Day 5

• Unit 7 - Recovery termination manager (Continued)

• Explain the MVS functions and control blocks necessary to support a task in a multitasking and multiprocessing environment
• Describe the software and hardware functions that allow a program to interact with programs running in other address spaces, use data in other address spaces, and use data in data spaces
• Trace the flow of an I/O operation from the initial request in the application program through the completion of data transfer
• Identify the control blocks that describe the current status of an I/O request
• Describe the functions of the z/OS BCP Virtual, Real, and Auxiliary Storage Managers
• Describe the functions performed by the Recovery Termination Manager and recovery management components to minimize failure impact and enhance error correction
• Select the appropriate IBM publication to provide further technical information (SRLs, Technical Bulletins, Self-study and other z/OS courses)
• Describe the services provided by cross system extended services (XES)
• Identify and explain the purpose of the cache, list, and lock structures
• Plan the implementation of the global resource serialization STAR environment.0.2 pref

presentation, discussion, hands-on exercises

This course presents the structure and control blocks of the z/OS BCP and system services. It prepares the new z/OS system programmer to identify potential bottlenecks and performance problems, perform initial error symptom gathering, and identify opportunities and requirements for tailoring a z/OS system. This course also provides prerequisite information needed for further training in specialized areas such as system measurement and tuning and system problem determination.

The primary audience for this intermediate course are z/OS system programmers who are new to z/OS installation, customization, measurement and tuning, or problem determination. Subsystem programmers will also benefit from this class.
