Oracle LOB data can exist in several formats in Oracle. The LOB datatypes in Oracle are:
character
LONG
CLOB
NCLOB
binary
LONG RAW
BLOB
BFILE
BFILE points to file contents stored outside of the Oracle database.
For those types stored in the database (all types except BFILE), Oracle records the content of the LOB in the redo files. The Mirror Replication Agent reads the LOB data from the redo file and submits the data for replication.
Replication of BFILE datatypes
is not supported.
