DbEnv.set_error_stream

public void DbEnv.set_error_stream(OutputStream s)
	throws DbException

Description

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 application debugging.

The DbEnv.set_error_stream method is 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 <newline> character.

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.
