Problem with script

grin1dan · #1 (**permalink**) 06-22-2009

Hello All. I have a script that is suppossed to start up a daemon but when executed, simply hangs. Could you please take a look and let me know where the problem might be? TIA

Code:

###################################################################
#
# SCRIPT: dstart3000.sh
# Bring up the Domain
# AUTHOR: 
#
# Description:
# Start the Domain Daemon Server Process on Port 3000
# Execution Syntax:
# ./dstart3000.ksh
# Revision History:
#   2007_09_21  Script created
###################################################################
# Setting up variables
FATAL=255
SUCCESS=0
MAIL_SUBJECT="Domain Daemon Server Process failed to Start"
MAIL_TO="someone@somewhere.com"

program_name=`basename $0 .ksh`
start_time=`date +%y-%m-%d`
#Intializing log file and putting job start time
LOG_FILE="${GM_LOG}/${program_name}.${start_time}.log"
echo "Program ${program_name} started at ${start_time}" > ${LOG_FILE}
echo "Start DomainDaemon process at `date +%Y%m%d_%H%M%S`" >> ${LOG_FILE}
DomainDaemon -port 3000 -start > daemon3000.log 2> daemon3000.err
 if [ $? -ne 0 ]; then
    # The Domain Daemon Start failed ??
    echo ERROR - the Domain Daemon Start Server Failed >> ${LOG_FILE}
    mail -s "${MAIL_SUBJECT}" "${MAIL_TO}" < ${LOG_FILE}
    exit 1
   else
    echo Domain Daemon Started succesfully
 fi
echo  finish Domain Daemon Server Started Succesfully `date +%Y%m%d_%H%M%S` >> ${LOG_FILE}
# Save logfile
# Cleanup and close

Is this the line?:

Code:

DomainDaemon -port 3000 -start > daemon3000.log 2> daemon3000.err

Try running it in the background...

Code:

DomainDaemon -port 3000 -start > daemon3000.log 2> daemon3000.err &

And if it dies when you close your session, run it nohup...

Code:

nohup DomainDaemon -port 3000 -start > daemon3000.log 2> daemon3000.err &

Hope this helps

why don't you add 'set -x' to the script and see where it 'hangs'.

hi, I have tried you script to run and from my point of view the script working fine.

I have changed only the header to #!/bin/bash then I've created a test.log with permission settings 755 and at last I've installed it on my debian OS mailutilities -- that's all!

see my mail

"/var/mail/####": 3 messages 2 unread

That would have been useful info an hour ago

Can you define "hangs"?

What do the .err and .log files tell you (presuming more than the mail does)?

Thanks! for the replies! I need to use Korn on this one so switching to bash is not an option. I am unfamiliar with '-x'. How do I implement this? As for 'hangs', I mean that the job runs but does not finish, i.e. return any messages or get a command prompt back. Also, no .err or .log files ever get created.

From the output of:

Code:

# help set
...
-x  Print commands and their arguments as they are executed.
...

so just put "set -x" at the top of the script before any other commands.

A much more ghetto and tedious way to do it is to add an "echo" command after every command.

Code:

command1
echo 1
command2
echo 2

so when your script "hangs" and all you see on the terminal is "1", then you know that you have a problem with "command2". It's much easier to go with set -x though, I was just trying to illustrate the principle.
