Q:

Here’s a suggested procedure:


/* Filename on web page: analyze_oem.sp */
CREATE OR REPLACE PROCEDURE analyze_oem IS
    -- Analyze the OEM schema. This job will be submitted
    -- every hour by DBMS_JOB.
  -- cursor to get the current hour
  CURSOR curs_get_hour IS
  SELECT TO_CHAR(SYSDATE,'HH24')
    FROM DUAL;
  v_current_hour NUMBER(2);

  -- option for analyze command
  v_method_opt VARCHAR2(15);

BEGIN
  -- get the current hour
  OPEN curs_get_hour;
  FETCH curs_get_hour INTO v_current_hour;
  CLOSE curs_get_hour;

  -- if the current hour is 1 or 2 inclusive
  -- then perform a complete analysis otherwise just do
  -- it for the indexes

  IF v_current_hour IN (1,2) THEN
    v_method_opt := NULL;
  ELSE
    v_method_opt := 'FOR ALL INDEXES';
  END IF;

  DBMS_UTILITY.ANALYZE_SCHEMA( SCHEMA     => 'OEM',
                               METHOD     => 'COMPUTE',
                               METHOD_OPT => v_method_opt );
END analyze_oem;

This is one possible implementation:

 /* Filename on web page: add_trx.month.sp*/ CREATE OR REPLACE PROCEDURE add_trx_month IS /* || This function adds a new partition to the account_trx || table. It is to be run on the 20th of the month to || create a partition for the next month. */ -- cursor to build date format requirements CURSOR curs_get_date_info IS SELECT '01-' || TO_CHAR(ADD_MONTHS(SYSDATE,1),'MON-YYYY') upper_bound, TO_CHAR(SYSDATE,'YYYYMM') ...
