There are 2 file types use the .ORA file extension:
1. Oracle Database Configuration File
Text file used by Oracle Database, an enterprise-level relational database management system (RDBMS); contains database configuration parameters; used for storing system-wide defaults and for fine-tuning database performance.
All parameters in ORA files are optional since the Oracle database already contains default values for the required parameters. Parameters can be specified in any order.
Common ORA filenames include init.ora (initialization parameters) and tnsnames.ora (SQL*Net connection configuration file).

2. OpenRaster Image File
