Hi all,

After building my web application we start tomcat service.But its taking too much of time to start. what should be the issue.

my log file entry is this.

july 20, 2010 10:21:27 AM org.apache.catalina.core.StandardEngine start
INFO: Starting Servlet Engine: Apache Tomcat/6.0.26

INFO: Deploying web application directory xxxxx.

thats it. its taking more time to deploy.

What should be the reason.


any suggestions would be really helpful.

Thanks&regards,
Dinesh.

Hi,

Take a look for hints at this page.
Depending on your box memory, you can increase the heap size like:
and see if that helps.
Or consider adding more RAM in your box.

Hi,

Thank you very much for your reply. i have executed export JAVA_OPTS="-Xms512m -Xmx1024m".But Even now tomcat is taking time to start.

I checked whether environment variable is assigned using set command. it assigned like this.

JAVA_OPTS='-Xms512M -Xmx1024M-XX:MaxPermSize=256M'


But i am having the same problem. Any other options please.

Hi bathory,

sorry, its working now. Tomcat starts at normal rate.By setting env variables as you said like this.


JAVA_OPTS='-Xms512M -Xmx2048M-XX:MaxPermSize=512M'

Thank you very much problem solved.

Thanks&regards,
Dinesh.

Hi,

After setting export JAVA_OPTS='-Xms512M -Xmx2048M-XX:MaxPermSize=512M', my tomcat starts and stops with no issues.But i am executing this export command every time when i restart tomcat, as export command set variable temporarily.

so can anyone suggests me, under which file i have to add this entry so that this JAVA_OPTS will remain permanent in my os.

Thanks&regards,
Dinesh.

Hi,

You can add it in the tomcat startup script, or in catalina.sh

Hi,

I have added those entries in /root/.bashrc and /root/.bash_profile. Now env remins permanent for all the sessions of root user.

Thankyou.

Hi,

This is going to work only if you want to login as root and then start tomcat.
If you want tomcat to start on system boot it's not going to work. You have to set JAVA_OPTS as I told you above

Regards

Hi bathory,

Thank you very much for your explanation, actually i was not aware of this, sure i will do this.

Thanks once again.

These are the entries of logfile.

Could not create the Java virtual machine.

What should be the issue. suggestions please.

JAVA_OPTS='-Xms512M -Xmx1024M-XX:MaxPermSize=512M. This is the memory allocated.

What should be the issue.Any suggestions would be really helpful

Thanks in advance,
Dinesh.

Hi,

Looks like you can't allocate 1G for the jvm.
Try some other combination of heap sizes, like: -Xms128m -Xmx512m

Hi bathory,

Thanks&regards,
