T2 Solaris Kernel Performance, Observability, and Debugging (Day 1 of 2) NEW!
James Mauro and Richard McDougall, Sun Microsystems
9:00 a.m.–5:00 p.m.

Who should attend: System and database administrators, software architects, developers and programmers, performance and systems analysts, and IT architects wanting to obtain a deeper understanding of the key Solaris subsystems, as well as the tools and facilities that can be used to:

  • Observe, trace, and debug to optimize performance
  • Observe, trace, and debug to root-cause aberrent behavior
  • Observe and trace to understand how the application workload interacts with the operating system
  • Better understand the system as a whole
Attendees should have some basic understanding of operating system principles and application performance analysis. Students choosing to attend only Day Two should be familiar with Solaris kernel subsystems and have at least rudimentary knowledge of the bundled tools and utilities and their use.

Applications are becoming more complex every day, and many of the new Solaris features significantly reduce the effort required to administer and anazlyze performance of the entire application and operating system stack.

You may take this class as either a one-day experts class or a two-day complete class. On Day One, we provide an architectual overview of the major Solaris subsystems and an introduction to Solaris performance analysis. On Day Two, we cover advanced topics and spend significant time with hands-on case studies, using the latest tools, including dtrace, mdb, memtool, mdb, trapstat and the Solaris process "ptools."

Whether your environment is a single server or a network with thousands of desktops, workstations, and servers, Linux application deployment, upgrades, and errata policy can be effectively managed with RPM packages. From simple command-line queries to source build environments, from networked package management solutions such as Novell's Zenworks for Linux and Red Hat's RHN to the simple but effective Yum, this course emphasizes real-world solutions, covering everything you need to know to use, create, and manage RPM packages and systems.

Topics include:

  • Introduction to RPM: What's a package and what isn't
  • Working with RPMs: Basic functionality explored
  • Advanced RPM use: Auto dependency aid, rollback, and more
  • Building RPMs: Source RPMs, spec files, RPM macros
  • Special considerations for dual architecture systems
  • Advanced functionality: Triggers and pre/post scripting

T8 Release Engineering and Project Lifecycle NEW!
Geoff Halprin, The Sysadmin Group, and Lee Damon, University of Washington
9:00 a.m.–5:00 p.m.

Who should attend: Software developers, system administrators, and managers who deal with internal or external project/product lifecycles and quality.

We will look at projects varying in scope from "Here's a new product we just bought; roll it out," through "We need an internal _foo_ server; make it happen," to "Here's this new thing we are developing; let's do it right so we can ship it." We will cover matters from quick projects to "This will take a year and 20 people to deploy."

The focus of this class will be on internally developed projects for internal use with some extrapolation to sold or shipped products. Large and small projects alike can benefit from proper planning and roll-outs. We will prove that the old adage, "There is never time to do it right, but there is always time to do it over," is never a good answer or a good philosophy. We will also examine the phenomenon of "Shoot the engineer and ship the product" in light of the reality most of us face: "The first 90% of the project takes 10% of the time; the remaining 10% takes 90% of the time."

Students should have a project or large task-set in mind when coming to the class. There will be break-out sessions where the student's real world tasks will be used as examples.

This is not intended to replace formal training for project planners. It is intended to make life better for people who deal with projects on a day-to-day basis. We will provide you with the ideas and some of the tools to take your projects from "We need this quick" to a supportable and released project—or even product.

Topics include:

  • Test planning and implementation
  • Project release planning
  • Project lifecycles
  • Replacement planning and updating
