In current setting, we have shortp_policy and longp_policy both values are consider in hours to purge the trace or log files. Example Shortp_policy = 72 hours means 3 days or Longp_policy = 8760 hours means 365 days (1 year)

Shortp_policy used for purge the short life needed trace or logs like TRACE, CDUMP, UTSCDMP etc.

Longp_policy used for purge long life needed trace or logs file like alert, incident, sWeep, stage etc.

Change the value of shortp_policy and longp_policy:

-- Set for shortp_policy for 30 days
adrci> SET CONTROL (SHORTP_POLICY = 720 )

--Set longp_policy for 90 days
adrci> SET CONTROL (LONGP_POLICY = 2160 )

--Check changed values:
adrci> show control
