I could not connect to the Oracle Instance on Amazon RDS platform when I worked in the town library. I followed the following steps and resolved the issue: 1. Find my IP address using Google Search "my ip address". Google will display my ip address 64.64.117.xx. 2. Go to Amazon AWS console/Services/RDS/Dashboard/Instance. Right click the instance and select "See details". 3. From the detail view, click the link to next to "Security Groups". 4. At the bottom section, click Inbound and then Edit 5. Click Add Rule and add the IP address 64.64.117.xx/32.
