Checking Usage Types from OS level

There are two ways to check the Usage Types i.e. what all components are installed on the Java engine.
Go to the url http://hostname:port/utl/UsageTypesInfo
If for any reason you are not able to log on to the Java engine then we may also check the same from OS level
Go to path /usr/sap/SID/config, and open the file usagetypes.properties, the first line USAGE= in this file will tell you what all usage types are installed
Example : USAGE=BI-Java\:EPC\:EP
