Pkgapp 3.0 code has been finalized!

Pkgapp3 is the latest update to the Sun GDD tool set. These tools are designed to help customers gather the data needed for the best possible support on their issues.

Pkgapp is a shell tool built by Sun Support Engineering to help gather all OS and application libraries used by Sun Java Systems (and others) servers at runtime.  Pkgapp can be used to gather these libs, etc, from cores produced by crashes or gcores captured manually by administrators.

Pkgapp is part of the GDD (Gathering Debug Data) suite of tools and has been used for years to help Sun Support debug tricky crashes, as well as performance and memory leak problems where cores or gcores are available.

New major features in Pkgapp 3.0:

1) Now handles Java Cores and grabs jstack and jinfo.
 - See the -j and -J options

2) Includes all functionality that was available in both pkg_app 2.7 and pkgcore.

3) Can allow for the temporary files to be retained in /tmp
 - See the -r option

4) Allows pkgapp3 to be placed in a $PATH location; can now be run from any location.

5) Can use relative paths for the following options:
 -c <core file OR pid of a running process>
 -p <full path to, but not including the process binary> (ns-slapd, imapd, httpd etc.)
 -s <Storage; path to store the final tar file in>

6) Retains all lib/binary paths (pkgcore) as well as the pkg_app app/ location for older pkg_app aware applications.

7) Names the final storage path as pkgapp-<date>-<index> to help administrators locate the final tar file faster.
 - Ex: pkgapp3-111708-01/

8) Gathers the following Solaris only proctool commands from the core.
 - pldd
 - pstack
 - pmap
 - pcred
 - pflags
 - pargs

9) Checks to see if the core file is truncated and checks the core files cksum to ensure the file size match.

10) Gathers the following core and pkgapp3 specific data
 - core file cksum
 - core file truncation (good/bad)
 - core file size (ls -l)
 - library list (from the pldd)
 - manifest log (all files included int he final tar)
 - pkgapp3 arguments used.

11) Gathers the following OS specific data
 - coreadm info
 - date/time
 - messages (from /var/adm)
 - pkginfo
 - showrev -p
 - /etc/release (Solaris)
 - ulimit
 - uname -a

12) Creates a coreinfo.sh script to allow Sun Engineers to quickly run "coreinfo" for ns-slapd processes (only).

13) Alerts administrators they must upload 2 files (pkgapp tar & core) separately when they do not use the -i (include core) switch.

14) Will exit with a fatal error if a pldd cannot be properly retrieved from the core and alerts the administrator to run pkgapp3 using a pid as the -c option.

15) Saves the pkgapp3 arguments and runtime log into /var/tmp/pkgapp-history/.  Helps administrators and pkgapp see previous runs.

16) Updated usage and alert messages.

 Here are a couple previews of how the new code works.

 Example: Usage output

\* ----------------------------------------------------------------------------------
\* Sun Microsystems RSD pkgapp 3.0 Solaris                               [11/24/2008]
\* ----------------------------------------------------------------------------------
pkgapp 3.0, a Sun Microsystems data gathering utility.
Usage:
  pkgapp [options] -c <core file | pid> -p <full path (path only) to process binary> -s [path to write tar file]

Required parameters:
 -c <core file OR pid of a running process>
 -p <full path to, but not including the process binary> (ns-slapd, imapd, httpd etc.)

Optional parameters:
 -i (Include a previously generated core file with the final tar.gz)
 -j (Javacore; process a java core)
 -r (Remove all temp files)
 -q (Quiet)
 -d (Debug)
 -J <JstackPath; path to the jstack (jdk) commands>
        defaults to /usr/jdk/instances/...
 -s <Storage; path to store the final tar file in>

usage:  pkgapp -c <name of the core file> -p <path to process binary>
usage:  pkgapp -c <pid of the running app> -p <path to process binary>

Examples: these are examples mixing various parameters

Directory Server
pkgapp -i -r -c ./core.14740 -p /var/mps/ds52p4/bin/slapd/server/64

Messaging Server
pkgapp -c ./core.3496 -p /opt/SUNWmsgsr/lib

Web Server
pkgapp -c ./core.1092 -p /space/iws70/lib -s /var/crash

Calendar Server
pkgapp -r -c ./core -p /opt/SUNWics5/cal/lib

Sendmail
pkgapp -i -c 512 -p /usr/lib

Mysqld
pkgapp -i -r -c ./core -p /support/mysql-5.0.41/bin

Comments:

Does this only work on Solaris?

Hi Mathew, so far yes, this is only available on Solaris. I will be porting the code to Linux and HP-UX soon.
