Descrizione

Contains PDF course guide, as well as a lab environment where students can work through demonstrations and exercises at their own pace. In this course, students will develop the skills necessary to administer one or more Informix database servers. They will learn how to configure and utilize 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 (DS) utilization. If you are enrolling in a Self Paced Virtual Classroom or Web Based Training course, before you enroll, please review the Self-Paced Virtual Classes and Web-Based Training Classes on our Terms and Conditions page, as well as the system requirements, to ensure that your system meets the minimum requirements for this course.
