Last updated on AUGUST 12, 2016

Applies to:

Oracle Rdb Server on OpenVMS - Version 7.3.0.2 to 7.3.0.3 [Release 7.3]
Oracle JDBC for Rdb - Version 7.3.0.2 to 7.3.1.0 [Release 7.3]
Information in this document applies to any platform.

Symptoms

Using JDBC for Rdb 7.3.0.3, long running queries let the client fail after 25 minutes with:

Connection lost : java.io.EOFException


The JDBC MP server does not know that the client has disconnected and the server process continues IO processing.

Changes

Upgrade to JDBC for Rdb 7.3.0.3.

The problem did not occur in JDBC for Rdb 7.3.0.1 and older. The problem was hidden in JDBC for Rdb 7.3.0.2 by the following bug:
