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 Actionssection below for further troubleshooting.

4. If it fails, then it is not an Oracle Reports issue.  The connection must work with SQL*Plus before it can work with Oracle Reports.
