OpenVMS Performance Management
This course presents OpenVMS performance under three subsystems: Memory Management, I/O, and CPU. This course features:
-
Isolating performance bottlenecks to one of the three subsystems.
-
Effects of SYSGEN parameters on each of the subsystems, when to change these parameters, and when other management modifications or the purchase of new hardware will be required.
-
Sufficiency (keeping the system running), as well as tuning considerations.
-
The relative merits/drawbacks of using AUTOGEN
Benefits of Attending this Class :
Upon completion of this course, students will be able to:
-
interpret performance metrics supplied by the MONITOR utility, the INSTALL utility, and DCL commands such as $ SHOW SYSTEM , $ SHOW STATUS , $ SHOW MEMORY
-
Identify bottlenecks in subsystems Memory Management, I/O and CPU
-
Size working set parameters.
-
Monitor page file space.
-
Describe the advantages of balancing disk I/O.
-
Improve the performance characteristics of indexed files using the CONVERT utility.
-
Identify factors contributing to time spent executing in processor modes.
-
Describe file locking design considerations to attain good performance.
-
Monitor distributed lock traffic and impact its performance.
-
Identify the impact of changing key system parameters.

OpenVMS Internals for System Managers
FEATURING WAYNE SAUER!!!!
This course presents the components, structures and mechanisms of the
OpenVMS Alpha operating system. It is designed for those of you who don't currently have deep background in programming, but who want a better understanding of how OpenVMS works. Topics covered are aimed at providing you with a better understanding of general troubleshooting and performance, based on a fundamental understanding of how OpenVMS works.
The course will provide a general overview of system mechanisms, such as Interrupt Priority Level, Spinlocks, CPU context, access modes, etc. You will be able to use the System Dump Analyzer on a live system to examine the data structures that form the Operating System. The class will explore the dynamics of the Operating System through changes to data structures visible through SDA. Focus will be on the three major subsystems of OpenVMS: Process and Scheduling, Memory Management, and I/O. We'll develop a big picture understanding of the internals of OpenVMS, and then apply these concepts by exploring process hangs in a variety of resource wait states.
