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 DB2(R) customer support representatives.
When a dump file is created or appended, an entry is made in the db2diag.log indicating the time and the type of data written. These db2diag.log entries resemble the following:
1997-03-16-11.53.18.001160Instance
