SCOM 2012 also brings comprehensive support for monitoring Java Enterprise Edition (JEE, formerly known as J2E) application servers. It supports four servers: IBM WebSphere 6.1 and 7; Red Hat JBoss 4.2, 5.1 and 6; Oracle WebLogic 10g Rel3 and 11g Rel1; and the open source Apache Tomcat 5.5, 6 and 7 on both Windows and Linux. It also supports WebSphere on AIX and WebLogic on Solaris.
