Storage characteristics tell the database server how to manage
a smart large object. These characteristics include such areas as
sizing, logging, locking, and open modes. You have the following options
with respect to storage characteristics:
Use the system-specified storage characteristics as a basis for
obtaining the storage characteristics of a smart large object.
Override the system defaults with one of the following:
Storage characteristics defined for a particular CLOB or BLOB
column in which you want to store the smart large object
Storage characteristics that are unique to a particular CLOB or
BLOB column called column-level storage characteristics
Special storage characteristics that you define for this smart
large object only called user-specified storage characteristics
The database server uses a hierarchy, which the following figure
shows, to obtain the storage characteristics for a new smart large
object. Figure 1: Storage-characteristics
hierarchy
For a given storage characteristic, any value defined at the column
level overrides the system-specified value, and any user-level value
overrides the column-level value. You can specify storage characteristics
at the three points shown in the following table.
