Thanks Mark for your valuable comments. Based on 3rd question answer (below mail), so does it mean that in tomcat 6.0 i have to use executor to configure minSpareThreads , i cannot define alone with http/ajp connector??
Can someone confirm on this ..pleasee Thanks, Vicky On Nov 4, 2012, at 11:46 PM, Mark Eggers <its_toas...@yahoo.com> wrote: > Comments in line (warning - this is done before coffee): > > On 11/3/2012 8:59 PM, vicky wrote: >> Thanks christopher. >> I am using Probe application for monitoring the Tomcat application , in that >> everything is getting displyed fine except the "Min Spare Threads" & " Max >> Spare thread" >> Ques1 : >> ====== >> Both attributes have the value as Zero.
