It is important to set the value of OPEN_CURSORS high enough to prevent your application from running out of open cursors. The number will vary from one application to another. Assuming that a session does not open the number of cursors specified by OPEN_CURSORS,there is no added overhead to setting this value higher than actually needed. 没影响,一般写的好的程序,不会过度使用cursor。
