List Your Buckets

Use the s3 ls command to list your buckets. Here are some examples of common usage.

The following command lists all buckets.
$ aws s3 ls 2018-12-11 17:08:50 my-bucket 2018-12-14 14:55:44 my-bucket2

The following command lists all objects and folders
aws s3 ls s3://prod-backup/

Enable Oracle 12c Unified Auditing - Pure Mode

Enable Oracle 12c Unified Auditing - Pure Mode

Why we want Pure Mode?
The first is the audit trails are no longer written to their traditional pre-12c audit locations. Auditing is consolidated into the Unified Audit views and stored using Oracle SecureFiles. Oracle Secured Files use a proprietary format which means that Unified Audit logs cannot be viewed using editors such vi and may preclude or affect the use of third party logging solutions such as Splunk or HP ArcSight.

Operations done by SYS are also recorded.

Unified Auditing comes standard with Oracle Enterprise Edition; no additional license is required. It is installed by default, but not fully enabled by default.

Enable Unified Auditing(Pure Mode):

- Stop Application

- Stop Listener

$ lsnrctl stop

- Relink Oracle Home binaries:

SQL> select * from v$option where PARAMETER = 'Unified Auditing';

SQL> shutdown immediate

cd $ORACLE_HOME/rdbms/lib

$ make -f ins_rdbms.mk uniaud_on ioracle

$ lsnrctl start

SQL> startup
