Below is a simple code snippet that will help you to export data to CSV/Excel format using Codeigniter and Oracle. Yes, it is obvious that you must have knowledge regarding Codeigniter and Oracle before you proceed further reading.
After continuous google for more than 10 hours, I finally came to a conclusion that the problem “ORA-24408: could not generate unique server group name” was not with oracle instanclient or the connection string oci_connect(). The only problem was with the mis-match of the hostnames of the application server defined in /etc/sysconfig/network & /etc/hosts.

Today, I came up with a solution for how to make an inbuilt Admin Panel with already coded Login module in codeigniter. Just follow the steps below to setup into your project.
