 ## <a id="core_file_definition"></a>Core file

 A core file is a disk file that records the memory image of a running process in the event the process crashes or terminates abruptly. The information in this image is useful for debugging the state of a process at the time when it was terminated.

 ## <a id="packcore_definition"></a>Packcore

 The packcore utility helps pack a core file with its context, including the executable, application, and shared system libraries from the current environment. This information can be unpacked for later debugging on a different system. Packcore extracts the name of the binary that generated the core from the core file, then executes ldd (List Dynamic Dependencies) to create a single tar archive containing the core file information.

 ### <a id="using_packcore"></a>Using packcore

 The packcore utility is located under `${GPHOME}/sbin`. Run one of the following commands to pack a core file:

 ```shell
 $ $GPHOME/sbin/packcore <core_file>
 ```

 or

 ```shell
 $ $GPHOME/sbin/packcore -b|--binary  $GPHOME/bin/postgres <core_file>
 ```

 Alternatively, you can navigate to `$GPHOME/sbin` and run the following:

 ```shell
 $ ./packcore <core_file>
 ```

 or

 ```shell
 $ ./packcore -b|--binary $GPHOME/bin/postgres <core_file>
 ```
 When processing is completed, the utility creates a tar file in the format: packcore-<core_file>.tgz. Unpack this file on another system to use it for debugging.
