The Talks:
Solaris Dynamic Tracing - Dtrace
DTrace
is a revolutionary observability tool introduced in Solaris 10, and
currently available in all Solaris 10 releases, OpenSolaris, Mac OS X
10.5 and FreeBSD 7.2. DTrace provides unprecedented observability of
the kernel and the entire application software stack without requiring
code modifications. It is completely dynamic, and introduces zero probe
effect when no DTrace probes are enabled.
This talk will
introduce the basic components of DTrace - Providers, Probes,
Predicates, The D Language, Actions and Subroutines and DTrace
variables. We will then dive into examples of DTrace one-liners and
scripts that demonstrate the use of DTrace of understanding and
root-causing system and application performance issues.
Jim Mauro is a Principal Engineer in Sun Microsystems Systems Group, where he focuses on performance of volume commercial workloads on Sun technology. Jim co-authored Solaris Internals (1s Ed), Solaris Internals (2nd Ed), Solaris Performance and Tools (1st Ed) and is currently working on a DTrace book.

LDOM Domains and ZFS: An example of creating a ZFS bootable root LDOM
domain using jumpstart
Using
Version 101009 of Sun Solaris on a Sparc T5120 with LDOM 1.2, Shannon
Sylvia creates guest domains that are each independent of each other.
Each guest domain contains its own separately configured operating
system and its own virtual disks. Using a "cookbook" approach, new
guest domains can be easily added and configured, or removed without
affecting the control domain or any of the other guest domains. Each
domain is created using ZFS as the root, bootable volume.
Shannon
will provide examples on how the control domain, the jumpstart/boot
server, and the guest domains should be configured.
Shannon Sylvia has 15+ years experience as a Unix Systems Administrator.
She
is responsible for installing and maintaining Solaris, AIX, and Linux
at Northeastern University. In addition, she is an adjunct professor
at Northeastern University's College of Professional Studies.
She has a strong interest in IT in the health field, and has recently completed 2 1/2 years of nursing school and clinicals. She is currently involved in volunteer work including Salesforce and website development.
She
earned a bachelor's degree in Computer Science from National
University, a bachelor's degree in English from San Diego State
University, and a Master's Degree in Computer Information Systems from
Boston University.
