Line 10, and then executing jvmtop.sh pointing to a valid process ID.
#Java 11 openjdk amd64 install#
I also tried executing the jvmtop.sh with both. 1 - Install jdk-11 or higher lts version via bash terminal: sudo apt-get install openjdk-11-jdk 2- Find java path via bash terminal: sudo update-alternatives -config java Obs.: It will returns you a path like this: /usr/lib/jvm/java-11-openjdk-amd64/bin/java (copy this path) 3- Edit /.bashrc adding JAVAHOME to it via bash terminal: sudo gedit. I've also verified the folder /usr/lib/jvm/java-11-openjdk-amd64 pointed to by the path actually exists and has contents. I currently have java 11 fully installed and confirmed working (no other java versions, just 11). Update4: I thought my JDE was maybe not installed properly, so I reinstalled Java JDK and JDE. JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64Īs seen in a tutorial I found. The message is still "seems to be no JDK!" (I made sure I logged back in). Update2: I've tried appending the following 3 commands in diferent ocasions, to ~/.profile: export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64/binĮxport JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64/Įxport JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64 usr/lib/jvm/java-11-openjdk-amd64/bin seems to be no JDK! The error still shows up though: echo bash jvmtop.sh -profile 7435 Update1: I made the environment path permanent thanks to instructions from answer.
I got this: /usr/lib/jvm/java-11-openjdk-amd64/bin seems to be no JDK! However, on executing: bash jvmtop.sh -profile I tried to setup JAVA_HOME on ~/.profile's last line: export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64/bin Jvmtop requires JAVA_HOME environment variable to point to a valid JDE. I would also accept alternative Java process profiling options for Ubuntu 20.04 (terminal only) & Java 11, if instructions for installation and execution are clear.
Note: It seems jvmtop is simply broken with Java 11.
