core_xxx directory without core

Hi

       Today in my oracle's cdump directory, there are many core_xxx directories without core

    and some core_xxx directories with core(this is another problem).

       In the udump directory, there are .trc files which number is nearly same as the real cores.

       In the alert.log, there are also entries which number is nearly same as the real cores.

      So where did these core_xxx directories without core come from? Received on Mon Nov 19 2007 - 06:11:26 CST
