If you are using Java 1.6 or earlier as the default JVM, you must unset environment variable JRE_HOME, if you do not the OpsConsole may not start.
If it exists in your environment, unset JRE_HOME. RAP uses Java 1.6, which is automatically installed.
Note:
The environment variable $JRE_HOME should point to $RAP/shared/jre16.
