Q:

Request for a page or service can take longer than usual to load or respond

It appears that after tomcat has been idle for some time, a first 
request for a page or service can take longer than usual to load or 
respond.
One possible cause that we're working on is that tomcat is unloading 
from memory some cached information, when it has been idle for some 
time, and the delay of this first request is caused by it picking back 
up again.  Is this a likely scenario?  If not, does anyone have any 
suggestions as to what might be happening?  If so, is there a way that I 
can tell tomcat not to clear whatever caches it might have cleared?
Thanks.

A:

It just connection pool test connections issues.I put testOnBorrow parameter the issues is settled.
