Hi everyone..  I was trying to insert data from a table with LONG datatype into a NCLOB . Table with LONG column was around 1.5GB. Everything looked ok till I had inserted 100,000 records(1100 MB) or so , when the storage just shoots up , and table grows up by 3 GBs for the next 20,000 records . Can anyone please suggest something for this, is this a Data Storage problem ? These are the storage parameters of the LOB column in the table :

   LOB (LOB_NOTES) STORE AS
      ( TABLESPACE  G_DATA

       ENABLE      STORAGE IN ROW
        CHUNK       8192
        PCTVERSION  10
        NOCACHE
        STORAGE    (
                    INITIAL          64K
                    MINEXTENTS       1
                    MAXEXTENTS       2147483645
                    PCTINCREASE      0
                    FREELISTS        1
                    FREELIST GROUPS  1
                    BUFFER_POOL      DEFAULT
                   )

Any suggestion would be of help...
