sql - MAXDOP is set to 0, however, all transactions run in serial -

-

the server setting maxdop set 0 , threshold default of 5.

all transactions run against server run in serial , not against multiple cores/cpus (virtual machine , has 8 cpus).

server windows server 2008 r2 enterprise x64 , sql server 2008 r2 enterprise x64.

there "default" , "internal" workload group on machine both resource governors not enabled , disabled, have maxdop setting of 0.

i've confirmed sql server has cpu affinity across cores/cpus.

i'm kind of lost why server refuses run transactions in parallel opposed other machines @ location. came in noticing many of servers here had long cxpacket wait times , many processes causing wasted cpu overhead. dba said after reading evaluation there nothing wrong maxdop 0 , threshold of 5 because xxxx server never runs in parallel say.

i believe evaluation of site still correct, darn server debunking evaluation.

i open suggestions why server not configured , should run in parallel doesn't.

i've plotted data points , fitted exponential curve between them using 'fit' in matlab. problem fit-function got fitted line wanted plot, markers on top of regular markers. solved problem plotting wanted markers on top of unwanted couldn't seen. problem. when want show legends dots in there. how can remove markers legend without removing fitted line since both of them hidden inside fit-function? can stop 'fit' plotting unwanted markers? so, want remove blue dot called 'hoff' in picture below. you can leave out legend-entries manually leaving out handles of lines, dont want in legend. try this: %if plot something, want showing in legend, save handle: h_line = plot(x,y) %you dont want show line? dont anything, plot it: plot(mymarker) %then set legend-> can add text legend-entries %a cell-array containing strings want show up: legend([h_line another_line],{'text1' 'text2'}) with example (see comments) came solution:

java - Why does my date parsing return a weird date? -

-
here code using: string string = "08/07/2013".replace('/', '-'); date date = new simpledateformat("yyyy-mm-dd").parse(string); why date return: "wen jan 3 00:00:00 est 14"? not @ date format told use. edit: need format because database using requires format. the format use parse date string, not match it. using yyyy 08 . use following format: new simpledateformat("dd-mm-yyyy") and why @ replacing / - ? can build pattern original string only: string string = "08/07/2013" date date = new simpledateformat("dd/mm/yyyy").parse(string); and if want date string in yyyy-mm-dd format, can format date using dateformat#format(date) method: string formatteddate = new simpledateformat("yyyy-mm-dd").format(date); see also: change date format in java string simpledateformat java doc
