Virtual Host Map has a mixture of HTTP and HTTPS Protocol origin servers

Major goofup on one of my portal servers, suddenly started seeing the following while restarting webcache and webcacheadmin. Protocol of Origin Servers were changed.


13001 Virtual Host Map has a mixture of HTTP and HTTPS Protocol origin servers. All origin servers for a virtual host map must use the same protocol.


This is caused due to virtual host map consists of origin servers with HTTP and HTTPS protocols. A virtual host mapping must consist of origin servers that use either the HTTP protocol exclusively or the HTTPS protocol exclusively.

To resolve this go to Origin Servers definitions page of OracleAS Web Cache Manager, correct the mapping.

1. If you do not have access to Webcache Administrator or if its down, open webcache.xml under ORACLE_HOME/webcache/.
2. Search for Origin Servers definition by searching for the hostname of one of your origin servers. Make sure SSLENABLED="NONE" if your protocol is HTTP for all your Origin Servers.
3. Once this is done restart OracleAS Web Cache and you are good to go.
