Hi,
A couple things.
- 'FREQ=MINUTELY; INTERVAL=1' is actually once every minute, but I think you figured that out.
-'exp system/ali120 FILE=/home/oracle/alifiles/exp1.dmp TABLES=alit1'
There are several problems here. You need to give the full path to exp. exp probably requires several environment variables to be set. You are much better off putting the entire call together with setting of variables in a shell script and calling that.
Only the binary or script should be in the program_action, other elements should be defined as program_arguments ("system/ali120", "FILE=/home/oracle/alifiles/exp1.dmp" "TABLES=alit1")
I am not sure why the job hangs (you can use stop_job to force it to stop). Try calling extjob from the commandline and making sure it returns without any errors.
Hope this helps,
Ravi.
