Define user-specified storage characteristics
You can define user-specified storage characteristics when you create a smart large object.
DataBlade API functions can specify the storage characteristics that Table 1 and Table 2 show. The user-specified storage characteristics apply only to the particular smart-large-object instance that is being created. They override any corresponding column-level or system-specified storage characteristics.
After you have an LO-specification structure allocated, you can
use the appropriate LO-specification accessor functions to set fields
of this structure. Accessor functions also exist to retrieve storage-characteristic
values from the LO-specification structure. When a smart-large-object
creation function receives the LO-specification structure, it creates
a smart-large-object instance that has these user-specified storage
characteristics.
Restriction: The LO-specification structure, MI_LO_SPEC,
is an opaque structure to DataBlade
API modules.
Do not access its internal structure directly. The internal structure
of MI_LO_SPEC might change in future releases. Therefore, to
create portable code, always use the LO-specification accessor functions
to obtain and store values from this structure.
The following sections describe how to access each group of storage characteristics in the LO-specification structure.
