public void DbEnv.set_error_stream(OutputStream s)
When an error occurs in the Berkeley DB library, an exception is thrown. In
some cases, however, the errno value may be insufficient to
completely describe the cause of the error, especially during initial
The DbEnv.set_error_stream and Db.set_error_stream methods
are used to enhance the mechanism for reporting error messages to the
application by setting a OutputStream to be used for displaying additional
Berkeley DB error messages. In some cases, when an error occurs, Berkeley DB will
output an additional error message to the specified stream.
The error message will consist of the prefix string and a colon
(":") (if a prefix string was previously specified using
DbEnv.set_errpfx), an error string, and a trailing
Alternatively, you can use the DbEnv.set_errcall method to capture the
additional error information in a way that does not use output streams.
You should not mix these approaches.
This error-logging enhancement does not slow performance or significantly
increase application size, and may be run during normal operation as well
as during application debugging.
