Last week I gave a workshop about SQL Server 2014 and the new features. The first day we worked on new In-memory OLTP and different topics such as the new internal storage, the new transaction processing behavior or the new checkpointing process. During this day, one of the attendees asked me about the memory management with In-Memory OLTP feature. It was a very interesting question but unfortunately I didn’t have the time to discuss about it with him, so I decided to publish something concerning this topic. This subject may be extensive and time consuming, so I will try to give only a good overview to understand correctly how memory management works against memory-optimized objects and how important the monitoring aspect is in this particular context.
Recently, I have installed an Oracle 184.108.40.206 RDBMS on a server, and I wanted to install the latest Patch Set Update (PSU) 220.127.116.11.4 from October 2014. During the execution, I fell on the error "Archive not applied" and the job failed. This is how to quickly fix this issue.
In europe we have accents and non US7ASCII characters. We need special characterset. I'm not talking about Unicode here that solves all the problems. If you have a Java application, you have no problem: it's Unicode. You can store all characters in one multi-byte characterset. But for other applications, on Windows, you have 2 possible charactersets for Western Europe WE8MSWIN1252 and WE8PC850. WE8MSWIN1252 is the one that is set by default in the registry, but is it the right one?
After giving my session about SQL Server AlwaysOn and availability groups at the last French event “Les journées SQL Server 2014”, I had several questions concerning the port conflict issues, particularly the differences that exist between FCIs and availability groups (AAGs) on this subject.
You are running Oracle on VMware and are not 100% sure that you are compliant with the Oracle licensing rules? This article is for you! As I have been confronted several times with Oracle License reviews with VMware installations, I decided to write this article in order to provide answers to the most frequent questions I have received from customers.
Recently I had the opportunity to audit a SQL Server database hosted on a Hyper-V 2012 cluster. I noticed that the guest operating system had the Power Plan configured to High performance. This is great thing but when I talked to the system administrator to verify if the same option is turned on on the Hyper-V operating system, this was unfortunately not the case.
