Environment

• EDR: All Supported Versions

Cause

• Partial installation of JVM needs to update /etc/cb/cb.conf file to point to appropriate directory.

Resolution

• Confirm which directory the /etc/cb/cb.conf file is looking for:

  • cat /etc/cb/cb.conf | grep CbJavaHome

• Check to see which directories exist:

  • ls /usr/lib/jvm

• Update /etc/cb/cb.conf file CbJavaHome parameter to the appropriate JVM directory.  In this instance the /usr/lib/jvm/jre-11/ directory exists but the /usr/lib/jvm/jre-1.8.0/ directory did not:

  • CbJavaHome=/usr/lib/jvm/jre-11/

    
     
• Re-run /usr/share/cb/cbupgrade
