To view the discussion, visit: http://community.jboss.org/message/590429#590429 -------------------------------------------------------------- ahh!!! finally we shooted the star...but!!!! It seems like the AJP almost maintains persistent connections, which reduces the scalability, Enabling APR(Apache Portable Runtime) with AJP improves its performance as this polls and closes the sockets, uses adv I/O, shared memory and moreover it is native processing. The channel HTTP+AJP also can be considered. https://owa-emea1.infor.com/owa/redir.aspx?C=f0d08942cd974ad5a8506f89c0ae... http://docs.jboss.org/jbossweb/latest/apr.html After we enabling APR+AJP, the issue is not seen on the jvisualvm cpu time, but then the cpu still hits to 100% and now showing on Oracle parsing. Note*:There could be bugs around these connectors, try using the latest ones. BUT, now the cpu utilization has shifted to oracle oci driver classes, any body has seen this already?? if there are any bugs or etc.., we are using Oracle OCI 11.2.0.1 at the JBoss application server side... http://community.jboss.org/servlet/JiveServlet/downloadImage/2-590429-118...
