Hi all,


I am quite a jboss newbie, dealing with a commercial website made of :

1 f5 load balancer
2 apache with mod_jk 1.2.26 ( with load balancer set as busyness )
4 application servers ( all of them lbfactor of 1 ) 12gb ram, 8cpu, java 1.6.0.11 and jboss-eap-4.3.0.GA_CP06 ( -Xms6144m -Xmx6144m -XX:MaxPermSize=1024m )
2 oracle boxes set up with RAC by dba on the backend


They are running fine and the website is looking good. Course sometimes they swap but nothing to worry about.

I have been told that in a couple of weeks we are gonna have an increment in the accesses on the website.

I do have cacti to monitor apaches and jboss servers ( httpd threads, processes, memory, cpu, load, network et similia ).

Apache is just fine, I cannot see any bottleneck in it at the time being. What I am concerned about is the app servers. By having a look at cpu, load, memory, network they look fine, but what I need to find out in time is whether or not they will be coping with the growing traffic.


Is there anything particular I should be looking at ? I need to make some assumptions before we get the increase of traffic, just to be safe.




Thanks in advance.
