本文详细解释了Oracle错误代码ORA-10226及其用途，如何通过该事件触发应用UNDO来生成CR副本，并在数据操作中进行SQL_TRACE操作。主要内容包括事件原理、输出形式以及实际应用场景。

Error:  ORA 10226
Text:   trace CR applications of undo for data operations
-------------------------------------------------------------------------------
Explanation:
        This is NOT an error but is a special EVENT code. It can be used
        to signal Oracle to perform SQL_TRACE actions.

	This event causes application of UNDO for producing CR copies of
	blocks. It can produce a lot of output (in the form of REDO
	application dump to rewind the block)
