ORA-12641错误出现的奇怪场景

jayli426

Every DBA should have some knowledge of the OS he works on.
If you don't know what setuid and setgid bits are,
I strongly suggest you find books or online documents to study it.
But working with a system admin helps too.

^_^哈哈
这季节为何这么多人爱当 老师，教训人啊
你怎么我不懂 setuid和setgid这玩意
《shell编程大全》不是专门有一章说这玩意嘛，可是说实话，我也确实不懂，因为在我看来，
setuid and setgid 适用的场景太少了，所以我都不记得了
是真的不记得了 。
干脆抄来书里的一段吧

chmod 4755 rws r-x r- x 文文件被设置了s u i d，文件属主具有读、写和执行的权限，所有其
他用户具有读和执行的权限
chmod 6711 rws --s --s 文文件被设置了s u i d和g u i d，文件属主具有读、写和执行的权限，
所有其他用户具有执行的权限
chmod 4764 rws rw- r- - 文文件被设置了s u i d，文件属主具有读、写和执行的权限，同组用
户具有读和执行的权限，其他用户具有读权限


我有个问题哦 rwxr-xr-x 和rws r-x r- x ，从实际效果到底有何不同呢？
如果我只想解决问题，而不考虑太多权限，是否一个chmod 777 就能解决所有的问题呢？
特别是仅仅处于开发阶段的时候。
setuid和setgid有其特别的应用场景，这个还真的想请你指导一下啊
(haha,我是求知者，非踢馆者)
