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...

Pkg_app in a Clustered Environment

Hello all,

I was recently contacted by a Sun Customer Advocate regarding Pkg_app, Dirtracer and Clustered environments.

First some up front info on Pkg_app.  Pkg_app was originally created by Rick Zagorski and I took over its development in 2006.  I took what Rick had coded and added to it specifically (at the time) to help with Directory Server core/gcore files.  This was released as pkg_app 2.0 and was a mash of Ricks code with some additions of mine.  As you know I created Dirtracer (Stracer) in 2004 and continue its development to help customers gather data on their Directory Server problems. 

The Customer was having issues with Pkg_app and Dirtracer when they attempted to use it in a Clustered Environment.   Even though the customer was running an old version of Pkg_app, Pkg_app and Dirtracer are "not" tested nor certified for use in a Clustered Environment.  I've have only had one prior request to have pkg_app/dirtracer be Cluster aware so it has not been on the top of the revision list.

I will be revamping the Pkg_app code to take into account all libraries etc. that Pkgcore gets for use with Java Cores and will look into the Cluster issue.

More news on this later.
