On Linux and
Solaris operating systems, this command mimics the functionality provided
by the snapcore command on AIX® operating
systems.
The command extracts the shared objects list
section from the EDU trap file, combines the section together with
a core file and compresses the output into an archive which can be
sent to IBM Support
for analysis.
Authorization
One of the following authorities:
- Instance owners
- DBADM authority

Command parameters
- -c corefile | -corefile corefile
- Specifies a relative or absolute path to the core file.
- -t trapfile | -trapfile trapfile
- Specifies a relative or absolute path to the trap file.
- -m pmapfile | -mapfile pmapfile
- Specifies a relative or absolute path to the pmap file.
- -e executable_path | -executable executable_path
- Specifies a relative or absolute path to the executable file.
This file is either provided by IBM Support or obtained from the trap file under
the guidance of IBM Support.
- -o output_directory | -outdir output_directory
- Specifies an output directory for the compressed output file.
The specified output directory must exist.
- -p | -packCommand
- Compresses all files into an archive. On Linux operating systems, files are compressed
into a pax archive by default. On the Solaris operating system, the pax option
is not available and files are compressed into a tar archive by default.
- pax
- Specifies that the files are compressed using the pax (portable
archive exchange) command. On the Solaris operating system, the pax option
is not available.
- tar
- Specifies that the files are compressed using the tar (tape
archive) command. Requires the tar command to be
installed on the system.
- -v | -verbose
- Enables verbose mode.
Example
To
archive the extracted shared objects list section from an EDU trap
file or pmap file and a core file, issue a command like the following,
replacing core and trap file names as required:
- Linux
db2snapcore -corefile db2sysc.6270.98042.core -trapfile 28930.16.000.trap.txt -e ~/sqllib/adm/db2sysc
- Solaris
db2snapcore -corefile 21870.000.core -mapfile OSSNAPS/pmap.txt -e ~/sqllib/adm/db2sysc
Depending on which archiving method is used
(pax command or tar command),
the file name for the resulting archive is either db2snapcore.pax.gz or db2snapcore.tar.gz.
