How to configure Web Dispatcher to use 3rd party's recommended health check URL?

Hi Experts,

I have an SAP Web Dispatcher which I'm using to load balance requests going into a 3rd party (non-SAP) system. The 3rd party system guide says I can "configure URL http://<server address>/SXP/IsAlive.aspx in the load balancer in order to monitor the health of the 3rd party application server".

How would I go about configuring this in the SAP Web Dispatcher?

my URL with the healthcheck is: "http://<server address>/SXP/IsAlive.aspx"

Is there a parameter to which I would add this URL?

Appreciate your help - this is very urgent!!! Will award points to the correct answer.

Best regards,

Esteban

    Hello Esteban,

    Set the parameter "wdisp/ping_extsrv_url = /SXP/IsAlive.aspx".

    Refer to this SAP Help page.

    • Hello Esteban,

      Please set the parameter "rdisp/TRACE = 2" at the Web Dispatcher profile and restart it.

      Then, wait for about 1 minute and simulate the issue.

      Stop the Web Dispatcher and save a copy of:

      1. The profile used during the testing;
      2. The "dev_webdisp" and "dev_webdisp.old" trace files.

      You can then remove the parameter "rdisp/TRACE" and start the Web Dispatcher again.

      Compress ("zip") the files from item #1 and #2 and update this question, attaching the compressed file.

      We can then analyze the trace to see what is happening.

      Best regards,
