Dbvisit Standby upgrade

Roderick Christ

Upgrading to Dbvisit Standby 8.0.x Dbvisit provides upgrade documentation which is detailed and in principle  correct but only describes the upgrade process from the viewpoint of an installation on a single host. I upgraded Dbvisit Standby at a customer’s site with Dbvisit Standby in a running configuration with several hosts […]

ETL using Oracle DBMS_HS_PASSTHROUGH and SQL Server

Harry Dragstra

While I prefer a “loosely coupled architecture” for replication between Oracle and SQL Server, sometimes a direct (database) link cannot be avoided. By using DBMS_HS_PASSTHROUGH for data extraction the 2 other ETL processes (transformation and load) can be configured and administered with more flexibility, providing an almost acceptable level of […]

Better track the Usage of Database Options and Management Packs, or it will cost you

Harry Dragstra 2

So here it is Oracle announces a license audit, some urgency kicks in and this familiar but also really serious question comes down from management: “Are we using any unlicensed database features“. The seriousness is quite understandable, because if so, the company can look forward to some negotiations with Oracle […]

Change UUIDs in VirtualBox

Patrick Barel

If you are anything like me you will have multiple virtualboxes running on your system. Sometimes you might want to run a copy of a virtualbox for different purposes. Like running an Oracle 11 Devdays instance as test environment but also running the same vbox for customer testing. If you […]

How About Oracle Database 12c Threaded_Execution

Harry Dragstra

THREADED_EXECUTION Threaded_Execution is an Oracle Database 12c feature aiming to reduce the number of Oracle processes on LINUX. After setting parameter THREADED_EXECUTION on TRUE and a database bounce, most of the background processes are threads within just 6 Oracle processes, where more than 60 processes existed before the bounce. And […]

Oracle 12c STIG Password Generator in PL/SQL

Harry Dragstra 1

Creating or modifying an Oracle Database user password can be done by using any standard password generator you can find on the WEB. But I wanted a password to comply to “ora12c_strong_verify_function”, and this isn’t as easy to generate as you might expect. Though most generators provide options to include […]

The Oracle Public Cloud – work in progress

Lucas Jellema

Building up a public cloud is quite a challenge. Oracle has faced and overcome many challenges – and it has built up tremendous momentum to tackle the current challenge. It is stretching the company – threatening to make it spread its resources thinly. The goal is clear, the focus is […]

How to create a private 10 Gb network on an ODA X5-2

Jaap Poot

Network considerations on an ODA X5-2

Jaap Poot

When you buy an Oracle Database Appliance (ODA) X5-2 off the shelve, you will get a machine with four times 10Gb copper Ethernet (bonded into two interfaces) for public communication and two 40Gb InfiniBand (bonded into one interface) for interconnect communication between the two ODA_BASE’s. You would think that should […]

Oracle Cloud en de Europese Privacy regels; waar moeten we op letten?

Sander Mastwijk

Als Oracle gebruiker ziet u de mogelijkheden van de Oracle Cloud.  De grote flexibiliteit, de mogelijkheid om capaciteit bij en af te schalen, instant diensten en het maandelijkse verrekenmodel. Alleen al de korte doorlooptijd voor (tijdelijke) omgevingen en de verminderde beheerinspanning kunnen leiden tot een flinke verbetering in efficiëntie. Zo bent u minder bezig met de dagelijkse operatie van […]

Oracle OpenWorld 2015: Finally a real Vision and Mission. A pleasant surprise

Robbrecht van Amerongen

For me the 2015 Oracle OpenWorld was a pleasant surprise.  The surprise was not the announcement of an additional set of cloud products like the Identity Cloud or the Application Builder Cloud Service. The biggest surprise was the different tone of voice during the conference. In the past you could […]
