Reports 12c Example:

1. Set your environment by using sourcing reports.sh:
     cd $DOMAIN_HOME/reports/bin
     . ./reports.sh

2. Try to connect using sqlplus:
     cd $ORACLE_HOME/bin
     ./sqlplus user/password@db

           (where user/password@db is the same connect string used in your call to Reports)

3. If it works, then your connect string is okay. Please proceed to Actions section below for further troubleshooting.
