I am back

It's been a very long time not coming here, about 2 years and half ... and I missed it big time.

Now I moved to Oracle Systems (formerly Sun Microsystems) on a role support-programmer mixed, within RPE (Revenue Product Engineering) on the Extra Care team, with focus on Solaris, Engineered Systems with Solaris, ZFS Storage Appliance and Ops Center. I'm very happy since my job is closer to development, something was (more...)

What Is Oracle 12 Unified Auditing? The View UNIFIED_AUDIT_TRAIL with 94 Columns

What is Oracle 12c Unified Auditing? The short answer is the view UNIFED_AUDIT_TRAIL. This view consolidates all logging and auditing information into a single source. Regardless of using either Mixed Mode or Pure Unified Auditing, the SYS.UNIFIED_AUDIT_TRAIL can be used. 

The key column in SYS.UNIFIED_AUDIT_TRAIL is AUDIT_TYPE.  This column shows from which Oracle component the log data originated -

Reminder to myself: turn off felix service urlhandlers in combined BPM & OSB12c installation

Last week I started with creating a few OSB services for my current project, which is in fact a BPM12c project that needs to be interated with database services on an AS400, thus DB2. Firstly I found that when I tried to deploy on a standalone wls domain (created with the qs_config script), it lacks an OSB installation. Whereas the integrated weblogic default domain has one.

But when I try to deploy to a pretty (more...)

Generating a Calendar View of Employee Absence

Baselines und Parsing

Jonathan Lewis weist darauf hin, dass Baselines keine große Hilfe sind, wenn es darum geht, den Aufwand beim Parsen komplexer Join-Operationen zu verringern. In seinem Beispiel führt ein Join von acht Tabellen zur Prüfung von 5040 Join-Reihenfolgen - wobei die Einstellung von _optimizer_max_permutations=2000 offenbar ignoriert wird - und das ändert sich auch dann nicht, wenn eine SQL Plan Baseline für die Query erzeugt wird, weil der Optimizer zunächst versucht, einen besseren Plan zu erzeugen, ehe (more...)

Tableau: Delineate Belgian provinces explained

Tableau Software is a self-service BI-tool that allows data visualisation, meaning that even business users should be able to easily visualise their data (without needing help of IT). You can check out the Tableau website for more information about this great tool.

As you may have already seen in several guides or tutorials, Tableau is able to link certain dimensions like postal code, countries, etc. to a certain geographical area. Unfortunately, most of these (more...)

12.1.0.2 Introduction to Zone Maps Part III (Little By Little)

I’ve previously discussed the new Zone Map database feature and how they work in a similar manner to Exadata Storage indexes. Just like Storage Indexes (and conventional indexes for that manner), they work best when the data is well clustered in relation to the Zone Map or index. By having the data in the table […]

Finding Direct Indexes

If you’re not using Toad DBA Suite, it’s sometimes hard to find solutions. Somebody wanted to know how to find indexes that aren’t that aren’t indirect. Indirect indexes are those created for a primary key because a primary key column or set of columns are both not null and uniquely constrained. You can’t drop a unique index for a primary key without dropping the primary key constraint that indirectly created it.

The following query (more...)

Baselines

I’m not very keen on bending the rules on production systems, I’d prefer to do things that look as if they could have happened in a completely legal fashion, but sometimes it’s necessary to abuse the system and here’s an example to demonstrate the point. I’ve got a simple SQL statement consisting of nothing more than an eight table join where the optimizer (on the various versions I’ve tested, including 12c) examines 5,040 join orders (even though _optimizer_max_permutations (more...)

Oracle Database 12c : EXPAND_SQL_TEXT, APPROX_COUNT_DISTINCT, Session Sequences and Temporary Undo

While I was away on the OTN APAC tour, I wasn’t really able to sink my teeth into anything, so inspired by Connor McDonald‘s session in Perth, I decided to write up a few bits and pieces in my free moments in the hotels and planes (when I had enough elbow room to type).

Here is what I’ve neatened up so far.

OTN APAC 2014 : Summary

As you will have seen from my last post, I’m back in Birmingham after completing the OTN APAC 2014 tour. Here is a list of all the posts I wrote over the course of the tour.

OTN APAC 2014 : Auckland to Birmingham

Everything went smoothly at Auckland airport. Boarding an A380 takes quite a bit of time and I was near the front of the plane, so I was in the last group to board. Fortunately there was loads of room for hand luggage and the seat was pretty good. The people too my right were a couple, so they were leaning together, which gave me more elbow room. The extra room and a plug socket meant (more...)

Loading timestamp with timezone into a table using SQL Developer

I will start this post off stating  that I know there are better and more efficient methods of doing this but this is the best method I could come up with.

I had a csv file with a number of columns, one of which was data in a timestamp with timezone format.

A few rows looked like this – note I have stripped the other columns out for ease of display.

Date Ranges in Data Warehouses using Oracle 12c

When you load data with an “effective date” into a Data Warehouse, what happens when the new data is the same as yesterday’s? Do you add a new record with the new “effective date” or do you update a date range in the existing record? At Open World last month, I got both answers: Tim Gorman […]

PeopleSoft Update Image as a Service – Proof of Concept

Together with PeopleSoft 9.2, Oracle announced the new Continuous Delivery model for delivering patches, based on PeopleSoft Update Manager. The new model allows customers to choose which fixes or enhancements they are interested in, and then just extract the objects related to them and their prerequisites.

The following diagram outlines the process of applying an update using this new delivery model:
