derby.infolog.append

The derby.infolog.append property specifies whether to append to or overwrite (delete and recreate) the derby.log file when the Derby engine is started.

The derby.log file is used to record errors and other information. This information can help you debug problems within a system.

You can set this property even if the file does not yet exist; Derby creates the file.

See derby.stream.error.style for information on how this property works if the derby.stream.error.style property is set.

Default

False.

By default, the file is deleted and then re-created.

Example

derby.infolog.append=true 

Scope

system-wide

Dynamic or static

This property is static; if you change it while Derby is running, the change does not take effect until you reboot.
