PowerShell profiles end in a .ps1 file extension. Normally, profiles are always loaded when working with PowerShell, However, there are several exceptions. When testing a script, you may want to invoke PowerShell but not load a profile and then run the script, this will help ensure that the script is properly coded and doesn’t use profile-specific settings.
IIS Application Pools allow for grouping of similar or related applications to facilitate easy management and configuration. Each application assigned to an application pools (or app pool) is isolated from other apps so that issues in one pool do not impact apps in other pools. Applications which have similar performance profiles or which belong to the same department in the business can be grouped together.
SQL Server holds Locks on user data to protect data integrity and this is required in every database where data gets modified. Just to emphasize, be aware that if a database is set in a READ_ONLY state SQL Server does not hold locks on data being read since it cannot be modified and so there is no data that needs to be protected, therefore SQL Server only marks the objects being accessed with an Intense Share (IS) lock to prevent a DDL statement such as dropping a table while it’s data is being read.
An event log is a windows service that manages event logging in a computer. When this service is started, Windows logs important information about the operation of the system and the applications running on it …
SQL Azure Performance Tuning is a much tougher task than SQL Server. SQL Azure lacks some of the basic tools available to SQL Server DBA’s. There really isn’t too much to do tuning your SQL Azure instance as almost all the settings available for SQL Server are automatically managed by the SQL Azure platform. However, there is still some performance tuning to be done – mostly in the execution of the operations performed by the database. A major tool missing from SQL Azure is the SQL Server Profiler, despite this however there is still some optimization that can be performed on your SQL Azure queries – you can do this by either using SSMS or SET STASTICS.
In its most basic form, creating SQL Server 2008 Integration Services packages using Business Intelligence Development Studio is a relatively straightforward process that leverages Studio’s intuitive (based on Visual Studio design guidelines) characteristics of its Designer interface. However, this simplicity is somewhat deceiving, hiding the complexity of underlying code and additional functionality associated with it. In this article, we will explore one of feature, which involves events triggered during package execution and the ability to react to their outcome through event handlers.
Master Data Services (MDS) is a master data management platform, which allows you to create a centralized hub for your master data. This single and centralized authoritative master data source provides consistent master data to all the business applications aligned to it. In this article I am going to demonstrate how model versioning works in MDS and then I will be talking about how security works in MDS.
Building and maintain a SQL Server database environment takes a lot of work. There are many things to consider when you are designing, supporting and troubleshooting your environment. This article identifies a top ten list of mistakes, or things that sometimes are overlooked when supporting a database environment.
Runtime errors and performance issues can be difficult to identify and resolve. One of the primary methods that assist with their resolution involves generating logs, which contain records of events taking place during code execution. This article provides a comprehensive overview of logging options available in SQL Server 2008 R2 Integration Services.
SQL Server 2008 Integration Services contains an assortment of predefined Control Flow tasks designed to carry out specific types of actions. Collectively, they cover a wide range of scenarios; however, their specialized nature sometimes turns out to be overly restrictive. This article explains how to accommodate these custom requirements by employing the considerably more flexible Script Task.
