Netweaver 7.3 with Apache as reverse proxy

[Former Member]

Hi

I am facing an issue. I am not able to find the solution anywhere... Do let me know if u solved it

I am trying to reverse proxy SAP 7.3 using Apache 2.0.6.4 as the webserver. It was working fine with SAP 7.01. But with 7.3, i am facing GUI problems, the URL says i have been logged in, but the GUI is not being displayed....

"The requested URL /com.sap.portal.pagebuilder/html/EmptyDocument.html was not found on this server."

^^ is the error message that i am getting.

Below is the reverse proxy lines that i have added in the httpd.conf file of apache. which worked fine for SAP 7.01

ProxyRequests Off

ProxyPass /irj http://<SAP 7.3 IP>:50000/irj/

ProxyPassReverse /irj http://<SAP 7.3 IP>:50000/irj/

ProxyPreserveHost On

ProxyRequests Off

ProxyPass /webdynpro http://<SAP 7.3 IP>:50000/webdynpro

ProxyPassReverse /webdynpro http://<SAP 7.3 IP>/webdynpro

ProxyPreserveHost On

We are also getting this error after potal 7.3 upgrade. Has this been answered?  I am not able to find the solution anywhere yet.

Thanks

With NW73 you need to proxy all requests, not just /irj. See the attached discussion thread for details.

Hi Samuli,

Thanks a lot for the help. It is resolved now.

Proxied all the requests.

ProxyRequests Off

ProxyPass / http://<SAP 7.3 IP>:50000/

ProxyPassReverse / http://<SAP 7.3 IP>:50000/

ProxyPreserveHost On

What is the location of time out parameter.

Hi Samrat,

1).Go to RZ10

2).Select Instance Profile

3).Check the Extended Maintenance Radio Button

4).Click on Change Button.

5).Check for rdisp/j2ee_timeout

There you can increase the time

Set profile rdisp/gui_auto_logout to how many second you require.

Hope this will be helpful.

Configure the ReWriteLog and you should see the errors:

ReWriteLogLevel 1

ReWriteLog /var/log/apache2/rewrite_http.log

/M

I'm just guessing here but I think your rule is wrong, you can't include the trailing slash in the target if the source doesn't have it. Try this configuration:

ProxyRequests Off

ProxyPass /irj http://<SAP 7.3 IP>:50000/irj

ProxyPassReverse /irj http://<SAP 7.3 IP>:50000/irj

ProxyPreserveHost On

See the attached document for further tips on how to configure Apache as a reverse proxy.

This line misses the port number (though i suspect it is correct in your config):

ProxyPassReverse /webdynpro http://<SAP 7.3 IP>/webdynpro

I suggest you use a tool like httpwatch to check your browsers requests.
