Tomcat 6 on RHEL3
Dear All,
I have an issue with tomcat 6 which is deployed under RHEL3 with JDK5, the problem is tomcat is taking hell lot of time in deploying the war files when started.
It's so busy that not responding back with home page also, what could be the problem ?

Ningappa Koneri

Could also be happening if the machine is otherwise idle and various bits of the JVM or your webapps are waiting for /dev/random to have enough bytes to work with. Look in your JRE's lib/security/java.security file to see if the JVM is set to use /dev/random instead of /dev/urandom, and check your webapp code.
Take a thread dump during the startup delay and see what's going on.

What's the spec of the machine on which you're running Tomcat? How much
heap and permspace have you allocated to the Java virtual machine in which
Tomcat is running, and how much memory is it using? (top will tell you how
much memory it's using; it will be more than heap+permspace due to other
operating system structures)
Is the machine busy during all this time? If so, what is the limiting
factor - disk i/o, memory or CPU? Run top to get an idea of CPU usage,
vmstat (I use "vmstat 5" until I have a better idea) to get an idea of disk
i/o.
How large is the war file? If you unzip the war files (a war file is just a
zip file with a different extension) on the same machine, how long does it
take?

Tomcat doesn't compile all of your JSPs at start up. The delay is more
likely to be occurring for another reason.
You can precompile the JSPs during your build process, using the Jasper
Ant task. See the docs for how to do this.

Hi Gurkan,
I guess ur right, as tomcat is trying to deploy the applications it's taking lot of time because of compilation only I guess. One more thing is why home page is not coming? The http request bytes got stuck in recv queue of tomcat port. How to get rid of this situation ? can't v disable the compiling of jsp files at startup ?
It took abt 1328 seconds to startup the applications. Please help.
INFO: Server startup in 1327549 ms :(

Please look at logs file under directory logs. Maybe your JSP files are so
complicated and takes time while Tomcat compiles them on the first time.
