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.

Informatica PowerCenter Partitioning for Parallel Processing and Faster Delivery

In addition to a better ETL design, it is obvious to have a session optimized with no bottlenecks to get the best session performance. After optimizing the session performance, we can further improve the performance by exploiting the under utilized hardware power. This refers to parallel processing and we can achieve this in Informatica PowerCenter using Partitioning Sessions.

Informatica Workflow Recovery with High Availability for Auto Restartable Jobs

Restartable ETL jobs are very crucial to job failure recovery, supportability and data quality of any ETL system. In one of our prior articles we discussed different design techniques for ETL restartability, independent of the ETL tool used. We can also implement restartability in an ETL job using Informatica PowerCenter workflow recovery capabilities. In this article lets see what is required to setup an informatica workflow for recovery.

Processing Multibyte Characters Like UNICODE Characters in Fixed Width Files

Working with Multibyte Data in Fixed-Width Filess

Processing fixed width file in Informatica PowerCenter is not a big deal. But this can be bit tricky if the fixed file contins both multi byte and single byte characters such as unicode characters. This is because of the fact that fixed width flat files are byte oriented, which means the field width is measured in bytes. So if a single character takes two bytes for its representation, it will be treated as width two. In this article, lets see how such files are handled in Informatica PowerCenter.

Pipeline Lookup Transformation, Beyond Relational and Flat File Data Sources

Pipeline Lookups, Beyond Relational and Flat FIle Data Sources

Lookup transformation is synonymous to SQL outer join, which is primarily used for relational and flat file data source lookups. But with the introduction of pipeline lookup, we can use all variety of data sources in the lookup transformation. This feature is really powerful just like Active Lookup Transformation. In this article lets see how pipeline lookup transformation can be configured in a mapping.

User Defined Functions in Informatica PowerCenter

Re-Runnability for ETL Processes Which Uses Mapping Variables

Reusability is a great feature in Informatica PowerCenter which can be used by developers. Its general purpose is to reduce unnecessary coding which ultimately reduces development time and increases supportability. User Defined Functions is one among the reusability feature provided by Informatica PowerCenter. In this article lets understand User Defined Functions in detail.

Re-Runnability for Informatica ETL Processes Which Uses Mapping Variables

Informatica PowerCenter mapping variable can be effectively used to implement change data capture logic. The mapping variable is stored in the repository and its value is set to the new value only when the session execution is successful. This property makes the restartability of the ETL process easy. Since the last success point - variable value, is stored in repository, we cannot go back and reprocess an already processed data set. In this article lets see how we can handle overriding the mapping variable value.
