sap/xi/engine?type=entry what are other parameters

[vinaymittal]

Hello,

Please tell me where can i find the list of parameters for this Engine Service( you can see this engine service in SICF where to see the code)

I am able to connect to ECC system via SOAP receiver using this url via http

i am also able to connect to ECC via https by https://sapq2029.XXX.YYY:443/sap/xi/engine?type=entry 

but i have to use load balancer which is q97web

http://Q97web.XXX.YYY:443/sap/xi/engine?type=entry  works

but https://Q97web.XXX.YYY:443/sap/xi/engine?type=entry  doesnt work can you help me knowing why...?

Things i found

1) The type H RFC Destination Q97_PROXYSERVER is not enabled for Https

2) The Engine service in SICF is not enabled for SSL

3)The java system property for XPIAdapter:xi .isconfigurl is configured for "http" in NWA

also

i am able to access Abap webservices configured in SOAMANAGER of ECC Q97 by WS Receiver adapter by https://q93web.XXX.YYY/sap/bc/srtetc

i think that the Engine service not enabled for SSL might be a reason.

Please help.

Regards

Vinay

Hi Vinay,

so if i understand you correctly you would like to see both URLs work, right? :

http://Q97web.XXX.YYY:443/sap/xi/engine?type=entry

https://Q97web.XXX.YYY:443/sap/xi/engine?type=entry

i can see you changed from http to https, but what about the port number? You are using 443 in both cases. I think in the second case you should use the HTTPS port number.

Best Regards,

In SE16 of Q97 i checked the table HTTPURLLOC for HTTPS we have port 443 for Q97web so it is fine and also i am able to access SOAMANAGER services via Q93web,XXX.YY on port 443 via https.

I checked it again HTTP has port 80 for this load balancer url and for https it is 443

Hi Vinay,

could you please try to bypass the web dispatcher and to call the IS url directly on HTTPS?

If it turns out that this is working that way, than this will be a web dispatcher problem.

I will do that but can you please tell me the difference between web dispatcher and load balancer

in my system we have Load balancer

                                                                              {-------sapq1029.YYY.XX(http)

                                             sapQ97.YYY.XX---------

                                                                              {-------sapq2029.YYY.XX(https)

and web dispatcher is q97web.YYY.XX is web dispatcher is sort of load balancer?

when to use web dispatcher i use load balancer in RFC sender/Receiver or WS Receiver/sender Adapters and also web dispatcher and load balancer works with soap(XI protocol) so whats the diff between the two.

Above is the sxmb_adm runtime parameter list so what should i check in IS_URL

Hi Vinay,

well, i am not an expert in this question either.

But it is for sure that the SAP Webdispatcher handles the HTTP communication and also in the same time it is dealing with load balancing too (and also doing some other tasks as well):

Hi Vinay,

just try to call the below URL instead of the webdisp url:

https://<host name of the server>:<https port of the server>/sap/xi/engine?type=entry

to see if it is working in a browser or not.

https://sapq2029.YYY.XX:4305/sap/xi/engine?type=entry works

but i need to use the web dispatcher

[former_member204100 · Accepted solution]

great, good to see that this is not a XI service issue, but a web dispatcher one..

In this case maybe raise a question in this group:

SAP NetWeaver Technology Platform

Hopefully somebody can figure it out how to configure the WDP in this group.
