org.postgresql.util.PSQLException: An I/O error occured while sending to..

772199Nov 18 2010 — edited Nov 26 2010
Hi,
I have a Java console application which copies data from a PostgreSQL database to an Oracle database. I'm trying to copy a big table with 121,681,835 rows but the program fails after copying 8,760,000 rows. The SELECT fetch is 60,000 and QueryTimeOut is set to 0. I'm using postgresql-8.4-701.jdbc4.jar driver and springs framework 2.5.6. Below is the error stack

Can anyone provide some insights on this error ?

Thanks,

I could overcome this problem after removing the sslfactory parameter from the connection parameters.

It's an SSL problem, not a DBMS problem. Something is wrong with your SSL setup. We need to see more of the stack trace.
