Symptoms

As per <Note 975448.1> "For the database ADR, auto purge job, implemented as an mmon slave task , purges the expired data from ADR once in 7 days."
If we change the longop_policy and shortop_policy to 24(one day), is there a way to control the MMON slave task frequency to work on a daily basis instead of once every 7 days?
