谁能帮忙解释下各个列的意思，及怎么看（如：oracle 共享库装载的起点），先谢了！

千问 · 2007-10-20 08:38:44

应该是进程4964对应的内存空间及权限信息
按照网上的文档：
b7ffe000-b8000000 应该是地址
第二列是权限
08:02 是主次设备号
/lib/tls/libm-2.3.4.so 列是加载的类库什么的

研究这些有必要吗？找Linux开发的论坛问问去吧

千问 · 2007-10-20 08:38:44

呵呵，谢谢！b7ffe000-b8000000 是某段地址吗，rw-p是权限，有个p是什么意思，其他的呢

千问 · 2007-10-20 08:38:44

呵呵，microsoft_fly兄弟，你在这问，不如去linux版问吧

千问 · 2007-10-20 08:38:44

呵呵，谢谢foxmile 帮我顶，继续
