Java is installed into (default paths shown):

• PC: /opt/CA/jre/bin
• DA: /opt/IMDataAggregator/jre/bin
• DC: /opt/IMDataCollector/jre/bin
• DR: As of 21.2.2 there is a difference.
  • Prior to 21.2.2 the DR installer installed the Java JRE to /opt/CA/IMDataRepository_vertica<version>/jre/bin
  • As of 21.2.2 the DR installer no longer installs a persistent Java JRE.

To check the version cd into each of the above directories and run this command.

./java -version

NOTES:

• The ./java command run from within the specified directory is important.
  • If run from another directory with ./ it will fail with a "No such file or directory" message.
  • If run from the correct directory, or any other directory, but without the ./ preceding the java command, it will return the OS systems installed Java version.
    • It does this using the systems PATH variable to find the java command called.
    • Normally this is an older Oracle Java version installed with the OS by default.
• The system Java is not used by any Performance Management component
