Strange error when enabling SSL on Oracle HTTP Server

Question

Hi,
In our production environment Oracle HTTP Server starts fine when SSL is disabled.
We've enabled SSL in our dev/uat environments using instructions from the Oracle Documentation. It was pretty straightforward.
When i tried to do the same in our production environment, the Oracle HTTP Server wouldnt restart. I've had a look around the forums and havent seen anyone report the same error we are seeing in the logfile.
$ORACE_HOME/opmn/bin/opmnctl verbose startproc ias-component=HTTP_Server
HTTP/1.1 200 OK
Content-Length: 0
Content-Type: text/html
Response: Ping succeeded.
opmnctl: starting opmn managed processes...

</msg>
</process>
</process-set>
</process-type>
</ias-component>
</ias-instance>
</opmn>
</response>
The HTTP_Server~1 log contains the below error:
09/08/16 13:24:40 Start process

No Apache logs are being written to when we try starting the Oracle HTTP Server with ssl enabled.
Has anyone experienced this problem before? Any idea how we can get this working?
Thanks,
Stephen

Answer 1

Noticed that when it starts with apachectl startssl, it doesnt like any <VirtualHost directive
The line in the dms.conf file that it errors out at is :
<VirtualHost 127.0.0.1:7201>
When i added a redirect the httpd.conf file, it errors out at the <VirtualHost line also
Any idea why the Oracle HTTP Server wouldnt like <VirtualHost directives when running startssl?
