Re: Why cannot I put JSVC into a shell script to run

Are you saying that when you run a command from console it works but when you put it into a shell script and try and run the script it doesnt work ?

Are you using the same command from console , did you try and do a ps to see if tomcat has started/not started ?
Putting the entire command on one line shouldnt be an issue .

One thing is that I make all these strings into one single line in the
startTomcat.sh, will this have any effect?

./bin/jsvc -jvm

Do I need to setup the environment variable? However I can run the command from
the console without the environment setup either.

Pascal:

Thanks for the detailed explanation,

The procedure I used to launch jsvc

Login in SERVER using root account through SSH.

Go to TOMCAT directory,

Run startTomcat.sh, nothing happened.

Then run command cat startTomcat.sh and copy/paste the command to the console,
hit enter.

Tocmat started after verifying the netstat -nlp | grep jsvc


I setup all the environment variable like inside Catalina.sh
By adding 4 echo in my startTomcat.sh

"
echo "JAVA_HOME: $JAVA_HOME"
echo "CATALINA_HOME: $CATALINA_HOME"
echo "CATALINA_BASE: $CATALINA_BASE"
echo "CATALINA_TMPDIR: $CATALINA_TMPDIR"

Rather use lsof -i instead of netstat + having to grep the output:

if lsof -i:8080 &>/dev/null; then
  # something is listening on 8080
else
  # nothing is listening on 8080
fi


Another approach is to use netcat in "zero I/O mode" to make a TCP
connect on the port:

if netcat -n -w 1 -z localhost 8080; then
  # something responds to connect on 8080
else
  # nothing responds to connect on 8080
fi

N.B.:
 -n is to avoid host and protocol name lookups
 -w 1 is to set the timeout for the connect to 1 second
 -z is for "zero I/O mode" -- i.e. just connect() and close

Just a wild guess: what about your JAVA_HOME, JRE_HOME and other
environment variables that affect Tomcat ?

Are you starting that shell script from the same environment as when
you do it with the command, directly ?
Same environment means: same user, also from an interactive shell, etc...

If, for example, that shell script is being started by init as root,
you will end up having a totally different environment as when you log
in into an interactive shell.

bash -x ./my_script.sh

See above.

Personally, I always setup the full environment (well, at least the
environment variables that affect Tomcat) in bin/setenv.sh
If that file exists, it will automatically be sourced by catalina.sh

That's where you should do your environment settings, especially
JAVA_HOME and JRE_HOME.
Do not rely on the environment as it is setup by an interactive login
(e.g. ~/.profile or ~/.bashrc)

e.g.
---8<-------------------------------
JAVA_HOME=/usr/java/jdk1.5.0
JRE_HOME=$JAVA_HOME
JAVA_OPTS="-Xms128m -Xmx128m"
PATH=$JAVA_HOME/bin:$PATH
export JAVA_HOME JRE_HOME
---8<-------------------------------
