ADAM Space Usage

I recently received a notification from our Server Administrators that
the available space on an ADAM server is running low. I have been
monitoring the server and noticed that the size of the .dit file has
not changed for several days, eventhough we add hundreds of records a
day. How is storage allocated to ADAM? Does ADAM allocate blocks of
storage, uses it as it seams fit and grabs additional blocks when it
determines it is running low? If so, how much does it allocate at a
time, xx kb, yy%?

Hi

the allocation will be dependent of the number of objects that are added to
the
DIT and how many of those objects fit into a database page; I'm guessing
that
the storage allocation will be chunked to a number of pages (8k each) plus
overhead for system tables.

Note that object deletions in the database will result in whitespace that
will get
reused. I usually tweak the garbage collection diagnostics as it provides a
useful check on allocations event log entry once a day:

Thanks. ADAM is the only thing on that server.
