DBMS_BLOB: ORA-22297: warning: Open LOBs exist at transaction commit time

Question

Hello
I've written this to get to understand BLOBS. I had intended it to take a VARCHAR2 string, convert it to RAW and write the contents to a blob.
However, DBMS_LOB.Write()) returns the error message "ORA-22297: warning: Open LOBs exist at transaction commit time". Can somebody put me right? Just why is this being returned?
Thanks in advance, Aidan
INSERT INTO BINARY (PK ,
BLOBDATA )
VALUES (1 ,
Empty_Blob());                         
/* Lock the row. */
SELECT BLOBDATADATA INTO V_Blob FROM BINARY WHERE PK = 1 FOR UPDATE;                                             
/* Open the Lob. */
DBMS_LOB.OPEN (V_Blob, DBMS_LOB.LOB_READWRITE);
DBMS_LOB.WRITE (V_Blob ,
V_Length ,
     V_Offset ,
UTL_RAW.CAST_TO_RAW (p_Data));
DBMS_LOB.CLOSE (V_Blob);

I am assuming there are some permissions problems
I have DBA role in Database
We are on databasae > 11 (11.0.2 i think)
My database DBA installed 4.2.2 but does know APEX real well he installed becasue he has SYS password which I am not privy to.
I was able to install Pacakaged appliaction.
Kind of Lost from Here.......
