Mit Social Recruiting Kosten erheblich senken

Autor Joachim Skura, Sales Development Manager Human Capital Management, Oracle DeCH

Joachim SkuraEin wesentlicher Treiber von Veränderungen im heutigen Recruiting-Prozess ist das Internet. Es ist sozusagen die «Dampfmaschine des 21. Jahrhunderts». Sich dieses Instrument zu Nutze zu machen und erfolgreich in einen modernen Recruiting-Prozess einzubauen, ist jedoch nicht ganz trivial. In der digitalen Welt gelten andere Spielregeln. Traditionelle Mechanismen sind bisweilen außer Kraft gesetzt. Richtig eingesetzt kann Social Recruiting jedoch deutliche Einsparungseffekte bewirken.

5 Minute JavaScript #7 Closures

In the previous blogpost we discussed a way to reduce the amount of global variables by using namespaces. Today, we will be looking into a different way to hide functions and variables.

If you are JavaScript on a regular basis (without being an expert) you might have heard about ‘closures’. While closures are becoming increasingly popular in other programming languages as well, JavaScript allows you to take them one step further.

Sometimes you want to run (more...)

Goldengate: Problems with character sets

One complication that you may face with replicating data using Goldengate (or other tools) is when your source character set is different to your destination character set. This is particularly true when the source character set is UTF-8 and the destination is not.

If the application does not sanitise (or you do not want to sanitise) inputs to restrict them to the lowest common denominator within your systems, you will need to ensure that you (more...)

Meet me in Austin?

Late breaking news (aka I forgot to post this earlier)! I will be speaking at the first meeting of the Austin Oracle Users Group for 2015. It will be this coming Friday February 27, 2015 starting at 11:00 AM. I will give an intro talk on Oracle SQL Developer Data Modeler (the FREE data modeling […]

Understanding vs Resolution – Statistics History Cleanup

Today I helped resolve a problem quickly but to the detriment of my understanding of exactly what was going on and why.

And as part of the quicker resolution, I had to destroy the evidence which would have helped understand better.

So… now need to go back and figure it out if I have time to model it properly, etc.

Here’s what little I know so far.

What happened was that there were a number (more...)

Exadata X5 – A Practical Point of View of the New Hardware and Licensing

Oracle recently announced its latest iteration of Exadata – X5-2. It includes a refresh of the hardware to the most recent Xeon® E5-2699 v3 CPUs. These new CPUs boost the total cores count in a full rack to 288. This is higher than the current 8 socket “big machine” version X4-8, which has only 240 cores.

But the most exciting part is the all flash version of Exadata. In the previous generation – X4 – (more...)

Bounce Counter Mismatch

EM agents can end up in several different error states and each of them have their own error image.  This one popped up in my environment this morning on one agent and all of its targets:

bounce_counter_mismatch00

A bounce counter mismatch (represented by the ‘N’ in the icon?) occurs when the agent has been restored from a backup on the remote host.  The agent is trying to upload metric data from timestampX but the repository contains (more...)

Introducing Oracle Big Data Discovery Part 2: Data Transformation, Wrangling and Exploration

In yesterday’s post I looked at Oracle Big Data Discovery and how it brought the search and analytic capabilities of Endeca to Hadoop. We looked at how the Oracle Endeca Information Discovery Studio application works with a version of the Endeca Server engine to analyse and visualise sample sets of data from the Hadoop cluster, and how it uses Apache Spark to retrieve data from Hadoop and then transform that data to make it more (more...)

Understanding enhancements to block cleanouts in Exadata part 2

In part 1 of the series I tried to explain (probably a bit too verbose when it came to session statistics) what the effect is of delayed block cleanout and buffered I/O. In the final example the “dirty” blocks on disk have been cleaned out in the buffer cache, greatly reducing the amount of work to be done when reading them.

Catching up with now, and direct path reads. You probably noticed that the migration (more...)

PeopleTools 8.54: Oracle Resource Manager

This is part of a series of articles about new features and differences in PeopleTools 8.54 that will be of interest to the Oracle DBA.

Oracle Resource manager is about prioritising one database session over another, or about restricting the overhead of one session for the good of the other database users.  A resource plan is a set of rules that are applied to some or all database sessions for some or all (more...)

Limit für die Verwendung von “colored SQL” im AWR

Das Automatic Workload Repository (AWR) gehört meiner Meinung nach zu den großartigsten Errungenschaften der jüngeren (oder auch nicht mehr ganz so jüngeren) Oracle-Geschichte, da es eine Historie von Abfragen und ihrer Performance bereitstellt. Allerdings ist diese Historie nicht vollständig, da sie auf Sampling basiert - es kann also vorkommen, dass interessante Queries nicht erfasst werden. Um dieses Problem zu lösen, wurde in 11g die Routine dbms_workload_repository.add_colored_sql eingeführt, die es ermöglicht Abfragen "einzufärben", was nichts anderes (more...)

i-Blason Prime

I replaced my OtterBox Defender with an i-Blazon Prime case when upgrading to the iPhone 6. It appeared a good option, and for 4 months it was fine. Yesterday, the latch broke and my iPhone fell to the ground as a walked. Fortunately, my iPhone landed flat, the i-Blazon plastic case absorbed the impact, and my iPhone was undamaged.

Here’s a photograph of the damaged case:
