Dump files

Dump files are created when an error occurs for which there is additional information that would be useful in diagnosing a problem (such as internal control blocks). Every data item written to the dump files has a timestamp associated with it to help with problem determination. Dump files are in binary format and are intended for IBM Software Support representatives.

When a dump file is created or appended, an entry is made in the db2diag log file indicating the time and the type of data written. These db2diag log entries resemble the following example:

2007-05-18-12.28.11.277956-240 I24861950A192 LEVEL: Severe
PID:1056930 TID:225448 NODE:000 Title: dynamic memory buffer
Dump File:/home/svtdbm5/sqllib/db2dump/1056930.225448.000.dump.bin

Note: For partitioned database environments, the file extension identifies the partition number. For example, the following entry indicates that the dump file was created by a Db2® process running on partition 10:

Dump File: /home/db2/sqllib/db2dump/6881492.2.010.dump.bin
