cluster computing - jboss clustering GMS, join -

-

i have jboss 5.1.0.

we have configured jboss somehow using clustering, in fact not use clustering while developing or testing. in order launch project have type following:

./run.sh -c -g uniqueclustername -b 0.0.0.0 -djboss.messaging.serverpeerid=1 -djboss.service.binding.set=ports-01

but while jboss starting able see in console:

17:24:45,149 warn [gms] join(172.24.224.7:60519) sent 172.24.224.2:61247 timed out (after 3000 ms), retrying 17:24:48,170 warn [gms] join(172.24.224.7:60519) sent 172.24.224.2:61247 timed out (after 3000 ms), retrying 17:24:51,172 warn [gms] join(172.24.224.7:60519)

here 172.24.224.7 local ip though 172.24.224.2 other ip of other developer in our room (and jboss there stoped).

so, tries join other node or something. (i'm not familiar how jboss acts in clusters). , result application not starting.

what may problem in? how avoid joining ?

you can fix specifying 

-djgroups.udp.ip_ttl=0

in startup. sets ip time-to-live on jgroups packets zero, never anywhere, , cluster never form. use in dev here stop various developer machines forming cluster. there's no need specify unique cluster name.

i'm assuming need clustering in production, right? use default configuration instead of all? remove clustering stuff altogether.

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,
