When SQL Server 2016 was released, there were a number of enhancements that were discussed around how InMemory OLTP removed which were as limitations. I personally saw some real boot to some of the capabilities coming into InMemory OLTP especially around the concept called as Operational Analytics that Microsoft calls in this release. I am going to talk about this concept in my SQLPass session later this month in October but here is a teaser for what I learnt from this concept.

SQL SERVER – FIX Error: Maintenance plan scheduled but job is not running as per schedule
This was one of the interesting issues I solved in many days. One of my clients contacted me and told that they have scheduled a maintenance plan to take t-log backup at 10 PM but it’s not running. When we look into the job history, it was not showing any history. Some problem statements like these are interesting because they look trivial and simple – yet they are convoluted and not straightforward to solve. Let us learn how to solve Error “Maintenance plan scheduled, but the job is not running as per schedule”
SQL SERVER – Configuring Startup Options for SQL Server Management Studio
Yesterday I started my day early to get to a gym. I know this was the first day and I had loads of work pending to be completed at work too. This got me busy and I started to drive my car, oblivious of the fact that I had to take a turn which I missed. Just while crossing the junction I realized I had missed it. It was a bad start to the day as I wasted 5 minutes to retrace back to the original route. On second thought, this mistake from my side got me thinking. My mind was tuned to specific routes and this is the same thought process that got me the inspiration to write this post. Let us learn how to configure startup options.
