cached:出现在Swap,实际上是要从硬盘读入内存的数据,由于再读一次硬盘速度会很慢,虚拟内存就将一些次重要的文件放在cached,让二次读取同样数据时间会更快一点。 PID USER PR NI VIRT RES SHR %CPU %Mem Time+ COMMAND 标题够长的,实际要弄清楚的是各种标记的意义。 PID:进程id USER:运行的
TIME+: 进程使用的cpu时间总计 COMMAND: 拉起进程的命令 对输出结果进行排序top输出的下半部分有很多进程信息列,我们可以根据这些列对进程输出进行排序,默认情况下根据cpu使用率对进程排序。在top命令执行时,按”O”,可以看到排序项以及相应的按键:各项默认以从大到小排序,top运行中,按”R”可反向显示输出结果。 ...

The DISCONNECT command in Example 15-1 actually ends the sessions, not the connection. Opening a new terminal and connecting to the instance as a different user, the query in Example 15-2 shows that the connection from Example 15-1 is still active. Example 15-2 Connection with No Sessions...
View the process dynamically with the top command(用top命令动态查看进程) While the ps command can reveal a lot about what the machine is doing,it provides only a snapshot(快照) of the machine's state at the moment the ps command is executed.To see a more dynamic view of the machine's...
