The OT is a Java application that will work on any compatible JavaVirtual Machine (JVM) installed on yourplatform. The JVM, if correctly installed, executes the OT platformindependent binary code. The JVM is part of the so-called Java RuntimeEnvironment (JRE) , which is thesoftware environment in which programmes compiled for a JVMimplementation can run (see Appendix B.1 ).
Because of its Java dependency, installing and running the ALMA OTrequires the Java Runtime Environment, JRE 6.0 (which contains JVM1.6). Most likely, Java is already installed on your computer. Theversion of your Java installation can be checked from the UNIX and DOSCommand Line using the command java -version . The command willprint a string like java version 1.6.0_05 . If the Java versionis earlier than version 1.6, you should get the latest version of JREfrom the Java download page:
The page contains downloads for the various platforms and instructionsfor the OT installation and deployment. One can also download the JREsoftware using the DOWNLOAD link that actually detects theplatform in use. If you run into problems with the installation youcan ask your computing support to install it for you. It is possibleto install the JRE in your own directory space.
Below, in Sections 2.2 and 2.3 , the details ofthe installation of the OT using Web Start and the tarball installationare discussed. Independent of the installation method used, the OTwill be installed with a default configuration suitable for thegeneral user. Details of the OT configuration are provided inAppendix A .
