Database journal storage

The Content Manager OnDemand database includes recovery journal and journal receivers which are used to recover from application or system errors.

In combination with database backups, they are used to recover the consistency of the database right up to the point in time when an error occurs. When you create a Content Manager OnDemand instance, a journal called QSQJRN is created in your instance library. A journal receiver called QSQJRN0001 is automatically created as the first receiver for the journal. QSQJRN is a system-managed journal, which means that the operating system manages the changing of journal receivers as needed. Messages related to this journal are sent to the QSYSOPR message queue.
