Dear All,

     Database is containing Basic lobs of around 525GB and we are migrating to Securefile lobs 11gR2 but migration is running from one day still i can see the many datafiles are empty which we added to the existing tablespace for migration purpose. I think only 10% migration is finished.

How can i make it fast .. please guide.

Procedure :

CREATE TABLE BIO_SEC

(

BIO_ID          NUMBER(25),

a         NUMBER(14),

b          BLOB,

c          BLOB,

d       NUMBER(2),

e             BLOB,

f                BLOB,

g       NUMBER(2),

h             BLOB,

i                BLOB,

j            BLOB,

k         DATE,

l   VARCHAR2(20),

m         NVARCHAR2(8),

n    DATE,

o   NUMBER(12),

p         NVARCHAR2(30),

q       VARCHAR2(15),

Howdy, Stranger!
