Using the DELETE_OLD_LOGS option

The DELETE_OLD_LOGS Adaptive Server Anywhere database option's default is OFF. If you set the default to ON, then 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.

You set the DELETE_OLD_LOGS option for the PUBLIC group:

SET OPTION PUBLIC.DELETE_OLD_LOGS = 'ON'
