The PKGCore.zip includes pkgcore for Linux, HP-UX, and Solaris. 
 NetWorker (Linux): How to copy files to/from a Linux NetWorker server.

General Use Instructions.

1. Copy linux_pkgcore.sh to a Linux machine where the core file that you would like to debug resides.
2. Run: 
linux_pkgcore.sh output_file_name /path/to/core_file /path/to/binary
Example: 
pkgcore.sh LGTsc12345 /nsr/cores/nsrd/core.#### /usr/sbin/nsrd
NOTE: The overall syntax is the same for HP or Solaris systems; however, instead of linux_pkgcore.sh, use hp_pkgcore.sh and solaris_pkgcore.sh where appropriate.
3. Obtain the resulting output files <output file name>_corefiles.tar.gz and <output file name>_libraries.tar.gz and upload these to the service request.

Additional Information

Analysis

1. Decompress both output files in the same path on the machine when you intend to debug the core.
2. If the binary that produced the core is nonstripped, replace the binary file that is linked to by the "executable" symbolic link, with a nonstripped binary.
3. Ensure that gdb is in your system path.
4. In the directory where you decompressed the output files, run ./opencore
