java - Ehcache write-behind caching thread-priority -

-

i'm trying use ehcache write-behind caching write batches of transactions database. need write-behind cache dump transactions @ 5 second intervals (or more often).

i must missing something, because try might, won't work. set write-behind caching, , put load onto server. thousands, , hundreds of thousands of transactions later, , after waiting several minutes, there still nothing in database. isn't until shut down load on server cache begins writing database.

is problem thread-priority? there way modify ehcache perform db writes when server under load?

here configuration:

<cache name="server.db.model.request"  maxelementsinmemory="10000"  eternal="false"  timetoidleseconds="5"  timetoliveseconds="5"  overflowtodisk="false"  memorystoreevictionpolicy="fifo">     <cachewriter writemode="write_behind" maxwritedelay="5" ratelimitpersecond="5"      writecoalescing="true" writebatching="true" writebatchsize="5000"      retryattempts="2" retryattemptdelayseconds="10">         <cachewriterfactory class="server.db.util.requestcachewriterfactory"/>      </cachewriter> </cache>

thanks.

hmmm... that's weird. have been doing extensive testing , have never experienced writer thread never getting cpu time. os running ? thread creating cachemanager running @ lower priority ?

also, sorry maybe asking obvious, when "shut down" load mean ? not shutting app (and cachemanager) down ? asking "transaction demarcation happen within writeall/deleteall method, right ?"…

one last remark well, tagged hibernate, didn't configure write-behind on hibernate 2nd level cache right ? that's wrong tag, isn't ?

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,...

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
