Question

I want to schedule a task on Linux by icrontab, and the task is written in python and have to import cx_Oracle module, so I export ORACLE_HOME and LD_LIBRARY_PATH in .bash_profile, but
it raise the error:

libclntsh.so.11.1: cannot open shared object file.

Since it is ok to run the task by issue the command in shell like:

python a.py  # ok

I change the task in icrontab into a shell script which invoke my Python script, but the exception recurred?

# the shell script scheduled in icrontab
#! bash 
python a.py    

Could you help how to do with it?

Answer 1

Possibly you want to specify PATH — and also ORACLE_HOME and LD_LIBRARY_PATH — so that cron(1) knows where to find binaries.
Read "5 Crontab environment" here.
