This parameter specifies the type of errors that are written. For a server of the satellite node type, errors are written to the notification file called instance.nfy. For all other node types, this parameter is only available on the Windows NT platform, and errors are written to the Windows NT event log. The errors can be written by DB2, the Capture and Apply programs, and user applications.
Valid values for this parameter are:
0 - No diagnostic data captured
1 - Severe errors only
2 - All errors
3 - All errors and warnings
4 - All errors, warnings, and informational messages
For a user application to be able to write to the notification file or Windows NT event log, it must call the db2AdminMsgWrite API. For more information about this API, refer to the API Reference.
Recommendation: You may wish to increase the value of this parameter to gather additional problem determination data to help resolve a problem.
