Performance management requires an understanding of overall system architecture. This course takes the approach of tackling each major system of Linux individually, covering the necessary architectural background and then pointing out how resources are allocated, consumed, released, and reused. Some topics include information about running Linux inside a virtual machine but the focus of this course is Linux as a host operating system, not as a guest. This course will teach you how Linux works so you can determine where bottlenecks and performance problems are.
This course introduces participants to using commands to manipulate files, navigating through the file system, managing processes, writing simple shell scripts and modifying more sophisticated ones, and customizing the environment.
The course provides the students with encouragement to enhance their skills utilizing the techniques presented through classroom problem solving and controlled online workshops. Participants are invited to bring their current ideas and questions to the classroom for discussion. Case studies, lecture, group problem solving, and online laboratories will be used.

This course provides a combination of lecture, discussion and hands-on workshop in several COBOL topics. Write a program to load and read single and multi-dimensional tables. SORT a sequential file in a COBOL program using both Input and Output procedures. Write a program to accept data from the PARM field in JCL and to pass data to a subprogram. Use COBOL Intrinsic Functions such an upper case and Current Date. Write calls to the Language Environment to access system data. Debug common abends including the infamous S0C7, S013, S0C1, S0C4 with Abend Aid and / or LE Dump. Build a series of programs for a “typical” batch job scenario.
This course provides an overview of structured programming concepts. The four divisions of a COBOL program and their functions are reviewed in detail. Participants will gain hands on experience through a series of class discussions and workshop exercises that include several modifications to a skeletal COBOL program. File processing, program looping, conditional program statements, and table processing are covered in detail. Development of clear and understandable program designs is stressed along with building maintainable programs. Program debugging techniques are also discussed.
