Subject No direct access to Tomcat as it is using AJP connector?
Date Tue, 10 Nov 2015 10:18:09 GMT
Hi All,

I have the following configuration.

Standalone Apache web server is talking to Tomcat AS using AJP connector.
Both Apache and Tomcat are running on seperate server machines. All my
application components are deployed on the Tomcat AS and Apache is just
used to redirect the user requests to Tomcat.

Now I have the following requirement, I have been asked by my operation
team member that he needs to " replace Battery and install McAfee" on the
Apache web server and the activity would require approx. 1 hour. He also
told me that during this period of time, the entire application would not
be accessible!

My question to him was that why can't users access the application by
directly putting the IP of the Tomcat server in the browser during the time
Apache web server is under maintenance? Why can't we access the Tomcat AS
directly? Once the Apache is up, users can then use the actual URL and
access the application again via Apache web server.

But the short answer I got from the team member was that *there is no
alternate URL as Tomcat is using AJP connector which cannot be accessed via
browser. *

So my question is if it really true and there is no alternate way (quick
solution/workaround) we can avoid the complete outage of the application?

I am not technically aware of this AJP configuration and constraint, so
that's why I want to make sure if the above condition stated by the team
member is indeed correct. May be he lacks or unaware of any other alternate.

So any help/clarification would be really appreciated.

Many thanks.

Regards Suleman
