Subject RE: Problem in shutting down TOMCAT 4.0

add these lines to the catalina.sh script as appropriate


if [ -z "$CATALINA_OPTS" ] ; then
  CATALINA_OPTS="-XdoCloseWithReadPending"
fi


the problem is the httpconnector running on 8080.  If you watch the
catalina.log file (i think this is the right one) you will that when you
start tomcat it creates a parent thread for the http connector and then a
number of child threads. When you shut down tomcat the childs threads die
but the parent thread never does.

The -XdoCloseWithReadPending option to the HP-UX JVM will close a socket
even while a read is pending and thus allow the parent http thread to die.
I am guessing that the parent thread has a good hold on the socket.


Also, something else to keep in mind the JVM will not exit until all threads
die.  We have one application whose that can take up to 3 mins to release it
database connection pool.  Even with the XdoCloseWithReadPending option we
have to wait three mins between restarts.

Hope this helps

Hi all,

I have installed Apache 1.3.3 and TOMCAT 4.0.1 in HPUX 11, with following
JDK version ...
Java(TM) 2 Runtime Environment, Standard Edition (build

PA1.1, mixed mode)

************** Initially when i start TOMCAT, it start without any problem
and i can access it from http://localhost:8080. Below is the start up
message shown **************

First i was quite confuse because I tought i have shut down the TOMCAT
successfully. So i tried to type this in command prompt ::
#ps -ef | grep java
root 18766     1  0 11:26:38 pts/tl    1:27
/opt/java1.3/bin/../bin/PA_RISC/native_threads/java -classpa

so now i type this ::
#kill -9 18766

After i have kill  above process, i can run the startup.sh and boot TOMCAT
successfully.

So from now on, i have to kill the process manually in order to completely
shutdown TOMCAT. shutdown.sh cannot kill the process for me.

How can solve the problem? it so troublesm for me to shutdown TOMCAT if i
have to repeat these steps everytime.
