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 behaviour 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.
