DAC: Automate purge of Run History Information

Question

Hello,
I'm trying to find a way to automate the purge of Run History log information.
Is there any command line utility to do this?
Can it be done inside DAC?
The following is the DAC information:
Oracle BI Data Warehouse Administration Console
Dac Build AN 10.1.3.4.1.patch.20110427.0538, Build date: April 27 2011
Management console to setup, configure, load and administer the Oracle Business Analytics Warehouse
Schema version - 34, Index version - 33, Repository version - 6, Seed data version - 9
Thanks in advance,
Daniel

Hi Daniel,
Currently there is no out-of-box automation for the DAC Run detail Purge. How ever we can use the below sql's to delete. I strongly don't recommend this for Production but can be used for non-prod. Assuming dacrep is your DAC repository owner.
--SQL 1 set 1
DELETE FROM dacrep.w_etl_run_sdtl
WHERE run_step_wid NOT IN (
SELECT row_wid
FROM dacrep.w_etl_run_step
WHERE run_wid IN (
SELECT row_wid
FROM dacrep.w_etl_defn_run
WHERE etl_proc_wid IN (
SELECT MAX (etl_proc_wid)
FROM dacrep.w_etl_defn_run)))
-- SQL set 2
DELETE FROM dacrep.w_etl_run_audit
WHERE run_wid NOT IN (
SELECT row_wid
FROM dacrep.w_etl_defn_run
WHERE etl_proc_wid IN (
SELECT MAX (etl_proc_wid)
FROM dacrep.w_etl_defn_run))
-- SQL set 3
DELETE FROM dacrep.w_etl_run_summ
WHERE run_wid NOT IN (
SELECT row_wid
FROM dacrep.w_etl_defn_run
WHERE etl_proc_wid IN (
SELECT MAX (etl_proc_wid)
FROM dacrep.w_etl_defn_run))
-- SQL set 4
DELETE FROM dacrep.w_etl_run_step
WHERE run_wid IN (
SELECT row_wid
FROM dacrep.w_etl_defn_run
WHERE etl_proc_wid NOT IN (
SELECT MAX (etl_proc_wid)
FROM dacrep.w_etl_defn_run))
-- SQL set 5
DELETE FROM dacrep.w_etl_defn_run
WHERE etl_proc_wid NOT IN (SELECT MAX (etl_proc_wid)
FROM dacrep.w_etl_defn_run)
Please let me know if this worked for you.
Regards,
Jay
