Tomcat 8.5.5 with Oracle Apex 8.5.5 and Oracle ORDS 3.0.5.124.10.54 - Error While Connecting to Virtual Host - Message " null’s server IP address could not be found."

Hi,


We've got the following configuration :

Installed the following products on 2 Servers ( ptktl-apex and drptl-apex ) :

- apache-tomcat-8.5.5.zip
- ords.3.0.5.124.10.54.zip
- Apex 18.2

To connect to Apex Builder , we can connect from Both Servers :

http://ptktl-apex:7003/ords_NERP/f?p=4550:1:11994796538363:::::

and

http://drptl-apex:7003/ords_NERP/f?p=4550:1:11994796538363:::::


Virtual Host "apex_test" has been configured into F5 , in order to LoadBalance the 2 servers : ptktl-apex and drptl-apex on Port 7003

while connecting to the following Url :

http://apex_test:7003/ords_NERP/f?p=4550:1:16862187262183:::::

The following Url appears :

http://null/ords_NERP/f?p=4550:1:16862187262183:::::

Error Message :

" This site can’t be reached null’s server IP address could not be found. "


Is there a specific configuration at Tomcat level , to work with Virtual Servers ?

How to implement it ?


Regards,


Harry

We use netscalar to load balance two tomcat apex VMs. We don’t need any
change to tomcat conf for that to work. Just a data point for your
reference.
