Sometimes as developers we find ourselves locked out of the Informatica PowerCenter environment preventing us from verifying if a particular folder, target, source or parameter file exists in the PowerMart directory. Using a Java Transformation provides a potential solution to this problem. The following will explain how to build a Java Transformation that takes as input the PowerMart root directory or any directory the Informatica PowerCenter account has access to and return information about all the files within the directory and its sub-directories as rows.
Command-line tasks are great components that can facilitate reusability, standardization and scalability of processes tied to PowerCenter workflows. Building a library of reusable command tasks to be used throughout a Subject Area can be beneficial for such tasks as managing dependencies, tracking objects or interface/integrate with processes or tools external to PowerCenter.
