Edouard,

You need look at the individual threads associated with the job. Tomcat
starts with a thread pool that it uses to process requests. The main
thread can be in *TIMW while the worker threads are actually doing
something. Look at the job using WRKJOB and enter option 20. That should
show the individual threads along with their priority, etc. If you hit
F5 a few times you will probably see a thread that is consuming CPU. If
you put a 10 on that thread, you will see the stack, which is sometimes
helpful.

Hi all, Im running Tomcat on the 400, everithing run well, my only
problem 
is the job take 56% of the processor on the status TIMW (When nothing 
accessing tomcat)

here is the CL to start the job:

SBMJOB     CMD(QSH CMD('/TOMCAT400/BIN/CATALINA400.SH')) + 
             JOB(CATALINA) JOBQ(QSYSNOMAX) + 
             CPYENVVAR(*YES) ALWMLTTHD(*YES) 

the script:

# shell script to run Tomcat 4.0 and earlier
# SBMJOB CMD(QSH CMD('tomcat400/bin/catalina400.sh')) JOB(catalina)

# To provide multiple instances of Tomcat, development, test, and 
production,
# modify this script to set CATALINA_BASE to a directory containing the

conf, log,
# and work directories. Copy the conf directory found in CATALINA_HOME
to 
the new
# conf directory in CATALINA_BASE. I set CATALINA_BASE to
$home/tomcat400
# if it exists. Scan for and replace the following original ports in
the 
server.xml
# file found in the conf directory. I prepend a 1-6 allowing for 7
total 
servers.
#
# orig    new
# 8005 | x8005 | Shutdown
# 8080 | x8080 | Non-SSL HTTP
# 8443 | x8443 | Redirect port - Used / SSL HTTP Connector - Not used
# 8009 |       | AJP Connector
# 8081 |       | Proxied HTTP
# 8082 |       | Test HTTP
# 1521 |       | Oracle
# 8008 | x8008 | Warp Connector


# Set job priority to standard for interactive (interactive - 6) by
using
# the interactive priority - 6, the helper threads that respond to 
requests
# will be running at the same priority as interactive jobs.

export COMMAND='chgjob job('$JOBNAME') runpty(20)'
system $COMMAND

export QIBM_MULTI_THREADED=Y
export -s JAVA_HOME=/QIBM/ProdData/Java400/jdk13
export -s CATALINA_HOME=/tomcat400

# Set CATALINA_BASE to point to a directory containing conf, work, and

logs
# directories if you want to run multiple instances of Tomcat but share

the
# the same installation found in your CATALINA_HOME directory.
# export -s CATALINA_BASE=$HOME/$CATALINA_HOME
export -s CATALINA_BASE=$CATALINA_HOME

# The following line allows you to compile JSP pages
CP=$CATALINA_HOME/bin/bootstrap.jar:/QIBM/ProdData/Java400/jdk13/lib/tools.jar
export -s CLASSPATH=$CP

echo Using Classpath:     $CP
echo Using CATALINA_BASE: $CATALINA_BASE
echo Using CATALINA_HOME: $CATALINA_HOME
echo Using JAVA_HOME:     $JAVA_HOME

# Run tomcat:
#   on releases prior to V5R1 systems add -Djava.version=1.3
#   to debug use -debug -Djava.compiler=NONE 
#   set -Duser.dir appropriately, it becomes the relative base for file

I/O
#   on larger sites, consider upping the memory from 64 to something 
bigger

java -ms64m -Duser.dir="$CATALINA_BASE"
-Dcatalina.base="$CATALINA_BASE" 
-Dcatalina.home="$CATALINA_HOME" org.apache.catalina.startup.Bootstrap

"$@" start

Thanks in advance
