JDBC Connectivity - broken pipe received when SQL server resets the connect
Hi,
We have downloaded MICROSOFT SQL SERVER 2000 DRIVER for UNIX boxes
when i try to connect using JDBC , with all parameters
user id, driver, password etc
at the sniffer(TCPIP) level when the jdbc connection is attempted
i see a
1) SYN packet to the SQL server from unix box
2) ACK SYN from the SQL server to unix box
3) ACK from unix box to server
4) no activity for about a minute
5) a RST( reset ) from SQL server to unix box.
at this point i get the following
stack trace
java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Broken pipe or
no reader on socket
