This is caused by a shortage of RAM on a dedicated (non shared server) environment.  Depending on your release of 


Oracle, you have several options:




Increase pga_aggregate_target


Decrease sort_area_size and/or hash_area_size


Move to multi-threaded server (a.k.a. MTS or shared servers)




游标(CURSOR)是指向一个称为上下文相关区的局域的指针,这个区域在服务器的处理过程在PGA内执行。
