I had 2 questions regarding tomcat configuration:
1) We are currently trying to reconfigure our IIS to point to the tomcats as
follows:
We will have 4 web servers. And 3 app servers each running 4 tomcat instance
each configured to only have AJP connectors. In total 12 tomcat instance
running in total.
And each web server is going to point to all the 12 tomcats for failover at the
web server layer. Is there any downside to such a configuration? Earlier we had
one web server point to only one app server running 4 instances.
2) In the
<!-- Define a Coyote/JK2 AJP 1.3 Connector on port 8009 -->
<Connector port="8009"
enableLookups="false" redirectPort="8443" debug="0"
protocol="AJP/1.3" />
I can define one more attribute named maxProcessors.
A maxProcessors value of zero (0) signifies that the number of
processors is unlimited. If not specified, this atttribute defaults to 20.
In the documentation it mentions for the [maxProcessors] "This should be
set to a value that is greater than or equal to the maximum number of
concurrent connections the remote web server can open to Tomcat
simultaneously."
In the configuration described above(1), since all the webservers are going to
point to all the tomcat instances, we are thinking of putting [maxProcessors
value of zero (0) ] in the AJP connector. Is there any disadvantage to that?
Thanks,
