Re: Graal and Tomcat Native

2019-07-22 Thread Giorgio Zoppi 
Just a comment the function choosenum is not safe, the rand() is not a good
PRG, i would use if it is possible arc4random in bsd/linux.
Best Regards,
Giorgio.

Re: [Tomcat Wiki] Update of TomcatGridDesign by theimpaler

2015-06-22 Thread Giorgio Zoppi 
Hello all,
it is my first post. Interested in the community. Looks like too complex.
Which is the rational of tomcat grid? which uses cases should it cover?
Best Regards,
Giorgio

 Dear Wiki user,

 You have subscribed to a wiki page or wiki category on Tomcat Wiki for
 change notification.

 The TomcatGridDesign page has been changed by theimpaler:
 https://wiki.apache.org/tomcat/TomcatGridDesign?action=diffrev1=1rev2=2


   Considering the profiles are usually shared between instances (the
 customer facing profiles are probably identical for all customer facing
 instances), they are defined only once. Each instance references them, so
 they can be easily tuned on a single place instead of being copied all over
 the place.
