I am trying to run a process for every 2 min. Though manually job is running, if I create crontab entry it is not running.Entry is as below

2 * * * * /usr/ > /tmp/otpt

If I try to give as */2 * * * * , it is giving error as "Failed to create entry"

How to create an entry which should run for every 2 min , in Solaris-10?

The cron tab format is as folllows.
m(0-59) h(0-23) dom(1-31) m(1-12) dow(0-6) command

And the format you are following is valid for a cron that is supposed to run every 2 minute.

for creating a cron you can use
crontab -e
which I am pretty sure you know.

Your prob may be caused due to some problem in cron. Try restarting the cron once using

svcadm restart svc:/system/cron

Let me know if this information helped you.

Hi Harsha,
I executed the above command and tested the crontab entry. but it is not working...My job is not starting at all :-( But it is running properly if I give it for every minute( * * * * * <path>)
I am very much confused...Is there any other way ????

2 * * * * wont execute the cron for every 2 minutes. It executes the cron 2 minute after an hour. That is why the cron is not running when you use 2 * * * *. The time to run the cron was not achieved there.

using */2 * * * * should solve the problem as this means every 2 minute. But since you said you are having problem with this why dont you try another method wich is rather tedious.
