Symptoms

After invoking DBUA from the target ( 12.1.0.2 Home ) , it does not show the right Oracle Home for Source database

Checking the /etc/oratab file shows that the database to be upgraded is rightly mentioned

For this case :

 

 

Though the TEST11 database is rightly mentioned in the oratab file , the dbua was always picking wrong Oracle Home of “/app/oracle/product/test20/12.1.0.2” .
Also , it was not listing the SID TEST11 to upgrade
