Oracle Forms Builder中，常會出現等待後臺調用pck或者等待請求運行的情形。
等待過程中，爲了更友善地展現當前狀態，防止用戶方誤操作，常會使用變更鼠標形態的方式。
oracle form內置函數 SET_APPLICATION_PROPERTY 的 CURSOR_STYLE 屬性可以實現這一功能。
SET_APPLICATION_PROPERTY(CURSOR_STYLE, 'BUSY'); --忙碌狀態 SET_APPLICATION_PROPERTY(CURSOR_STYLE, 'DEFAULT'); --普通狀態
比如，WIN Aero鼠標方案，忙碌狀態爲有個轉動的圓圈。
