DB2 Version 9.7 for Linux, UNIX, and Windows

FP4: New configuration parameter reduces risk of losing diagnostic data

In Version 9.7 Fix Pack 4 and later fix packs, you can specify an alternative path to a directory where DB2® diagnostic information is stored by using the new alt_diagpath database manager configuration parameter. The alt_diagpath database manager configuration parameter is used only if DB2 cannot write to the path set by the diagpath database manager configuration parameter.

If DB2 fails to write to the directory that you specify by using the diagpath configuration parameter, important diagnostic information might be lost. To reduce the chances of losing diagnostic information, you should set the alt_diagpath configuration parameter, which does not have a default value. If you set the alt_diagpath configuration parameter to the same path that you use for the diagpath configuration parameter, an error message is generated. Also, you should not set the diagpath and alt_diagpath configuration parameters to the same file system. If you do, a warning message is generated.
