Having worked for several years as an Oracle DBA, I decided to have a look at the PostgreSQL database and see how it functions in comparison to the Oracle Database. The “Enterprise DB” graphical installation of PostgreSQL 9.3 is quite easy and rather fast. Under Linux you run the graphical installer, dialog boxes lead you through the installation process. You enter the specific information of your system and at the end of the PostgreSQL installation,…

Today, I am beginning my second TechDay by a session about Optimizing T-SQL. You need to know about this if you are using SQL Database or Microsoft SQL Server 2012. Tobias Ternström, Lead Program Manager, was the speaker of this session. His team, five hundred persons, works on SQL Server engine and mostly focuses on performance. There are 3 three different ways to run SQL: Physical machine can be scale-up full control roll your own…
Finally after some months … The Oracle’s long-awaited 12c database (220.127.116.11) is now available for download on OTN and Oracle E-delivery ( http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html). Without any surprise the first platforms are Linux and Solaris! Weird, but until now no “official” announcement from Oracle has been made… Have a look on all new features integrated in this release: http://docs.oracle.com/cd/E16655_01/server.121/e17906/chapter1.htm#NEWFTCH1
A few weeks ago, I went to the Swiss Database Days 2013 and followed the “Practical SQL Server Performance Troubleshooting” workshop. During this workshop, I have seen a different way of troubleshooting, but I was surprised to see that some participants were not aware that some basic SQL Server Best Practice do not depend on the instance settings. This blog posting is a reminder of some of these points. Swiss Database Days 2013: SQL Server…
Database Vault solution allows to create rules that manage access to database. Among these rules there is what is called in Database Vault “Rule Sets”. These logic components are written as PL/SQL functions to return Boolean results.
If rule expressions do not match the user context, the access is refused and a specific message can be configured in order to warn the user that he is not authorized to access this specific object. These expressions can be for instance related to the client IP address, the session username, the time or date and many other things.
This morning, I was very happy to go to my first TechEd. Between the 10 seminars, as I said yesterday, I started with SQL Server 2008R2/2012 performance, tuning and optimization session. The thing is that we had just one session for the whole day. I will not copy the presentation of the 2 speakers (Thomas LaRock and Denny Cherry) who presented remarkably this session despite the failure of air conditioning during the morning. Fortunately, it…
I have seen at a customer that the SQL Server’s policy doesn’t follow the Microsoft’s recommendations about antivirus and databases(kb 309422), such excluding *.mdf,*.ndf and *.ldf files. In addition the policy for Oracle doesn’t exist in case of Forefront Endpoint Protection 2010 known as FEP 2010.
I have decided to create databases policies for FEP optimized by dbi services to be generic and adapted to all SQL Server and Oracle environments.
Dynamic management views (DMVs) return server state information that can be used to monitor the health of a server instance, diagnose problems and tune performance.
Since few months, I test the future new version SQL Server 2012 codename Denali and I was very surprised form the news DMVs from this version.
I will just explain some DMVs very interesting for a DBA.
My article is based on msdn web site reference and you find in the end from each chapter a msdn reference for more details of the DMV.
In my experience, I have seen many clients do not know how to do when they have multiple databases instances and Integration Servicet for manage the end of the instance that is the reference for Integration Services.
When Integration Service is installed with the instance “TOTO” and that it is at the end of his life, we’ll see how to transfer information to the second instance “TITI”. We present you a small working method to transfer information correctly.
Only the folders transfert is presented in this article and the transfert of the SSIS packages are explained at the end.
