Hi Spacewalk masters,

I'm trying to make things work between Spacewalk and Pgpool-II to get a 
Spacewalk HA.
I've already configured a cluster with two nodes of Postgresql in v. 10.2. To 
manage these cluster, I've another setup with pgpool-II version 3.6.7 
(subaruboshi) all in Oracle Linux 6.

When Spacewalk is installed in a new server (with Oracle Linux 7) (following 
the instructions of this page: 
https://github.com/spacewalkproject/spacewalk/wiki/HowToInstall), never 
complete the installation and shows an error like "Tomcat failed to start 
properly or the installer ran out of tries"

Looking on catalina.out I can find:

INFO: Illegal access: this web application instance has been stopped already.  
Could not load java.util.Enumeration.  The eventual following stack trace is 
caused by an error thrown for debugging purposes as well as to attempt to 
terminate the thread which caused the illegal access, and has no functional 
impact.
java.lang.IllegalStateException

But when I try to access, Spacewalk shows a blank page.
Did someone try to do this before? Any idea of how can I find in some file the 
information of spacewalk when it tries to connect to an external database to 
find a possible solution?

Thanks for your help
