% sure that I must enter the connection parameters for the Java-stack-only system where the portal is installed. Even if the ping-service failed, together with the whole connection test, the ESS is running fine now. (I had another problem with it why it did not run).

That's very confusing for me:

A system connection test fails, but the connection is still working fine!

If someone could explain that to me...

Anyway I am closing this thread now. It seems there is no answer for the second part of the question, I'll try to open it in a new thread.

SICF--->Hierarchy type(enter as service) -Execute>you can find services -

Right click and activate the service.

Thank you very much for your answers.

In mentioning "SICF" I recognized that this is an Abap transaction, so I changed the hostname in the Web AS-properties from my local system "chrisSAP:50000" (netweaver 7.0 portal with Java-stack ony) to the remote system "pssv107:8002" (backend ECC6.0 system, abap based) and the connection test was successful (after activating ping-service there)!

But I got very confused now. Did I do the right thing? Or must I connect to my system and activate the ping service there somehow? If yes, how? I can see all kind of services in Visual Administrator, but could not detect any ping service.

More detailed, what me confuses is following description in document "Employee Self Services", Chapter "Set Up Business Package" (http://help.sap.com/saphelp_erp2004/helpdata/en/5b/76a6d7fd3a4e91bfb422405bf3e04d/frameset.htm)

Quotation:

3. Set up your system landscape. To do this, set up the following systems:

Set up the first system on the Portal J2EE server in which the business package has been implemented and assign the system the alias SAP_WebDynpro_XSS. Maintain the WAS properties for this system. In particular:

- WAS host name: <J2EE Name>:<Port>

- WAS path: /webdynpro/dispatcher/

- WAS protocol: http or https

I understood it in a way that I must enter my own J2EE server and not the backend system, because

a) path "/webdynpro/" exist on my local system. Also the webdynpros for the business package are installed on my local system. WAS=Web Application Server is on my local system.

b) it reads "<J2EE Name>", in opposition to "<ECC Backend Name>" used later on.

c) the first sentence talks about my local system and not the backend, so in the sentence "Maintain the WAS properties for this system" the word "this" refers to my system which is a Portal J2EE server, and not to the ECC6.0 Abap system.

d) there is nothing mentioned about a backend system.

So what is my misunderstanding?

Or did I understand it right? But if yes, so how can I activate Ping service here on my java-stack only system?

Even if I understood it wrong, I just want to know theorhetically if it is possible to activate a ping service on my local system or not.

I searched a lot for other documents describing this step, but I could not find any other one. There were some blogs, but they all just quoted these sentences.

I am a SAP beginner and I jumped right away into the cold water by trying to install a portal and get the business packages running in my very first project, so I would very much appreciate it if someone could clarify this for me. Or help me out with some important documentation/blog links that shed more light on this matter. (set up systems for business packages). I mean a description that is not so theorhetically like "<J2EE Name>:<Port>" and nothing more, but a description with a practical example that may read "remoteHost:1111" instead, and explains "remoteHost is the name for your ECC 6.0 backend server that is entered in file .../etc/hosts (verify it by entering 'ping remoteHost'), and 1111 is the port number that can be obtained by logging in to your remote system and calling transaction... and can be tested by ..."

My question:

(How) can you activate the ping service If the mentioned system is a Java-stack-only system?
