Solution:

While upgrading to Zephyr Enterprise 7.18.0 version, if you are using any monitoring tool integrated with Zephyr, you need to remove the settings.

You must follow the steps below:

For Linux

  1. In the ZE, navigate to setenv.sh in the {ZephyrDir}/tomcat/bin folder.

  2. Open the setenv.sh file in any editor and confirm if the below line is present in the file.
    Delete lines other than these lines present in the file.

    export JAVA_HOME=/usr/java/jdk1.8.0_151
export CATALINA_PID=/home/zephyr/zephyr/bin/zephyr.pid
export JAVA_OPTS="-server -Xms2048m -Xmx4096m -XX:MaxMetaspaceSize=512m Dorg.terracotta.quartz.skipUpdateCheck=true -Djava.awt.headless=true"

For Windows

  1. Open the command prompt.

  2. Navigate to the location where Zephyr is installed {ZephyrDir}\tomcat\bin

  3. Type the command-
    tomcat9w.exe //ES//Zephyrserver

  4. The Zephyr Server Properties open.

  5. Navigate to Java option in the Zephyr Server Properties.


  6. In the Java Options, confirm if the below lines are present in the file.
    Delete lines other than these lines present in the file.: 

    -XX:MaxMetaspaceSize=512m
-Dorg.terracotta.quartz.skipUpdateCheck=true
-Dcatalina.home=C:\Program Files\Zephyr\tomcat
-Dcatalina.base=C:\Program Files\Zephyr\tomcat
-Djava.endorsed.dirs=C:\Program Files\Zephyr\tomcat\endorsed
-Djava.io.tmpdir=C:\Program Files\Zephyr\tomcat\temp
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=C:\Program Files\Zephyr\tomcat\conf\logging.properties
