设置用户标识符
A program is usually run under the UID of the person who executes it (emacs, gcc, vi) except those that need to do special things (passwd, chsh) that are run as setUID root. 程序通常在执行该程序（emacs, gcc, vi)的用户UID下运行，除非该程序需要通过设置根用户UID（即SetUID）来运行一些特定的任务（passwd, chsh）。
Possibly it is not SetUID root. 可能该程序未被 SetUID root。
Oracle utilizes shared memory segments to perform its interprocess communication, and unless the oracle processes run as setuid oracle,they will be unable to attach to Oracle's shared memory segments. 免责：本站所有资源均索引于网络，如果你觉得相关资源侵害了你的权益，请通知我们。
