The SQL Anywhere database delete_old_logs option is set to Off by default. If you set the default to on, the LTM automatically deletes the old transaction logs when Replication Server no longer needs access to the transactions. This option can help to manage disk space in replication setups.
For example, set the delete_old_logs option for the PUBLIC group:
SET OPTION PUBLIC.delete_old_logs = 'ON'
SET OPTION PUBLIC.delete_old_logs = '10 days'
