Subject Re: [users@httpd] Issues migrating Weblogic proxies from Sun One 6.1 to Apache 2.4
Date Fri, 01 Jul 2016 00:32:13 GMT
Hello Joe,

First of all, beginning with version 12.2.1, OHS is based on Apache 
httpd 2.4.x.
But the Apache httpd form of the WLS plug-in should also be working for you.

I can try to help you in working with the Oracle support people.
Could you send directly to my email (to keep your information private) 
the name of the person in Oracle support that you are working with and 
the SR number they have assigned to you?
I will see if I can check on the status for you.

In the meantime, perhaps Rainer or someone else on this mailing list 
will have further ideas from the Apache httpd point of view.

closed the port, the Weblogic application server tried to send data.  It almost like Weblogic
did not realize the port was closed.  Very odd.

it is based on Apache 2.2, and I was hoping to take advantage of the improved performance
offered by Apache 2.4.  Also reading through the documentation it looks like a PITA to install
(we have to install X to the run "Oracle Universal Installer" ?  Seriously ?)  Maybe Oracle
support will take us more seriously and give us better support if we are using all their products.

we would have just purchased Oracle HTTP Server.  At least we would have full Oracle support
through and through, although that may not be saying much, since it is based on Apache 2.2.
    Also I am worried about Oracle compatibility with 3rd party plug-ins like RSA Access Manager
(SSO) and Tea Leaf.
