Microsoft SQL Server
In this post I’ll Briefly cover the changes to SQL Server licencing which happened in two areas, edition changes and licensing changes. Lets get started.
Use NOLOCK hint to avoid block – this is what I have often heard/see in many forums I participate in, during local user group events and meetings. I have always advised that its not that good idea to use hints, as it may cause data corruption and blocking. And anyways, there are many things that you can do to avoid blocking, like:
In this blog, I am going to demonstrate how we can use the wait event category sqlos.wait_info* to track the wait resources the queries running in a particular session undergo.
If you ever used SQL server Database Engine Tuning Advisor then you know you have few options as a source of analysis workload, here they are.
If you do any performance tuning , and everyone does, then you’ll come to a point where you want to know if your tables have sufficient indexes to serve the queries fast, here’s how.
After an in place upgrade of SQL server 2005 to SQL server 2008 R2 , I tried to open SQL errorlog from Management> SQL server logs but I got the following error. Here’s how I fixed it.
A simple example of BBCode would be to make some text bold , this can be simply written like that [b]Bold Text[/b] or italic [i]italic text[/i].

Sometimes clients ask us to implement scripts that change objects in their schemes. In order to prevent the situation when these scripts hung just because some, or several, objects are pinned. Here are two simple procedures that can help to check what we will get during our maintenance.
I was reading my session evaluation results and came accross comment that said: “copy and paste coder.” I’ve been doing this specific presentation for almost 5 years now with a few tweaks every once in a while based on feedback. Yes, I live and breathe disaster recovery as part of my day-to-day job. However, there are several reasons why I do not type nor write code during my presentations. Here are a few of them.
I was working on a task where I had to confirm if the direct IO is in use or not. filesystem_io_option database parameter was set to “DIRECTIO” to make use of directio. Initially I was looking for same kind of memory structures in Solaris but could not find so ( bad luck :( ) and so used basic tracing using truss.First I logged into database and check the filesystem parameter ( Changed the name of the database and host :) )
