Error when inserting file 4KB in a BLOB column.

Question

Hello,
I am getting the following error when I am trying to insert a file > 4KB in a
BLOB column.
ORA-01461: can bind a LONG value only for insert into a LONG column.
We are using Weblogic5.1.0 sp10, Oracle 8.0.5 with WL OCI driver.
There is no change even after setting the following property weblogic.oci.min_bind_size=660
Please can anyone help?
Thanks.

Hello,
I tried using the following sql stmts to override the NLS_LANG setting on both
server and client for a session.
ALTER SESSION SET NLS_LANGUAGE = AMERICAN;
ALTER SESSION SET NLS_TERRITORY = AMERICA;
It still gave the same error.
I tried the same using Oracle thin driver.Even then the same problem.
As I mentioned earlier, we are using oracle 8.0.5.
and here is the code I am using for writing BLOB data
java.sql.PreparedStatement prepstmt = conn.prepareStatement("Update TEST_BLOB
set BLOBATTACH = ? where IDX =1");
ByteArrayOutputStream ostream = new ByteArrayOutputStream();
ObjectOutputStream p = new ObjectOutputStream(ostream);
p.writeObject(data);
prepstmt.setBinaryStream(1, new ByteArrayInputStream(ostream.toByteArray()), ostream.size());
prepstmt.executeUpdate();
prepstmt.close();
Any suggestions ?
Thanks.

Latha,
You need to make sure you have the same NLS_LANG setting both for the
client
and the server.

Same code is working fine for files less than 4000 bytes.
Oracle table has only one BLOB column.
I have set weblogic.oci.selectBlobChunkSize=1200 .
Where could be the problem?

We resolved the problem as following:
ps = con.prepareStatement
("update tq_businessmodel set

"WHERE taskid=?");
ByteArrayOutputStream ostream = new ByteArrayOutputStream();
ObjectOutputStream p = new ObjectOutputStream(ostream);
p.writeObject(businessModel);
ps.setBinaryStream(1, newByteArrayInputStream(ostream.toByteArray()),
ostream.size());
ps.setTimestamp(2,new Timestamp(System.currentTimeMillis()));
ps.setLong(3,taskid);
ps.executeUpdate();
