Creating a Job to execute a .sh file

Question

Hi,
I have an important issue creating a Job to execute a .sh file,
the .sh (start_execution.sh) contains a lot of random calls like this:
#!/bin/bash
. /home/crm/.bash_profile
. /home/crm/argentina/crm/crmdw/clusters/mt/mt_pull_push/start.sh
. /home/crm/argentina/crm/crmdw/clusters/ota/ota/start.sh
sqlplus dware/argu01@crmarg @/home/crm/crmdw/AR/exec_dw.sql "MT"
sqlplus dware/argu01@crmarg @/home/crm/crmdw/AR/exec_dw.sql "OTA"
sqlplus dware/argu01@crmarg @/home/crm/crmdw/AR/exec_dm.sql "DAILY_DOWNLOADS"then creating the next job
Begin
dbms_scheduler.create_job
(job_name=>'job_AR',
job_action=>'/home/crm/crmdw/AR/start_execution.sh',
number_of_arguments=>1,
job_type=>'executable',
start_date => SYSDATE,
repeat_interval => 'FREQ=MINUTELY; INTERVAL=20',
enabled=>false,
auto_drop => TRUE,
comments=> 'Run shell-script test_dbms_scheduler.sh');
dbms_scheduler.set_job_argument_value(job_name =>'job_AR', argument_position => 1, argument_value => 'Parameter passed from Oracle to Unix');
dbms_scheduler.enable('job_AR');
end;
/the system executes all process at the same time instead of one to one,
Is necessary the system executes one to one becouse is a Hierarchy of process with
corresponding dependencies.
what could I do to resolve the issue??
any ideas??
Thanks in advanced...

Answer 1

the problem is the content of the .sh file(start_execution.sh) is generated ramdomly and automatically and the code is :
