Mounting Workspaces as Drives: Lettered versus Letterless

Both core database and journal file are used for engine operations, like ingest, searching, or
deletion. The integration of data in the journal file into the core database is happening constantly
in a background thread.
The journal file can grow in size when the Interplay Engine is extremely busy (for example,
during a database schema upgrade), but will eventually shrink back to its default size (8 MB for
the CCS database _InternalData, 32 MB for AvidWG and AvidAM). Journal integration is no
longer suspended when a backup is performed. Therefore, journal data does not accumulate
when a backup is running.
If a Severe Error Occurs
If a severe error occurs during integration of journal data into the core database, the Interplay
Engine suspends the integration. Such severe error cases include:
Failure of integration of journal data into the core database
Failure to read/write from the journal file
Failure to do deletes in the streamed property store (this is a central step in the journal
integration)
Usually in such cases, the Interplay Engine rejects all further write operations and reports an
error code in the server log and to the clients trying to perform write operations. There are cases
where the Interplay Engine can continue operating and adding data to the journal file, but this
data is not integrated into the core database.
Journal integration relies on disk access to the _Database folder at all times.
There is one point in time when the engine relies on the journal integration to be finished (at all
other times it is done in a parallel thread). This one point is when a database is loaded, for
example, when a database is brought up, a failover was triggered, or a cluster was taken offline
and back online. At this point, when the database is loaded, the journal integration is enforced.
Integration needs to go through and finish so that the database can be cleared and go online (be
accessible by clients).
Mounting Workspaces as Drives: Lettered versus
Letterless
Avid editing applications, Interplay Assist, and Avid Instinct require Avid shared storage client
software to function as clients in an Avid Interplay workgroup. Explicit mounting of workspaces
as drives might or might not be necessary, depending on your particular workflow. In general,
there is no harm in mounting the workspaces that you need.
