create 3 his_audits tables in DB for archiving
select * into DB..his_audits_01 from sybsecurity..sysaudits_01 where 1=2 select * into DB..his_audits_02 from sybsecurity..sysaudits_02 where 1=2 select * into DB..his_audits_03 from sybsecurity..sysaudits_03 where 1=2
4. set up a cron job for auto archiving every week
