The Oracle Database Administrator Guide covers a wide range of topics essential for managing Oracle databases. It includes Oracle basics such as tables, views, indexes, and PL/SQL. Installation and configuration on various operating systems, database creation, and service setup are explored in detail. Key topics like data storage structures, user management, and security ensure administrators can properly manage permissions and prevent unauthorized access. Backup and recovery strategies, performance monitoring, optimization techniques, troubleshooting, high availability, disaster recovery, and database migration are all included for a complete skill set. PL/SQL programming is also part of the curriculum for advanced database handling.

This submission includes useful MATLAB functions for speaker recognition using adapted GMM. The implementation details for steps (i)-(iii) can be found in [1]. The fourth function, gmm2sv.m, connects the means (i.e., centers) of the GMM. The cascade means of the adapted GMM are referred to as the GMM supervector (GSV), which is used in the GMM-SVM based speaker recognition system. More information about the GMM-SVM based speaker recognition system can be found in [2]. These codes require the Netlab toolbox. You can access it at: Netlab Toolbox.
