How to jump to an explicit server node

Hi,

I have following poblem.

We have an portal environment with 4 physical servers; these server are balanced by a pice of hardware. I can call every of these portal servers by their virtual IP.

On each of these portal servers we have a J2EE installation with 4 J2EE server nodes and excactly here is the problem! We sometimes have issues that are occur only on one server node and pretty often I am not able to reproduce the issue on my client because I am on a different server node like the user.

Is there a possibility how to jump to an explicit server node?

Thank you

Philipp

Hi Philipp,

Patrick already pointed into the right direction, as long as you are still on 7.0 and not already on 7.3.

Nevertheless, the KBA has a small flaw:

It must read

http://<server>:<port>/irj/portal;saplb_*=<NodeID>

and not

http://<server>:<port>/irj/portal;saplb*=<NodeID>

(as written in the KBA).

Of course, the URL can be any portal URL, so you can jump directly to the target page.

There is also one problem where this logic described in the KBA does NOT work: If you have other cookies which are sent initially to the server. This might happen for example if you have some third party analytics software installed on the portal. In this case, the rude method would be deleting all cookies in the browser, the better method would be just to delete the cookies which are interferring (FireFox offers to delete selected cookies) or on IE, use HttpWatch, record one destination call and after that, under tools, "clear recorded cookies".

Hope it helps & best regards to everyone over there

Hi Detlev,

I just read your post: '...as long as you are still on 7.0 and not already on 7.3'

Well I am on 7.3. Is there a simliar possibility you know of to jump to a specific server node? I tried the one from the KBA but it doesn't seem to work.

Thanks in advance.

Dear nik,

As mentioned in the KBA 1589567, for SAP Netweaver 7.1 and higher versions, check SAP NOTE: 1440724.

Does this work in 7.30SP8? We adjusted the specific profile parameter but appending ?sap-nodeid=NODEID seems to have no effect at all.. Judging by the saplb_* cookie received along the line I still get distributed randomly accross the servernodes...

Well I did not get it to work reliably either on 7.30 and higher.

Dear nik,

    I have a system that has about 50 different nodes spread across 7 production portal servers. Nodes act up from time to time. I have also found that if the server node is not acting right, the load balanced link provided above saplb* .... will send you to another node if specified node is down. So you have to check what node you're on.

Regardless, what has worked better than that, is turning up the logging for that node and reviewing the default trace. If this is just a one off situation, which occurs occasionally on different nodes, then usually there is something in the defaultTrace to point to the problem.

Tom

Hi Philipp

Refer to KBA [1589567|https://service.sap.com/sap/support/notes/1589567] - How to login to a specific J2EE engine server node

You should find it helpful. If so, you can rate the document using the stars at the top right corner of the document

Hi,

I think if we are using telnet to login and administer the server then there is specific 'jump' command to directly go to the specific server node.

Can check below links:
