Hi all,

We have two node rac  with   12.1.0.2 database and 19c GI (recently upgraded) on REHL 7.6 64 bit .

We are planning to upgrade the database to 19c . 

While running the preupgrade tool getting the following error. Any thoughts?

I have installed the 19.3 binaries in new 19.3.0 home

export  ORACLE_SID=TEST

export ORACLE_BASE=/oracle/app/oracle

export ORACLE_HOME=/oracle/app/oracle/product/12.1.0.2/dbhome_1

/oracle/app/oracle/product/12.1.0.2/dbhome_1/jdk/bin/java –jar /oracle/app/oracle/product/19.3.0/dbhome_1/rdbms/admin/preupgrade.jar TERMINAL TEXT

Exception in thread "main" java.lang.NoClassDefFoundError: –jar

Caused by: java.lang.ClassNotFoundException: –jar

        at java.net.URLClassLoader$1.run(URLClassLoader.java:202)

Howdy, Stranger!
