This task designed to be run semi-annually to prevent table W005_PROCESS_LOG from being overflowed and throwing of out of space error(OracleException (0x80004005): ORA-01652: unable to extend temp segment by 128 in tablespace TEMP)

The core of the process sits in the Stored Procedure CAMIS.SP_BACKUP_W005_PROCESS_LOG

The purpose of the procedure is to:

Rename (ALTER) the current W005_PROCESS_LOG table into the archived versions using patterns such as
Image Added
Cascade changes such triggers replacements, indexes, synonyms accordingly
Send email upon completion using parameters from the table DA004_SETTING
1. Field TO: is taken from “wa005_process_log table half-yearly backup” => DLOTTAFCCCDBASUPPORT@tc.gc.ca;
2. Field FROM: “ERROR_MAIL_FROM“ => DLOTTAFCCCDBASUPPORT@tc.gc.ca;
3. Body of the email constructed accordingly:
  1. Success message with timestamp
  2. Error message with the body of the error and timestamp
The Stored procedure is using another store procedure - CAMIS_DUI.sp_email_notify(…) to send emails

To run CAMIS.SP_BACKUP_W005_PROCESS_LOG procedure Oracle is using Scheduler Program CAMIS.PROG_RUN_SP_BACKUP_W005

Code Block

BEGIN
  DBMS_SCHEDULER.DROP_PROGRAM
    (program_name          => 'CAMIS.PROG_RUN_SP_BACKUP_W005');
END;
/

BEGIN
  SYS.DBMS_SCHEDULER.CREATE_PROGRAM

  SYS.DBMS_SCHEDULER.ENABLE
    (name                  => 'CAMIS.PROG_RUN_SP_BACKUP_W005');

The Scheduler Program is connected to Scheduler Job CAMIS.JOB_RUN_SP_BACKUP_W005

Code Block

BEGIN
  SYS.DBMS_SCHEDULER.DROP_JOB
    (job_name  => 'CAMIS.JOB_RUN_SP_BACKUP_W005');

And the Scheduler Job is dependent on Scheduler Schedule CAMIS.SCHED_HALF_YEARLY

Code Block

BEGIN
  SYS.DBMS_SCHEDULER.DROP_SCHEDULE
    (schedule_name  => 'CAMIS.SCHED_HALF_YEARLY');
END;
/

BEGIN
  SYS.DBMS_SCHEDULER.CREATE_SCHEDULE

     ,repeat_interval  => 'FREQ=monthly; INTERVAL=6; BYDAY=1TUE;BYHOUR=00; BYMINUTE=0; BYSECOND=30'
     ,end_date         => NULL
     ,comments         => 'Running the first Tuesday, every six months at 0000:00:30hrs (30 sec after midnight)'
