There is no mechanism in Genesys version 6.1, it has been implemented in version 6.5 of the management layer. Otherwise if you’re using version 6.1, you can use the following script.
delete from g_log_messages
where timewritten < to_date(‘(your date in format DDMMYYYY)’, ‘DD/MM/YYYY’);
This script allows you to delete log messages in the log DB that are older than the date specified. It has been tested on an Oracle DB.
