Web Dispatcher configuration for Analytical Apps

[juancarlos_camachogarduo]

Hi everyone!

We are configuring SAP WebDispatcher with SimpleFinance to work with analitycs apps but we have an 503 issue in the Web Dispatcher -checkconfig and when we test the next xsodata through the Web Dispatcher

*testing the hana odata through dispatcher

*WebDispatcher -checkconfig

*Test of the hana service directly, its working fine

*Fiori through Dispatcher works fine too

*The IP of host sap4hana02-tn1.com can be resolved in the web dispatcher server, we do tracert with success...

Our landscape & webdispatcher.pfl;

a. SAP Web Dispatcher is installed on SAP4HANA03 and listening on HTTPs port 44306.

b. SAP Back/Front-end Server is installed on SAP4HANA02.

c. The public url for the SAP HANA tenant database is http://vmesap4hana02-tn1.com:8000,we apply the settings for the XS Engine & HTTP (S) Access to multitenant database containers, the XS Engine of the SYSTEMDB and the TN1 works fine.

wdisp/system_0 = SID=PW2, NR=00, MSHOST=sap4hana02.com, MSPORT=8102, SRCSRV=*:*, SRCURL=/sap/opu/odata, SSL_ENCRYPT=0

wdisp/system_1 = SID=PW2, NR=00, MSHOST=sap4hana02.southcentralus.cloudapp.azure.com, MSPORT=8102, SRCSRV=*:*, SRCURL=/sap/public/bc/;/sap/bc/, SSL_ENCRYPT=0

wdisp/system_2 = SID=TN1, EXTSRV=http://sap4hana02-tn1.com:8000,SRCSRV=*:*, SRCURL=/sap/hba/;/sap/hana/

Any suggestions?,

Hi Juan,

Try following parameters in your WD profile, restart, and retest:

wdisp/ssl_encrypt = 0

icm/accept_forwarded_cert_via_http = true

Also, Refer to SAP Web Dispatcher for Fiori guide: http://scn.sap.com/docs/DOC-62723

Regards,

Kiran

Hi Kiran!

Thanks for your suggestion, I added the parameters, restart and retest but still have the same issue.

Here our webdispatcher.pfl;

Now, we are trying to understand this with these notes;

2209246 - SAP Web Dispatcher for Multitenant Database Containers

2088121 - Web Dispatcher - Access to /sap/hana/xs/internal/topology.xscfunc is denied
