Auditing on Oracle Database in a Nutshell (11gR2)

In an Oracle Database we can mention following auditing types:

Mandatory Auditing
Standard Auditing
Fine-Grained Auditing
SYS Auditing

Mandatory Auditing causes database start-up/shut-down and SYSDBA-SYSOPER login logout information to be written into AUDIT_FILE_DEST. This auditing cannot be turned off and it's always written into operating system directory specified with

Oracle Goldengate 12c on DBFS for RAC and Exadata

Let us take a look at the process of configuring Goldengate 12c to work in an Oracle 12c Grid Infrastructure RAC or Exadata environment using DBFS on Linux x86-64.

Simply put the Oracle Database File System (DBFS) is a standard file system interface on top of files and directories that are stored in database tables as LOBs.

In one of my earlier posts we had seen how we can configure Goldengate in an Oracle 11gR2 RAC environment using ACFS as the shared location.


One use for the addition of PL/SQL functions in the WITH clause is to get the HIGH_VALUE of a partition in a usable column format.

Parallel Execution -- 5b Parallel INSERT Execution Plan

As noted in my previous post, Oracle does NOT enable Parallel DML by default.  You need to explicitly enable it with ALTER SESSION ENABLE PARALLEL DML.

Can you use the Execution Plan of an INSERT statement to identify if the INSERT was executed in Parallel ?

Here's a brief demonstration :

Adding Vip Address and Goldengate to Grid Infra structure

Earlier this week preparations have been started to add  the Goldengate software to the Grid  infrastructure of on  the Billing environment on production. As part of that scenario   I also had to add a Vip address  that is to be used by the Goldengate  Software  as part of high(er) availability. In my concept  Goldengate Daemons are  running on on Node only  by default.

Keeping track of Oracle licenses with OEM12c – reports

Wouldn’t be nice to get regularly informed how (in)compliant you are with Oracle licenses in an easy – centralized – way, and therefore not have to worry about visits of Oracle’s LMS – License Management Services? I think that would be nice for the most of us. Running LMS-scripts on the target databases, hosts and middleware is for now the most thorough way to get informed about possible incompliancy. Or in some cased,  using some clever – but informal and mostly incomplete – scripting on the OEM-repository.

Vertica Parallel Load

As it is known there are 2 types of storage area in Vertica, WOS and ROS.  Whereas WOS stores data in-memory, ROS stores data in-disk. If you are using COPY command without DIRECT hint, data is first loaded into the WOS area then Tuple Mover moves the WOS data to the ROS area.
