1, use the shortcut key: Win+r Open the Command window.Press ENTER to command interface2, pop up the following command interface, enter WMIC memphysical get maxcapacity at Interface c:\users\administrator>3. If there is a value4, the calculated value divided by 1024 is the M-unit, and then divided by 1024 is the G units, such as16, indicating that the computer supports up to 16G of running memoryCompy updated on: 2017-07-29 08:16 qq:2071959367Windows system view supports
The memory here is logical, that is, virtual. is not a physical memory space. The actual implementation of the logical memory when the physical memory is not sufficient to use secondary storage (hard disk).Some people naturally ask: since you can use the secondary virtual, then each process does not want to how big vir
A new requirement was received in the previous two days to monitor the maximum number of MongoDB connections, memory usage, etc. in the Linux shell script.
But I do not understand the Linux Shel, just a few simple common Linux operations, as long as a wild search, and finally many attempts to finally get these values.
The steps for success are as follows:
0,
Write a line of data that MongoDB monitors into a
Fault Description:when you remotely adjust the instance memory, the maximum memory is adjusted to 0, so the maximum RAM becomes the minimum value of 128MB. How to resolve:1. Gracefully shut down the SQL Server service, if it is a cluster, you need to shut down the cluster role first to prevent failover, and then shut d
1, open the "Start" menu, click the "Run" button
2, in the pop-up window input "CMD", and then determine or press ENTER.
3, in the command window input "wmicmemphysical get Maxcapacity" and then hit the ENTER key.
4, then the computer will give a string in kilobytes as the number of units. We're going to convert this number to our usual GB unit.
The conversion method is: "The number that comes out/(divided by) 1024/(divided by) 1024"
Figure: My computer gets the number
" option is the maximum number of concurrent connections. The default value is 1024. I have set 256 here, which is based on the load of your server,-P is the pid file for saving Memcache. Here I am saving it in/tmp/memcached. pidMemcache server security:The Memcache server directly performs operations after being connected through the client without any verification process. In this way, it is dangerous to directly expose the server to the Internet, i
At the start---run Place input cmd (or press and hold the Winkdy+r key to enter CMD), open the Command window, enter WMIC memphysical get maxcapacity and enter, and the resulting number is in kilobytes, We divide the obtained number by 1024 divided by 1024, that is, about 1 million, such as the 16777216 K bytes, then divided by about 1 million, probably support 16G of memory, this refers to the physical memory
#include #include unsigned int maxnum = 0;int main (){unsigned int blocksize[3]={1024*1024,1024,1};int i,count;for (i = 0; i {for (count=1;; count++){void* Pmalloc = malloc (Maxnum + blocksize[i] * count);if (Pmalloc){Maxnum = Maxnum + blocksize[i] * count;Free (PMALLOC);//Why do you want to release it here??? Pmalloc is a null pointer.}Else{Free (PMALLOC);//Why not release the memory here??? Break}}}printf ("Maxium malloc size is%u bytes\n", maxnum);
Method one, using tools
See the motherboard model method is also relatively simple, we can use the hardware detection tools such as Lu, quickly learned, as shown in the following figure.
Method Two,
First, open the computer, and then open the "Run" from the Start menu, you can also use the "Win + R" combination of shortcut keys open, and then open the following type: cmd, finished press Enter or "OK" to enter, as shown in the following figure.
Second, in the Open cmd comman
