Read and write smart large objects on an optical disc (UNIX)

Within a table, rows that include smart-large-object data do not include the smart-large-object data in the row itself. Instead, the smart-large-object column contains the LO-pointer structure. The LO-pointer structure can point to an sbpage in an sbspace or to a platter in an optical storage subsystem.

However, you can store smart large objects on optical disc only if this media is mounted as a UNIX™ file system and is write many (WMRM). The optical disc must contain the sbspaces for the smart large objects. Your application can use the API for smart large objects to access the smart large objects on the mounted optical disc.

The database server does not provide support for a write-once-read-many (WORM) optical-storage subsystem as a location for smart large objects. However, it does support access to simple large objects (BYTE and TEXT) on WORM media.
