SSRS – Report Builder a closer look

Report builder is a browser based report authoring tool to enable any end users to start building / modifying existing reports (if they have enough permissions) without the need of any installation of BIDS or SSDT. This tool is available via local installation of Report manager. This is a light weight tool that will enable you to definitely build a decent report and you can deploy it directly to the report manager. You can start building this report against SQL Server database, SQL Azure, Oracle and others. Below image also explains more on Report builder tool and also try watching a quick video on this here.

Tiny bits about Resource Governor and of course my favorite

Resource Governor helps sorry saves DBA’s life in terms of performance improvement by deriving proper lanes on what applications or which service accounts should have high horse power when it comes to CPU & I/O usage. This feature was introduced in SQL Server 2008 and made available in Enterprise, Developer and Evaluation editions only. This has got the ability to classify connections and route the workload to specific already derived lanes by DBA as per the business requirements. This is limited to SQL Server Engine only and self contained and instant specific only. This has got 3 main below concepts.

  • Resource Pool
    • Represents physical resource
  • Workload Group
    • Categorizes the sessions and routes to relevant resource pool
  • Classification
    • A function to decide the sessions to allocate the relevant group

Below picture explains the available system views, DMVs, Performance counters that are specific to Resource Governor only.

Running Stretch Database Advisor against AdventureworksDW2008R2 OLAP database

This article gives a quick glimpse on how to run SQL Server 2016 Upgrade Advisor Preview 1.2 against AdventureWorksDW2008R2 OLAP 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 AdventureWorksDW2008R2 database and clicking on Run button.


Following the analyzed database of AdventureWorksDW2008R2, 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. From below screenshot, you can see that the first table has been identified to be ready for stretch with a green tick mark, where as the next table is not eligible.




You can see the same results when the stretch database advisor is run against AdventureWorks2014 OLTP database here.

SQL Server 2016 CTP 3.0 Benefits on Stretch Database concept

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.

System Resources

Below are the main system resources and are the key elements for better performing server.
CPU: We definitely require more than one CPU to perform multiprocessing and helps any program to be healthy enough with all I/O operations.
RAM: Even if you are not a DBA, you should be aware of the memory that is allocated for your SQL Server instances. Memory Sizing can be done based on the number of transactions that is going to hit the server. Any environment having high transaction should have highly allocated memory to process multiple operations in parallel.
Disk: Disk is the storage area where every single transaction stores and retrieves data from as part of the request from applications, users. Having good amount of understanding and knowledge on database & log files and their location, on these sort of storages is a must, even for non DBA’s. Monitoring and maintaining the data storage, RAID levels, etc., are some of the key activities for every single DBAs.
I/O:  Any Input and output to and from applications/users is calculated with the I/O level. As part of the user or application’s request the I/O part plays a major role and any performance issues will affect the time taken to retrieve the data.

Snapshots in Microsoft Reporting Services

Snapshots is a great feature within Microsoft SQL Server Reporting services, to see any of your reports at that point in time. The same report cosmetics might have changed recently as part of the change request and the data will be changing everyday. How did the report looked in terms of look and feel and the data that was latest same time last year? For this question a simple answer is the snapshots. Another simple example is your photo that was taken today and comparing the same with your own photo that was taken 5 years ago. Now do you see the difference? Yes, this is an amazing option we have within Microsoft SQL Server Reporting services for your reports.

By running these snapshots of your reports, it reduces the load on the databases directly, but any amazing feature may have its own negative side as well. It is always recommended to keep less than 8 to 10 snapshots for a report in the SSRS and download the rest as a PDF and delete the previous snapshots as the data and the layout are storing in the Report Server DB and this will unnecessarily bloat your SSRS system databases. Below is also a screenshot that explains more on Snapshots. You can also view a quick demo on snapshots in this link.
