Operating Systems AIX What happened if CPU utilization is near to 100 % in AIX 6.1? Post 302817689 by rbatte1 on Thursday 6th of June 2013 10:16:51 AM

So, is this IBM HA configured as a two-node Active-Active cluster?

All that would likely happen from the OS point of view is that you will be CPU bound and processing will slow a little. The end-user symptoms you may see though may be worse. Does your application have a time-out in it? If the processing does not complete quite as quickly, will that be a problem? Is this a time critical application, e.g. financial transactions critical to the sequence or millisecond for real-time trading perhaps?


The worry will be if a time-out occurs although a background query is still processing. What you tend to get then is users re-submitting. Eventually you will be flooded by user requests and the CPU will never go idle for the rest of the day.


You need to answer these questions for yourself to see if you have adequate provision.

NAME
cpu - connection to cpu server SYNOPSIS
cpu [ -h server ] [ -c cmd args ... ] DESCRIPTION
Cpu starts an rc(1) running on the server machine, or the machine named in the $cpu environment variable if there is no -h option. Rc's standard input, output, and error files will be /dev/cons in the name space where the cpu command was invoked. Normally, cpu is run in an 81/2(1) window on a terminal, so rc output goes to that window, and input comes from the keyboard when that window is current. Rc's cur- rent directory is the working directory of the cpu command itself. The name space for the new rc is an analogue of the name space where the cpu command was invoked: it is the same except for architecture- dependent bindings such as /bin and the use of fast paths to file servers, if available. If a -c argument is present, the remainder of the command line is executed by rc on the server, and then cpu exits. The name space is built by running /usr/$user/lib/profile with the root of the invoking name space bound to /mnt/term. The service envi- ronment variable is set to cpu; the cputype and objtype environment variables reflect the server's architecture. FILES
The name space of the terminal side of the cpu command is mounted on the CPU side on directory /mnt/term. SOURCE
/sys/src/cmd/cpu.c SEE ALSO
rc(1), 81/2(1) BUGS
Binds and mounts done after the terminal lib/profile is run are not reflected in the new name space. CPU(1)
