HP OpenVMS Crash Dump Analysis for Integrity Servers

Course Code: U3723S
Length: 5 days

Schedule and Registration

This course is not currently scheduled.

Course Description

This course provides the foundations to perform crash dump analysis on HP OpenVMS Integrity servers. Itanium architectural characteristics are introduced in order to analyze crash dumps and system hangs. The calling standard is reviewed, allowing students to walk call frames to determine where improper arguments to a function call have been passed. Interrupts and exceptions are discussed, as well as their handling by the Software Interrupt Services (SWIS). Considerable time is spent exploring different types of crashes and reviewing specific examples.

Who Should Attend

hp OpenVMS System Programmers and Advanced Troubleshooters, especially those who understand the coding considerations for code that will run in kernel or executive mode.


To get the most out of this course, students should have:
