If as an Oracle  DBA you want to  generate a file within oracle and ftp it to an ftp server using an oracle scheduler_job .You probably might run into an error like this below

ORA-27369: job of type EXECUTABLE failed with exit code: Permission denied

The solution is easy.

• On the unix  oracle server run the following as oracle

          ls -l  $ORACLE_HOME/rdbms/admin/externaljob.ora

          The result should return something similar to this depending on your file tree layout

          –rw-r—– 1 root oinstall 1536 Apr 16 17:23 /u01/app/oracle/product/11.2-EE/rdbms/admin/externaljob.ora

• As you can see the file by default is read only for oracle,so let’s sudo su – and edit it

          sudo su –

          vi  /u01/app/oracle/product/11.2-EE/rdbms/admin/externaljob.ora

           change the run_user from nobody to oracle and change the run_group from nobody to oinstall as show below and save it

           run_user = oracle
           run_group = oinstall

•            Then you are done.The job should run now
