sql loader won't run from php... Why?

[wxdqz]

Hi there folks, I was wondering if you could help me. I wrote a shell script that called the oralcle sqlloader to load some data into our database. When I run the shell script from the command line everything works perfectly. When I call the script from PHP, the script runs, but the loader portion of it does nothing. The log files indicate that it hasn't even been run. I checked to make sure the script is being called ok, and it is. Both the shell script and the php script have the same owner, so it is not a rights issue.

I also tried making the call to the sqlloader from right inside PHP with the exec command. Still nothing, but PHP reported no errors.

Any ideas?

Thanks

Dave
