Linux/Unix

Linux/Unix

While Windows dominates the desktop, Unix is the operating system that dominates most other applications--from spacecraft to supercomputers, from embedded machine controllers to running the World Wide Web. Many profound technical advances in the computer industry (now seen everywhere) originally came from Unix systems--and still do. Linux is a version of Unix that runs on PCs and has become so widespread that it is having a substantial impact on the entire computer industry. This hands-on laboratory course provides an introduction to Linux and Unix. Students gain experience with both the Sun Solaris and Red Hat Linux operating systems--two of the most prevalent versions of Unix on the market today. Topics include history and development of Unix, Solaris and Red Hat GUIs, using the vi editor, the Unix file system, basic Unix commands, and running programs (processes) under Unix. Students should leave the course with a set of basic skills for using any Unix-based system. The material applies to all versions of Unix, including Linux and Apple’s Mac OSX.

Learn how to perform database administration tasks such as creating DB2 instances, creating and populating databases, and using logical design to support concurrency and recovery requirements with DB2 9 for Linux, UNIX, and Windows. New features, such as range partitioning, data row compression, and pureXML (native XML storage) will be introduced. Use a Linux operating system during hands-on labs.

This is an intermediate course for system administrators, database administrators and other technical personnel involved in planning, implementing, and maintaining DB2 for Linux, UNIX and Windows databases.

This program is designed to prepare students for jobs as Linux and UNIX System Administrators. It teaches students to install, configure, protect, and manage Linux and UNIX systems. As a universal operating system, Linux is used in varied production environments such as hosting commercial Web sites, and developing computer-generated feature films. Through the experiences provided by this program, students will acquire the knowledge and skills necessary for employment. They will have opportunities to develop specific skills including: configure mail, print, and network services; manage access of users and groups; write shell scripts; perform backups; and implement intrusion detection and system hardening techniques. These skills can be applied to jobs such as computer operator, system administrator, data recovery planner, Web server administrator, and computer security administrator.
