Valid values for this parameter are:
- 0 – Starting in Fix Pack 1, only administration notification messages are captured on the client side. Critical errors, event messages, and administration notification messages are still captured on the server side.
- 1 – Only severe errors, critical errors, event messages, and administration notification messages are captured.
- 2 – All errors, event messages, and administration notification messages are captured.
- 3 - All errors, warnings, event messages, and administration notification messages are captured. Some key informational messages might be captured at this level as well.
- 4 – All errors, warnings, informational messages, event messages, and administration notification messages are captured.
The diagpath configuration parameter is used to specify the directory that will contain the error file, alert log file, and any dump files that might be generated, based on the value of the diaglevel parameter.
Usage
notes
- The dynamic behavior for diaglevel does not extend to all processes.
- The db2sysc Db2® server process can detect dynamic changes, for example, when you issue the UPDATE DATABASE MANAGER CONFIGURATION command over an instance attachment.
- When Db2 client and application processes start, they use the diaglevel configuration parameter setting and do not detect any dynamic changes.
- To help resolve a problem, you can increase the value of this parameter to gather additional problem determination data. Setting diaglevel to 4 might affect performance adversely. You should only do so during the specific period of problem diagnosis or under the guidance of support.
