Each Object storage group consists of a DB2 database. The DB2 database
is referred to as the
object storage database.
The object storage database contains the following DB2 tables:
- An object directory containing entries for objects residing in
a particular Object storage group. These entries contain control information
needed to locate and manage the object.
- A storage table for objects less than or equal to 3980 bytes.
- A storage table for objects greater than 3980 bytes and less than
or equal to 256 MB (268,435,456 bytes).
- A LOB storage table (LOB storage structure) for objects greater
than 32,640 bytes. The LOB storage structure is optional for objects
greater than 32,640 bytes and less than or equal to 256 MB. The LOB
storage structure is required for objects greater than 256 MB and
less than or equal to 2000 MB (2,097,152,000 bytes).
