apache2 - Apache with mod_jk Tomcat change DNS Timeout (TTL) -

-

i'm using gslb app geo-distribution , load-balancing.

the app apache --> tomcat througth mod_jk in workers.properties have this:

worker.balancing.port=8009
worker.balancing.host=tomcats8009.gslb.domain.com
worker.balancing.type=ajp13
worker.balancing.socket_timeout=5

if tomcat gslb (tomcats8009.gslb.domain.com) changes ip x.x.x.x ip y.y.y.y, dns resolution seems cached connector mod_jk , request still asking x.x.x.x .

for solving have make "reload" renew resolution y.y.y.y.

any idea? there kind of dns caching in apache or mod_jk connector? solutions?

thanks.
regards.

i dont know if there property @ mod_jk level can set @ jdk level. assuming have sun, parameter "sun.net.inetaddr.ttl" ; setting 0 turn off dns caching. not recommended turning off dns caching affect performance.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
