By Franck Pachot . Remember my first try of Oracle cloud when Larry Ellison announced the Cloud in june? This week at OOW15 Larry Ellison announced that IBM is not a competitor anymore for them, then I checked IBM Cloud: IBM Bluemix offers IaaS, PaaS and SaaS. As I did in my first trial for Oracle, I’m testing the simplest…

But from standard configuration, you will receive only one warning or critical notification/alert … until the Clear or an Acknowledge of the alert.

For the Data Region EMEA Oracle Database Public Cloud Services had maintenance on : Oracle Java Cloud Service Oracle Database Cloud Service Unfortunately it is impossible to know what specific changes have been made in the Cloud and currently there is no exhaustive list available…
By Franck Pachot . We (DBAs) look at this NoSQL hype with a large smile. We know how powerful are SQL databases and we can’t imagine processing data seriously without it. And the technologies that come with NoSQL brings back the problem that we have solved with SQL databases. But can’t we ignore what is currently going on. Behind the…
This blog is a part of the series “SQL Server 2016 – Security: Dynamic Data Masking“.

After my first blog on Security with Row level Security, I test the second Security new feature in the next version of SQL Server: Dynamic Data Masking. I presented this new feature to my Oracle colleagues and I’m surprised that Oracle 12c has the same option known as Data Redaction. The principle is simple: for some users, data are masked…
Recently at a customer we needed to power-cycle a database system because we wanted to be sure that a cluster resource fails over to a remaining node as expected. The issue was that we did not have access to the data center where the system is running nor did we have access to the console. What to do? Actually it…
By Franck Pachot . In 12c the manual switchover to physical standby requires only one command (ALTER DATABASE SWITCHOVER) instead of two (ALTER DATABASE COMMIT TO SWITCHOVER on each database). We usually recommend to use the broker and I wanted to see if the broker uses that new command or not. Let’s compare the alert.log for both manual and broker…
