JDK 1.7 installed. (The JRE is not sufficient to run OMS!)
ANT 1.8+ (Only if you need to build a model from within the Console)
GCC 4.+ (Only if you need to integrate native code in FORTRAN or C)
You need to set the JAVA_HOME environment variable, and let it point to your
JDK install directory. See FAQ on how to so it if you are not sure.
Unzip the distribution into any folder.
Execute console.sh or console.bat in order to execute it.
On its first execution the console will install required jar files and configuration files
into HOME/.oms. Those files are being used to run models, or an IDE can use
those jar files during model development.
