To automate the exporting of an Oracle table or view, you can use Oracle's Data Pump utility or use a database scheduling tool like Oracle Scheduler to schedule regular exports.


Here are the steps to automate exporting of an Oracle table or view using Oracle's Data Pump utility:

  1. Create a directory in the Oracle database server where the export file will be stored:
1
CREATE DIRECTORY export_dir AS '/path/to/export/directory';


  1. Create a parameter file with the necessary export parameters. For example, you can create a file named export_param.par with the following contents:
1
2
3
4
DIRECTORY=export_dir
DUMPFILE=export_data.dmp
LOGFILE=export_data.log
TABLES=your_table_name


  1. Run the Data Pump export command to export the table using the parameter file:
1
expdp username/password@db_instance parfile=export_param.par


  1. You can create a shell script to automate the export process by putting the above command in a script file and scheduling it to run at specified intervals using tools like cron or Oracle Scheduler.


Alternatively, you can use Oracle Scheduler to schedule regular exports of a table or view. Here are the steps to do this:

  1. Create a new job that will run the Data Pump export command:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
BEGIN
  DBMS_SCHEDULER.create_job(
    job_name        => 'export_job',
    job_type        => 'EXECUTABLE',
    job_action      => 'expdp username/password@db_instance parfile=export_param.par',
    start_date      => SYSTIMESTAMP,
    repeat_interval => 'FREQ=DAILY;BYHOUR=0;BYMINUTE=0;BYSECOND=0',
    enabled         => TRUE
  );
END;
/


  1. You can modify the repeat_interval parameter to specify the frequency at which the export job should run (e.g. daily, weekly, etc.).
  2. Check the status of the job using the following query:
1
SELECT job_name, enabled, state FROM dba_scheduler_jobs WHERE job_name = 'export_job';


By following these steps, you can automate the exporting of an Oracle table or view using Data Pump or Oracle Scheduler.
