Below is the cheat chart, which will give you a quick glimpse on most of the possible issues, that you face in your day to day SQL Server life. This chart also provides you with available SQL Server Admin tools from left to right in the top, to tackle the issues that are relevant to your problems. This also explains a good understanding on available SQL Server admin tools that can be used to tackle problems that you may be facing in your work environment. At least now you know where to start if you hit with any performance or other issues.
SQL Server 2016 Upgrade Advisor 1.2 allows you to run Stretch Database Advisor to find the tables within the selected database, whether qualified for database stretch or not. This SQL Server 2016 upgrade advisor also allows you to run below.
As we are very much excited with the improved version of Microsoft SQL Server CTP 3.0 release, below are some of the main benefits of this release towards the Stretch Database concept.
With the stretch enabled database, there are no updates required for any applications which we believe the change is required as the data has completed moved to Azure. Though the data has been moved to cloud, the table reference still has to the same local table.
As the data is moved to the cloud, you don’t have to keep expanding your local storages and can save money.
Though there is a bit of delay in accessing the data from the cloud, the performance has been still improved.
No more hassles in backing up and restoring huge databases which stores data locally. Now the data stretched to the cloud, you will only backup what is available in the local database files.
You can now easily manage Database stretch in GUI format within SSMS to pause, disable, enable, reconfigure, monitor, etc.,
CTP 2.0 did not allow connecting to already existing server in the cloud and this has been fixed in later releases.
As you can see from the below slide, these are the identified issues and limitations that we have with the Stretch database within SQL Server 2016 CTP 3.0 release. A table that has more than 1023 columns or 998 indexes is not eligible to stretch it to Azure. Also the constraints like Check, Foreign Key, Default are also a huge restrictions placed on OLTP schema systems. This Stretch database concept highly works with OLAP based systems and /or if any table that is been isolated without any relations to anyother table. You can also check this article to identify whether any tables within your database is qualified for stretch or not.
This article gives a quick glimpse on how to run SQL Server 2016 Upgrade Advisor Preview 1.2 against AdventureWorks2014 OLTP database. Once you shoot the Upgrade Advisor, go to Scenarios and then select the first option “Run the Stretch Database Advisor”. Following this, you will get below screen and then click on Select Databases to Analyze. This will then shoot the blade option to select the databases but requires you to connect to which instance the database is located. In the below example I am connecting to my YSMLab01\SQL2016 instance.
After choosing the instance, I am selecting AdventureWorks2014 database and clicking on Run button.
Following the analyzed database of AdventureWorks2014, it has identified the database size and total number of tables being analyzed. By clicking on this result set it further displays the list of tables with status on eligibility to cloud or not. If it has errors then it gives out the reasons on why it is not selected in blade format.
In here, I am further trying to find the problem on why Person.Person was not selected and one of the reasons is because of Default Value Constraints on one or more columns cannot be part of stretch database.
You can see the same results when the stretch database advisor is run against AdventureWorksDW2008R2 OLAP database here.
In the Data Awareness Programme to students, I have shown below slide to let them know on how many versions have released, so far. As you can see below, the first ever version released was in 1989 and we are in 2014 now. SQL 2016 CTP versions are available but expected to release in beginning of 2016. There were totally 13 releases in last 25 years and the product has become very much stronger than ever. SQL 2016 is going to be a huge one with easy integration to cloud.
In my Data Awareness Programmes, I also spread the available SQL Server features from 2000 to 2014 in below slide formats. This will also give a quick glimpse on all SQL Server releases with available features in one single article. Note: These slides covers only a noticeable features and does not cover every single feature on it.
