How do you find the JRE that DB2 uses. I know that db2profile gives the classpath. I thought by default DB2 uses its jre and the dbm cfg parameter "Java Development Kit 1.1 installation path (JDK11_PATH) = "
if set overrides DB2's default path. If I am right, why is the parameter called JDK11...
My only experience with JRE is with DB2 version 8 on Linux. DB2 version 8 automatically installs JRE version 1.3 and sets the path when DB2 is installed. I subsequently installed IBM Java 1.4 and I used the following command to update the path:
db2 update dbm cfg using JDK_PATH /opt/IBMJava2-14
The JRE is necessary to use the GUI tools which are written in Java.
