Category: PostgreSQL
The course is intended for Linux system administrators who will be responsible for the installation, configuration and maintenance of the PostgreSQL database. The training programme covers all elements necessary for the effective cooperation with programmers team on the project based on PostgreSQL.
We focus on practical issues that system administrator has to face to successfully work as a database administrator. Starting from installation , through the most important configuration parameters, basic efficiency tuning, system security and users management. We will also discuss the tools used to diagnose the most common problems and we will tackle the problem of creating backups.
Our instructors have many years of experience with PostgreSQL, both as administrators and as programmers. One of our trainers is a PostgreSQL contributor and a regular speaker at the world’s largest conference on the topic.
