This could be just new year workload. Or someone is running some new scripts that are consuming LARGE amounts of CPU. The data shows nothing strange in the CPU distribution between servers:
Report: ESAUSP2 <---CPU time--> UserID <(Percent)> T:V /Class Total Virt Rat -------- ----- ----- --- 01/08/14 10:01:00 192.0 183.7 1.0 ***Top User Analysis*** L220P 26.25 25.80 1.0 L216P 24.94 22.64 1.1 L20DP 24.10 23.61 1.0 L217P 23.21 20.79 1.1 L209T 21.59 21.43 1.0 L218P 18.50 18.34 1.0 L20CT 18.03 17.06 1.1 L20BP 7.76 7.62 1.0 L210P 6.89 6.58 1.0 L214P 4.79 4.53 1.1 And from a linux perspective, looking at the cpu by application, oracle is consuming quite a bit - but it really looks like someone is running short perl scripts continuously that are consuming large amounts of data. (*PROD is the group of linux servers making up production, so this is across all servers) . The "init" bucket is a catchall for short term (less than 1 minute) processes who's parent process is init. Thus the high "children" use in INIT for production.

From a couple of days one of our Linux LPAR are continuously using 100% of two cpu. We are on EC12 with z/VM SSI 6.2, two IFL's CPU's, 61440 MB of RAM, 4096 Extended RAM and the guest are running on SLES 11SP2. Do anyone has similar problems or there is a kernel update for this issue.
