How to Avoid The Usage of SQL Overrides in Informatica PowerCenter Mappings

Many Informatica PowerCenter developers tend to use SQL Override during mapping development. Developers finds it easy and more productive to use SQL Override. At the same time ETL Architects do not like SQL Overrides as it hide the ETL logic from metadata manager. In this article lets see the options available to avoid SQL Override in different transformations.

Surrogate Key Generation Approaches Using Informatica PowerCenter

Different Approaches to Generate Surrogate Key in Informatica PowerCenter

Surrogate Key is sequentially generated unique number attached with each and every record in a Dimension table in any Data Warehouse. We discussed about Surrogate Key in in detail in our previous article. Here in this article we will concentrate on different approaches to generate Surrogate Key for different type ETL process.

Time Zones Conversion and Standardization Using Informatica PowerCenter

When your data warehouse is sourcing data from multi-time zoned data sources, it is recommended to capture a universal standard time, as well as local times. Same goes with transactions involving multiple currencies. This design enables analysis on the local time along with the universal standard time. The time standardization will be done as part of the ETL, which loads the warehouse. In this article lets discuss about the implementation using Informatica PowerCenter.

Dynamically Changing ETL Calculations Using Informatica Mapping Variable

Quite often we deal with ETL logic, which is very dynamic in nature. Such as a discount calculation which changes every month or a special weekend only logic. There is a lot of practical difficulty in making such frequent ETL change into production environment. Best option to deal with this dynamic scenario is parametrization. In this article let discuss how we can make the ETL calculations dynamic.

Session Logfile with Verbose Data for Informatica Mapping Debugging

Troubleshoot Informatica Mapping Using Verbose Mode Session Log

Debugger is a great tool to troubleshoot your mapping logic, but there are instances where we need to go for a different troubleshooting approach for mappings. Session log file with verbose data gives much more details than the debugger tool, such as what data is stored in the cache files, how variables ports are evaluated. Such information helps in complex tricky troubleshooting.

Mapping Debugger to Troubleshoot your Informatica PowerCenter ETL Logic

Debug Informatica PowerCenter Mapping Using Debugger and Session Log File

Debugger is an integral part of Informatica PowerCenter mapping designer, which help you in troubleshooting the ETL logical error or data error conditions in an Informatica mapping. The debugger user interface shows the step by step execution path of a mapping and how the source data is transformed in the mapping. Features like "break points", "evaluate expression" makes the debugging process easy.

Dynamic Partitioning to Increase Parallelism Based on Resources Availability

Informatica PowerCenter session partition can be used to process data in parallel and achieve faster data delivery. Using Dynamic Session Partitioning capability, PowerCenter can dynamically decide the degree of parallelism. The Integration Service scales the number of session partitions at run time based on factors such as source database partitions or the number of CPUs on the node resulting significant performance improvement.

Informatica PowerCenter Pushdown Optimization a Hybrid ELT Approach

Informatica PowerCenter Pushdown Optimization an ELT Approach

Informatica Pushdown Optimization Option increases performance by providing the flexibility to push transformation processing to the most appropriate processing resource. Using Pushdown Optimization, data transformation logic can be pushed to source database or target database or through the PowerCenter server. This gives the option for the ETL architect to choose the best of the available resources for data processing.

Implementing Informatica PowerCenter Session Partitioning Algorithms

Implementing Different Informatica PowerCenter Session Partitioning Algorithms

Informatica PowerCenter Session Partitioning can be effectively used for parallel data processing and achieve faster data delivery. Parallel data processing performance is heavily depending on the additional hardware power available. In additional to that, it is important to choose the appropriate partitioning algorithm or partition type. In this article lets discuss the optimal session partition settings.
