One of my Oracle servers became full and I noticed one of my Database consumed over 40Go of logs stored in “../diag/rdbms/db_name” unless the Retention Policy was low…
Here’s how i cleaned this up manually using ADRCI tool in a Command Prompt.
C:\Users\Administrator>adrci ADRCI: Release 22.214.171.124.0 - Production on Mer. Mars 22 09:53:24 2017 Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved. ADR base = "D:\oracle" adrci> show homes ADR Homes: diag\rdbms\db_name\db_name adrci> set home diag\rdbms\db_name\db_name adrci> purge
If needed, you can check the Retention Policy using:
adrci> show control
And change it using (Example. Note it is defined in Hours):
adrci> set control (SHORTP_POLICY = 168) adrci> set control (LONGP_POLICY = 720)
LONGP_POLICY (long term) defaults to 365 days and relates to things like Incidents and Health Monitor warnings.
SHORTP_POLICY (short term) defaults to 30 days and relates to things like trace and core dump files
