If you are using licensed programs or system functions that require these journals, consult the documentation for those functions for instructions on how to manage the journals and journal receivers.
In general, you swap journal receivers to detach the journal receiver and create and attach a new receiver on a regular basis. You may need to save detached receivers before deleting them, or you may be able to delete them without saving them. This depends on how the journal receivers are being used and whether the journal is using system journal-receiver management.
In some cases, you can use the automatic cleanup function of Operational Assistant to remove detached journal receivers that are no longer needed.
