I recently was tasked with a project to consolidate several SQL 2005 database servers down to one existing SQL 2012 database cluster. While working on this project, I found that one of the database servers needing to be consolidated was utilizing SQL Server Reporting Services (SSRS), but the existing cluster was not configured for Reporting Services. SSRS is not cluster aware, so adding this feature to an existing clustered instance is not straightforward and will likely lead to a rule check failure on the “Existing clustered or cluster-prepared instance” rule. Well today is your lucky day, as I’m going to show you exactly how to get beyond this error and on your way to making your SSRS cluster aware!
IT professionals can attest – the world in which we operate changes rapidly. For database administrators, it can be a blessing and a curse all at once. With technology continually advancing, database vendors are forced to implement new features and functionalities in order to stay competitive. Each release contains dozens of advancements and new additions that can potentially be leveraged to improve the database environments they manage. Part of what makes being a DBA so rewarding is the ability to evaluate and understand these inherent features, choosing to implement those that pose the greatest benefit to each application.
In the world of big data, we are always trying to lighten our storage footprint. Luckily for us, Microsoft has introduced data compression as an enterprise-level feature to aid in conserving storage. Not only are you able to save on storage, you will also dramatically reduce the number of I/O requests. Knowing that the disk subsystem is the slowest part of our environments, these fewer I/O requests needed for retrieving data will lead to an increase in performance.
Recently, I’ve been asked by a couple of prospective clients how RDX’s service delivery model is the correct choice for their company and their specific environment. It hasn’t been a question that I’ve honestly pondered before until lately; all I really thought about prior to getting asked this question is that we aim to strive to do the best for all of the clients that we work for and with, and that we do a great job at it.
As technology advances and organizations grow, cloud computing and hosting are becoming a part of our organizations more and more. One of the new offerings by Microsoft is their Azure platform with one of the services being the Azure SQL database. While working with the Microsoft Azure platform during a recent project, I discovered the ability to name your own Azure SQL server in the Azure Preview Portal, a feature that isn’t available in the Azure Management Portal. I’d like to share this feature with you.
As business intelligence continues to make a big splash into businesses, SSAS and cubes are becoming a requirement. One of the limitations that DBAs face every day is converting from reading and writing T-SQL statements to being able to read and write MDX with ease. In order help others who may have been thrown into the role, I am going to start a series on MDX code writing. This blog post will be geared towards translating a simple T-SQL SELECT statement into an MDX SELECT statement.
I have found that database snapshots are under-utilized and wanted to show an example of how efficient it is to use them prior to a code deploy for the purpose of recovering a single table or reverting an entire database from a snapshot in the event of unexpected functionality within an application.
If you cannot install SQL Server 2008 because of the known issue in the Setup program, you will have to use the slipstream method to successfully complete an installation of SQL Server. This method involves downloading the service pack package that you want for your architecture and combining that with the original SQL Server 2008 install media.
Recently, I was tasked with building a hierarchy using multiple dimensions. I was advised to use a named query or materialized view to accomplish this because SSAS doesn’t have the capabilities to read the columns/attributes from multiple dimensions. Since I have done this before, I decided to take the AdventureWorks database and give a step-by-step tutorial of how to accomplish this request. Let’s get started!
During your life as a DBA, you will probably have to restore the master database and all the user databases on a new operating system to bring an already existing SQL Server instance online. One of my clients recently had an issue with hardware failure. Our only option was to install SQL Server on a new OS and use the backup files to restore all the databases from the old SQL Server instance. Once the new system was completely built and we restored msdb, we noticed that some of the SQL Server Agent jobs began to fail. Below is the error output from the job history. It states that the CMDEXEC subsystem failed to load.
