11. How to log SSIS Executions?
SSIS includes logging features that write log entries when run-time events occur and can also write custom messages. This is not enabled by default. Integration Services supports a diverse set of log providers, and gives you the ability to create custom log providers. The Integration Services log providers can write log entries to text files, SQL Server Profiler, SQL Server, Windows Event Log, or XML files. Logs are associated with packages and are configured at the package level. Each task or container in a package can log information to any package log. The tasks and containers in a package can be enabled for logging even if the package itself is not.
12. How do you deploy SSIS packages?
BUILDing SSIS Projects provides a Deployment Manifest File. We need to run the manifest file and decide whether to deploy this onto File System or onto SQL Server [ msdb]. SQL Server Deployment is very faster and more secure then File System Deployment. Alternatively, we can also import the package from SSMS from File System or SQ Server.
13. What are variables and what is variable scope ?
Variables store values that a SSIS package and its containers, tasks, and event handlers can use at run time. The scripts in the Script task and the Script component can also use variables. The precedence constraints that sequence tasks and containers into a workflow can use variables when their constraint definitions include expressions. Integration Services supports two types of variables: user-defined variables and system variables. User-defined variables are defined by package developers, and system variables are defined by Integration Services. You can create as many user-defined variables as a package requires, but you cannot create additional system variables.
14. Can you name five of the Perfmon counters for SSIS and the value they provide?
? SQLServer:SSIS Service
? SSIS Package Instances
? SQLServer:SSIS Pipeline
? BLOB bytes read
? BLOB bytes written
? BLOB files in use
? Buffer memory
? Buffers in use
? Buffers spooled
? Flat buffer memory
? Flat buffers in use
? Private buffer memory
? Private buffers in use
? Rows read
? Rows written
15. What is Analysis Services? List out the features?
Microsoft SQL Server 2005 Analysis Services (SSAS) delivers online analytical processing (OLAP) and data mining functionality for business intelligence applications. Analysis Services supports OLAP by letting we design, create, and manage multidimensional structures that contain data aggregated from other data sources, such as relational databases. For data mining applications, Analysis Services lets we design, create, and visualize data mining models that are constructed from other data sources by using a wide variety of industry-standarddata mining algorithms.
Analysis Services is a middle tier server for analytical processing, OLAP, and Data mining. It manages multidimensional cubes of data and provides access to heaps of information including aggregation of data. One can create data mining models from data sources and use it for Business Intelligence also including reporting features.
Analysis service provides a combined view of the data used in OLAP or Data mining. Services here refer to OLAP, Data mining. Analysis services assists in creating, designing and managing multidimensional structures containing data from varied sources. It provides a wide array of data mining algorithms for specific trends and needs.
Some of the key features are:
? Ease of use with a lot of wizards and designers.
? Flexible data model creation and management
? Scalable architecture to handle OLAP
? Provides integration of administration tools, data sources, security, caching, and reporting etc.
? Provides extensive support for custom applications
