Hi guys and gals,

I have this script that run perfectly when executed manually. If I place it in a cron to run on a schedule, it fails. Error is:

Code:

exec(): 0509-036 Cannot load program /usr/local/bin/getlogical because of the following errors:
        0509-150   Dependent module libclntsh.a(shr.o) could not be loaded.
        0509-022 Cannot load module libclntsh.a(shr.o).
        0509-026 System error: A file or directory in the path name does not exist.

I'm using absolute paths in the crontab. Why would it run fine when executed manually and fail in a cron?

Dear friend ,

pls give details abt cron entry..

That would happen if you use different environments. Make sure the cronjob is run as the same user that can run the script from commandline. If you want to run the script as a different user from cron you either need to source the environment* of the user who can run the script or adapt the cron user's environment to the commandline user's.

* Lookup the dot command

Here is the entry in fron the crontab

Code:

$ crontab -l
57 8 * * * /path/to/script.sh > /path/to/script.sh_01162010.log 2>&1

I am running the script as the same user.

Hi bbbngowc,
When you exucute something from cron you don't have the same evironment setup as you do when you execute it from the command line when you are logged in. For instance I have a command that I can execute from the command line like this:

Code:

jqsubmit -jlawis lawadm spendcompa

I can do that by itself because when I log in there is a command in my profile (located in my home directory) that gets executed to set up the environment needed to execute it. The command is:

Code:

 . cv lawprod

Now to execute the first command from cron I have to set up a file combining the two commands like this:

Code:

. cv lawprod
jqsubmit -jlawis lawadm spendcompa

I then execute the above file from cron. I believe that is what shockneck was trying to explain.

Is there a way I can make my script environment independent? So it'll run regardless of the user and regardless of the cron or otherwise?

Yes, pretty simple actually. Just set up the environment you need yourself, at the beginning of the script. If you need the same for more than one script, put the set-up into a separate script & source it at the beginning.
