How to install the Oracle Integration Cloud on premises connectivity agent (18.1.3)
Recapitulation on how to install the Oracle Integration Cloud on premises connectivity agent Recently (april 2018) I gained access to the new Oracle Integration Cloud (OIC), version 18.1.3.180112.1616-762, and wanted to make an integration connection to an on-premise database. For this purpose, an on premise connectivity agent needs to be […]
A DBA’s first steps in Jenkins
My Customer wanted an automated way to refresh an application database to a known state, to be done by non-technical personnel. As a DBA I know a lot of scripting, can build some small web interfaces, but why bother when there are ready available tools, like Jenkins. Jenkins is mostly […]
Dbvisit Standby upgrade
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 […]

AWS – Build your own Oracle Linux 7 AMI in the Cloud
I always like to know what is installed in the servers that I need to use for databases or Weblogic installs. Whether it is in the Oracle Cloud or in any other Cloud. One way to know is to build your own image that will be used to start your […]
after 27+ years in Oracle land I am forced to patch sqlplus
When starting to use sqlplus 12.2 I noticed that my SQL prompt was not changing to what login.sql told it to be. This did not happen in sqlplus 12.1 or lower versions. Maybe this is a bug, maybe a new feature I thought. Behaviour in 12.2 of sqlplus indeed has […]
ETL using Oracle DBMS_HS_PASSTHROUGH and SQL Server
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 […]
Configuring Oracle Traffic Director 12c with WebGate
At a recent customer install, I was faced with configuring Oracle Traffic Director (OTD) 12.2.1.2.0 Webgate with Oracle Access Manager. Deploying Webgate on OD 12c is very well described in the documentation. See A Configuring OAM Agent (WebGate) for Oracle Traffic Director 12.2.1.2 There is however a flaw in the […]
Golden Gate 12c and DIY Sequence Replication with PL/SQL
Recently, while migrating AIX 11gR2 Databases to Oracle Linux 12cR1 on an ODA X5-2, our setup of Sequence Replication by Oracle Golden Gate appeared to be faulty. The target side sequences were not automatically incremented. The problem came to light during the migration of acceptance databases, and under some time […]
Better track the Usage of Database Options and Management Packs, or it will cost you
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
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 […]
Dump Oracle data into a delimited ascii file with PL/SQL
This is how I dump data from an Oracle Database (tested on 8i,9i,10g,11g,12c) to a delimited ascii file: Next to the query and the generated filename the Dump_Delimited function takes another 6 parameters, each one with a default value. Check out the PL/SQL, and BTW… the basics for this code […]
DIY Parallelization with Oracle DBMS_DATAPUMP
Oracle dbms_datapump provides a parallel option for exports and imports, but some objects cannot be processed in this mode. In a migration project from AIX 11gR2 to ODA X5-2 ( OL 5.9 ) 12c that included an initial load for Golden Gate, I had to deal with one of those […]
How About Oracle Database 12c Threaded_Execution
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
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 […]
Oracle Compute Cloud – Uploading My Image – Part one
Recently (October 2016) I had the opportunity to attend an Oracle Compute Cloud workshop that was very interesting. As a side effect I got access to the Cloud for a month thus I could experiment with the Cloud outside the workshop as well. I’ve had some experience with Amazon EC2 […]
The Oracle Public Cloud – work in progress
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 […]
Spark with a K – how Apache Spark is omnipresent at Oracle OpenWorld 2016
Apache Spark made numerous appearances in many different sessions during Oracle OpenWorld 2016. It is clear that Oracle is very much embracing and leveraging and endorsing Spark at various levels. Apache Spark is “a fast and general engine for large-scale data processing”. Spark has taken over from Hadoop MapReduce as […]
One of the many nice new features in 12c database: code based access control
Topic of this blog is a nice new feature in 12c, not the plsql package I built that’s using it. So here’s the story.. For one of our customers we needed to have a simple schema comparison tool that would be able to check, as part of application deployment activity, […]
Virtual columns
Maarten wrote a post on Virtual Columns in the oracle database. I read a blogpost on preventing people issuing SELECT * on a table. This was done in a different database, so I decided to try it out in my Oracle Database. First I create a simple table: and I […]
Virtual Private Database…
Some time ago I was asked to assist in fixing or at least finding the cause of a performance problem. The application ran fine until the Virtual Private Database (VPD) policy was applied. Oracle claims there should be near zero impact on your application when you implement VPD, then how […]
How to create a private 10 Gb network on an ODA X5-2
In my previous post Network considerations on an ODA X5-2 I described a solution where I created a private network to optimize network performance between the components running on an Oracle Database Appliance. I am talking about a Virtualized setup in this article, and rebuilding the second pair of public […]
Network considerations on an ODA X5-2
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?
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 […]

Reflections after Oracle OpenWorld 2015 – Announcements, Key Terminology and Roadmaps
Summarizing Oracle OpenWorld 2015 in a few headlines and key announcement is not easy. Because of the vast scope of the Oracle product portfolio (over 3000 products), the enormous variation in detail of the announcements (some very high over, some minutely detailed) and the contrast in tangibility, from generally available […]
Oracle JavaScript Extension Toolkit (Oracle JET) – announced at OOW15
Javascript is the most popular programming language* and its usage has grown 25% in the past year**. It’s widely used and so it stands to reason that Oracle now released a brand new JavaScript toolkit called Oracle JET (JavaScript Extension Toolkit). Oracle says “Oracle JET is targeted at intermediate to […]
Oracle OpenWorld 2015: Finally a real Vision and Mission. A pleasant surprise
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 […]
