yogesh,

how r u adding script to cron here?
what is there is cron.allow file ?
you need to add user id in cron.allow first
switch to that user
set editor to vi (export EDITOR=vi)
run crontab -e
update/save and close

if cron.allow exists and you dont have entry in cron.allow while cron.deny is empy cron job will not run.

if cron.allow exists then you better add userid into this file using vi

also check if cron process is active

ps -ef|grep cron |grep -v grep

hi yogesh,

if your cronn.deny is empty and cron.allow is does not exist, In this
case, all users of the system are granted cron access.so be careful of this situation.

>>.I schedule it but it is not running

try stopping the cron damaen and then start it again,

/usr/sbin/cron stop
/usr/sbin/cron start

check then by ps -ef|grep con

>but /usr/sbin/cron start is not available.

As documented in cron(1M), that should be: /sbin/init.d/cron

check with

ps -ef | grep cron

/sbin/init.d/cron status
/sbin/init.d/cron stop
/sbin/init.d/cron start

Check for onwer of the cron job in cron.allow file

You can edit crontab

crontab -e

Thanks

SKR

>In sbin /init.d is not available.

What does this show:
ll /sbin/init.d/cron
ls /sbin/init.d/ | wc

This file is part of:
OS-Core.UX-CORE: /sbin/init.d/cron
PHCO_32371.UX-CORE: /sbin/init.d/cron

Is this actually HP-UX, then? Or is it some other variety of Unix/Linux?

Do you have anything in /etc/init.d perhaps?

# ls -l /etc/init.d/cron*

Re: cronjob is not running

yogesh kumar_2 — Fri, 29 Aug 2008 12:46:00 GMT

hi

i have /etc/init.d/crond

Re: cronjob is not running

Dennis Handly — Fri, 29 Aug 2008 12:54:05 GMT

As mentioned by Patrick, what does "uname -a" show?
You are either on some foreign devil OS, or on 9.x?

Re: cronjob is not running

Patrick Wallek — Fri, 29 Aug 2008 13:47:32 GMT

OK, then try:

# /etc/init.d/crond start

If it says something about already started, then try:

# /etc/init.d/crond stop

# ps -ef |grep cron
If there are still cron processes, kill them.

# /etc/init.d/crond start

If this happens to be a LINUX server of some variety, then you can try:

# rccrond start

or if cron is already running

# rccrond restart

Its a LINUX m/c

Re: cronjob is not running

Patrick Wallek — Fri, 29 Aug 2008 14:05:27 GMT

That would have good to know from the beginning.

Since you didn't mention that to start with everyone here kind of assumed it was HP-UX, since your question was posted in the HP-UX forum.

Since it is Linux, see my post above and see if any of it works.

hi how to run its saying wrong command.
pls tell me in stepwise.

Re: cronjob is not running

Patrick Wallek — Fri, 29 Aug 2008 14:13:13 GMT

Without seeing EXACTLY what you are doing, it is hard to tell.

WHAT is saying "wrong command"? Can you cut-and-paste the EXACT commands and errors you are getting?

Re: cronjob is not running

Deepak Kr — Fri, 29 Aug 2008 22:43:45 GMT

Yogesh,

First things is that you should always tell OS coorectly before you give other details as this ease the work here to help you further.

Never mind, can you provide us following:

#uname -a
#ls -ltr /etc/init.d/*cron*

To manage crond daemon in Linux, we can make use of â serviceâ command.

To check the status of crond daemon:

service crond status

To stop and terminate crond process:

service crond stop

To start and run crond daemon:

service crond start

To restart crond service:

service crond restart

also:
To restart the cron service, use:
# /etc/init.d/crond restart
