Migrating from adnjdk18 to OpenJDK 1.8.0
Perform the next steps to migrate an existing nevisMeta instance running with adnjdk18 to OpenJDK 1.8.0:
- Check whether OpenJDK 1.8.0 JDK (java-1.8.0-openjdk-devel package) is already installed on your operating system:
yum list installed java-1.8.0-openjdk-devel
- Install the package in case it is not available:
yum install java-1.8.0-openjdk-devel
- Set the JAVA_HOME variable in the corresponding configuration file to your deployment type (as documented in Deployment types:
# Glassfish deployment: /var/opt/adnglassfish/<instance name>/conf/env.conf
# Standalone deployment: /var/opt/nevismeta/<instance name>/conf/env.conf
JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk
- Restart the nevisMeta instance:
nevismeta <instance name> stop
nevismeta <instance name> start
