Hi,
I have been working on conversion program from Informix to PostgreSQL db, and I
have a one table which has large data(bytea).

I need to be able to copy this one row (docdata column) that I have which is
close to 32MB. Program seems to read the data but cannot copy to postgres
(PreparedStatement), it gives OutOfMemoryError. I ran the program with these
heap too.
java -Xms200m -Xmx700m AddDoc
and I do not want to use LargeObject api (I do partion of data based on their
dates going from one table to many tables; data seems to be stored at
pg_largeobjects tbale). Here is the part of the code, and any help apriciated.
How do I copy large data like 32MB or greater?
Thanks

wbin = informixRs.getBinaryStream("docdata");
while ((wbyte = wbin.read ()) != -1) {
wbout.write (wbyte);
}
outln ("Size of KB is: " + wbout.toByteArray().length/1024);
size += wbout.toByteArray().length;
inp = new ByteArrayInputStream(wbout.toByteArray());
wbin = null;

postgresStmt = postgresConn.prepareStatement("INSERT INTO "+tableName+"
(id,docdata) VALUES (?,?)");
postgresStmt.setInt(1,id);
if(docdef_id.compareTo("12720") == 0 ) {
outln("\n\nbefore out of memory");
postgresStmt.setBinaryStream (2, inp, inp.available());
outln("\n\nafter out of memory");//cannot reach here
} else {
postgresStmt.setBinaryStream (2, inp, inp.available());
}
