I don't know if you have ever used the AIX operating system, so how to check some computer parameters? Can you use commands? Let me introduce the method of viewing physical memory under AIX operating system. I hope it will be helpful to you!
View several commands of Aix operating system CPU
If the system is AIX 5L
#prtconf | more
#lsconf
#sar -u 1 10
There are many commands in the system to check the number of CPUs, but which command outputs the number of logical CPUs and which is the number of physical CPUs? Let me make a brief introduction. answer:
From AIX 5 Since 3, for power5 machines, the system has introduced the function of SMT (simultaneous multi threading), which allows two processing threads to run on the same processor. For the operating system, a physical processor will logically become two processing units (logical processors). That is, when the SMT function is enabled, the number of logical CPUs is twice the number of physical CPUs, while when the SMT function is disabled, the number of logical CPUs is equal to the number of physical CPUs.
How to view the physical memory size of AIX
The memory utilization of Aix cannot be observed through general Topas and vmstat.
Because IBM's memory management is very special, first understand the memory division, and pay special attention to the management mode of file memory.
It can be calculated through the data displayed by svmon.
Vmstat - V can output a status of memory. The num perf, Num client, free page and other related data can give an overview of the current memory of Aix.
Netstat - V, which is similar to vmstat - V, can output the status of the network card. When checking whether there is a problem with the quality of the network connection, you can refer to the relevant output data.
Other useful are iostat, lvmstat, etc. you can refer to the AIX Command Reference Daquan for corresponding help.
