Hi All,
I facing a problem. My application sharing different application in
different db respectively but in one Tomcat.
Sometime the application run until causing other application slow or login
page cannot login ( cannot login mean the login page logging take a lot time
)
I not sure where to troubleshoot it.
Possible:
1. Tomcat setting problem
2. DB structure problem.
Let's me trouble shoot at the tomcat level by increasing the RAM.
My machine running Linux RED HAT 64 bit in
uname -a
Linux 2.6.18-128.el5 #1 SMP Wed Dec 17 11:41:38 EST 2008 x86_64 x86_64
x86_64 GNU/Linux
RAM information
total used free shared buffers cached
Mem: 7977 7929 47 0 44 3461
-/+ buffers/cache: 4422 3554
Swap: 9983 0 9983
Question :
1. How to figure out that I running 32 bit or 64 bit JVM? Which file to look
at?
2. When the system down, I ps aux | grep tomcat
root 6393 9.3 33.0 3997772 2697592 ? Sl 09:28 8:23

org.apache.catalina.startup.Bootstrap start
I a bit confuse in this statement:
-server -Xms2G -Xmx2G -XX:NewSize=512m -XX:MaxNewSize=512m -XX:PermSize=512m
-XX:MaxPermSize=512m
Is it the machine will run in 2G or 512m?
Is it configure wrongly?
