Pkgapp 3.2 for Solaris released!

Hi all!

Pkgapp 3.2 is available internally...yeah!

Artistic Bridge

I finally had time to update the Pkgapp documentation and retest it on various application cores/gcores and it is now ready for prime time.  I have also submitted it to BigAdmin and it should be available in the next few days.  If you need it now, please contact your favorite Sun Support representative and request he send it from the internal download site.  I will also update "this" post once Big Admin has uploaded the new version.

Pkgapp 3.2 has 2 big new features...

  1. It includes adm64 libraries that were previously not included making debugging easier on that platform for java issues.
  2. It includes a new core truncation feature developed by a member of the Directory Server Sustaining team.  The great news is, the feature not only works on Directory Server cores but any other core/gcore you may be dealing with!

If the core/gcore is good, the user is given the following message:

\* Checking if corefile is truncated     [CORE gcore.cshttpd.28734 GOOD Core contains 293 segments ]

If the core is truncated, the user is alerted and required to answer yes/no as to whether they understand the data may be totally unusable.

\* Checking if corefile is truncated     [WARNING! core gcore.cshttpd.28734.truncated is truncated (40396864d bytes instead of 40397397d bytes)]
\*                                     
\* ALERT! The core was found to be truncated, it therefore may not be usable
\* pkgapp will continue to gather data and you can still upload the result to Sun
\*                                     
\* Do you understand the core may not be usable? [yes|no] yes
                                        [Answer was -> yes]
\* Continuing...

The Dirtracer Blog is here!

Welcome to the new Dirtracer Blog!


I am Lee Trujillo, an Engineer supporting the Sun Java Directory Server since December 2003.  I am also the creator of Dirtracer, Sun's number one tool for tracing issues for our Sun Directory Server.

Early in 2004, I saw that the support organization had no formalized standard for asking for and obtaining data related to issues surrounding the Directory Server, so I created Stracer (Stack Tracer), the predecessor to Dirtracer (Directory Tracer).  Stracer 1.0 consisted of 169 lines of shell script that basically gathered pstacks, prstats and top output from a running ns-slapd process.  Conversely, Dirtracer 6x (2008) is a complex 2,590 line script of functions that can be combined in many ways to gather Directory data based on problem type.

Dirtracer is a troubleshooting tool designed to help reduce resolution time on complex Directory Server problems and to ease the data-gathering process for Sun's customers.

Dirtracer is part of the GDD (Gathering Debug Data) suite of tools and has already been used for years to tackle some of the most persistent, difficult Sun Java Systems Directory Server problems faced in the field.  For problems such as server hangs, crashes, and high cpu utilization, Dirtracer simplifies the sampling of system resources and crash data in order to help identify trends.

Save you and your customers time and aggravation -- discover the power of Dirtracer.

I expect Dirtracer version 6.0.6 to be available later today on the external Big Admin Administration Portal site for Customer and partner download.
