In a WebLogic server domain set as a Production domain, when we try to connect to the Node Manager with WLST we get the following error:

This blog gives the solution to solve the issue.

En 2012, les principaux systèmes de gestion de bases de données relationnelles (SGBDR) sur le marché sont propriétaires. Nous parlons régulièrement d'Oracle Database, MySQL, Microsoft SQL Server. En dehors de ces solutions commerciales, il existe un SGDBR open-source largement utilisé: il s'agit de PostgreSQL et il est l'objet de cet article.

Recently, at a customer site, I discovered the Attunity connector 1.1 for Oracle. The customer uses this connector to transfer data from Oracle to SQL Server using Integration Services (SSIS) and informed me that performances are greatly improved. So I decided to post a blog about this connector and perform a benchmark between Attunity connector and Microsoft OLE DB provider for Oracle.

In my previous article, I announced the first fix for SQL Server 2012.

One week later, the first cumulative update is available on the Microsoft website.

With the appearance of WebLogic Server as Oracle application server and the emergence of the Oracle Fusion Middleware suite, some may wonder what will be the support of their Oracle Internet Application server license, e. g. Oracle Forms and Reports services, Business Intelligence Edition, etc. As a consultant, I am often dealing with these kinds of problems and aiming to improve license benefits. In this post, I want to focus on Oracle Internet Application server licenses.

This is just a little blog posting to announce that the first fix for SQL Server 2012 came out last week during Easter Break.

Since the commercial version of SQL Server 2012 is due to be released in April, a little posting about the changed licensing costs seems appropriate.

Who never had to measure the disk performances on a system?

Speaking about Linux performance monitoring includes a significant part of disk performances. If you are facing applications or databases running slower than expected or than on other environments, you may take a look on the I/O performances.
This posting aims to provide an introduction to a pretty interesting tool: IOzone.

In this post, I will explain how to install Oracle Fusion Middleware Forms and Reports 11g R2 for a high availability architecture on a Windows platform. For the Linux platform, it’s approximately the same, even though the node manager is a daemon.

Recently, during one of my missions, a client asked me to give him access rights to the SQL Server logs from SSMS to his application managers. As you know, you must grant the role “securityadmin” to have such rights. However, with this role you can also manage logins, CREATE DATABASEs and change passwords.

These are “too many rights” for an IT manager, but there seems to be no other way ... or is there?

Even if we (dbi services) usually advise to setup Oracle Enterprise Linux for Oracle deployments on Linux, it might appear that some customers still prefer other certified distributions such as SuSE Linux Enterprise Server (SLES). This post describes the configuration of the tmpfs filesystem size on SuSE Linux Enterprise Server 11.0 (SLES 11, without any service pack) in order to use the Oracle 11.2 Automatic Memory Management feature (AMM) through the Oracle instance parameter memory_target.

The so called Release to Manufacturing (RTM) version of SQL Server 2012 now is available.

Last week, Oracle Ace Director Jonathan Lewis held an Oracle Optimizer Workshop at dbi services Basel Area. I would like to share some of the key learnings of this really interesting exchange I experienced together with my colleagues.

Following my article about Windows 8, Microsoft today released the customer preview. This is just a small posting to announce this fresh news!

In this post, I will describe how to migrate from Oracle APEX 3.0 to Oracle APEX 4.1. I will also focus on some encountered problems as well as the new features of Oracle Application Express (APEX) 4.1.

I have been advising to use Perl for a long time in order to automate Oracle processes and operations. This week however, I tried for once to write a small procedure on a simple Linux shell (ksh and bash). This posting focuses on the shell internals and "nightmares" more than on Oracle related issues.

I have decided to take some time in this cold month of February to continue this small series. This time, I'm going to speak about Reporting Services (SSRS) and some new features. Like my other article "SQL Server 2012: New features on Integration Services (SSIS)", this article presents a summary of new features and enhancements for SQL 2012 Reporting Services.

Like other SQL server 2012 products, Integration Services has a lot of new features and enhancements. I am presenting a summary of these new "goodies" (from CTP1 to RC0), which can be powerful for DBAs and developers.

J'ai eu le plaisir de suivre une formation chez Oracle University à Colombes (Paris). En tant que stagiaire, le cours s'intitulait Oracle WebLogic Administration Essential. Ce post traite de la notion de cluster WebLogic. J'y expose les avantages du clustering WebLogic, les principaux éléments à connaître ainsi qu'un exemple de configuration via la console d'administration.

A few days ago, the dbi services consultants had the pleasure to welcome Oracle guru Martin Bach for a three day Oracle Grid infrastructure training. As many of you probably know, Martin Bach is an OakTable member and the author of 'Oracle Database 11g RAC on Linux'. He also is Oracle Certified Master and Oracle ACE.
