Hi All,

The Oracle utility DMU 2.2 (Database Migration Assistant for Unicode) is not working on my RHEL 7 machine. It is throwing java errors.

java -version

openjdk version "1.8.0_171"

OpenJDK Runtime Environment (build 1.8.0_171-b10)

OpenJDK 64-Bit Server VM (build 25.171-b10, mixed mode)

The server version is: uname -a

Linux servername 3.10.0-862.6.3.el7.x86_64 #1 SMP Fri Jun 15 17:57:37 EDT 2018 x86_64 x86_64 x86_64 GNU/Linux

The steps I have followed:

export JAVA_HOME=/usr/java/jdk1.8.0_181-amd64

export OIDE_JAVA_HOME=/usr/java/jdk1.8.0_181-amd64

mkdir -p $ORACLE_HOME/dmu-2.2/dmu

cd $ORACLE_HOME/dmu-2.2/dmu

unzip dmu-2.2.zip

chmod 755 dmu.sh

./dmu.sh

I have also uninstalled any other versions of java from output of: alternatives --config java

Howdy, Stranger!
