Hi,

I am also facing the same problem as in http://www.linuxquestions.org/questi...om-cron-690467

00 06 * * * . /oracle/scripts/test.sh </dev/null >/dev/null 2>/dev/null

it will execute successfully.

when i convert it into binary file:-

00 06 * * * . /oracle/scripts/test </dev/null >/dev/null 2>/dev/null

That was quite a while ago... let's see:
Have you read through the thread and followed the advise there already?
Will the binary execute OK from the commandline?
Have you looked through the logs to see what they say?
If you don't suppress the output messages, what do they say?

Thanks for the quick reply.

yes, binary file execute very well as "./oracle/scripts/test"
cron user is oracle.
all the environment variables are ok as "/oracle/scripts/test.sh" run through crontab very well.
Logs for failure that i know is at "/var/adm/cron/log" where is can see "FAILED" or "SUCCESSFUL".
and its SUCCESSFUL for test.sh but FAILED for test(binary file)
I don't know any other Logs of cron jobs.

Please suggest.

/var/adm/cron/log

Is this Solaris?

You piped the outputs in the execute command - you could try piping them to a text file and then reading the file?
You should check your loglevel for cron - set it to 15.

Did you check the other suggestions in the rest of this thread?

What is the output of:
ls /oracle/scripts/test -l

Note: from cron(8)
cron logs its action to the syslog facility 'cron', and logging may be controlled using the standard syslogd(8) facility.

[aside: I don't have a log at /var/adm/cron/log ... so, supplimental to chrism01's question: what is the system?]

I notice that in your original crontab entry

Code:

00 06 * * * . /oracle/scripts/test.sh </dev/null >/dev/null 2>/dev/null

the script is not executed, but "sourced" using the . (dot) command. Then it appers you retained the same syntax after having converted the script to binary:

Code:

00 06 * * * . /oracle/scripts/test </dev/null >/dev/null 2>/dev/null

Is this a typo in your post or might it be the reason for which the cron job fails? If this is the case, what happens if you remove the dot from the crontab entry? Does it work?
