Java Runtime Environment TIBCO Runtime Agent bundles the Java Runtime Environment (JRE). A JRE installer is embedded in the TIBCO Runtime Agent suite installer. TIBCO Runtime Agent requires that the TIBCO installable JRE be installed. TIBCO Java applications will use the JRE installed by TIBCO. You can manually configure environment variables and configuration files to force use of a different JRE. On some operating system platforms, you must download IOracle Java 7 Elliptic Curve Cryptography (ECC) LGPL separately. Oracle ships the SunEC (an ECC implementation) library as part of JRE 7. The SunEC library is covered by a different license (LGPL). Install this library to take advantage of ECC. The TIBCO Universal Installer automatically downloads the library for you from download.tibco.com during installation. If you do not wish to install the Elliptic Curve Cryptography library, you may delete the library named libsunec.so (on Solaris and Linux systems) or sunsec.dll (on Windows systems) or libsunec.dylib (on MacOS) from the TIBCO JRE bin directory reserved for native libraries.
