Examples with InternalDriver org.apache.derby.iapi.jdbc.InternalDriver used on opensource projects

Example 1 with InternalDriver

use of org.apache.derby.iapi.jdbc.InternalDriver in project derby by apache.

the class SlaveDatabase method handleShutdown.

/**
 * Used to shutdown this database.
 *
 * If an error occurs as part of the database boot process, we
 * hand the exception that caused boot to fail to the client
 * thread. The client thread will in turn shut down this database.
 *
 * If an error occurs at a later stage than during boot, we shut
 * down the database by setting up a connection with the shutdown
 * attribute. The internal connection is required because database
 * shutdown requires EmbedConnection to do cleanup.
 *
 * @param shutdownCause the reason why the database needs to be
 * shutdown
