In this course, you will develop the skills necessary to successfully administer one or more database servers. You will learn how to configure and initialize a database server instance, configure and test client connectivity, configure and manage memory and disk usage, plan and implement system maintenance tasks, and configure the server for optimal Online Transaction Processing (OLTP) or decision support.
The course is updated for version 11.50 of Informix Dynamic Server, but is suitable for those still running previous versions of IDS. This course is the classroom delivered version of Instructor Led OnLine course 3X811.
Kurz je určen pro:
This is an intermediate course designed for IDS administrators, Database administrators, and Applications developers.
