How the repository server communicates with the repository database The Repository Server can manage a repository residing on a database on a different machine on the network Using the repository manager, the entire repository can be backed up in the format of How the repository server create and update the repository tables When you connecting to the repository, you need to mention the What is the default repository server connection timeout limit For executing a workflow, the PowerCenter server uses the The primary PowerCenter server process is known as what are the servers available in informatica

A worklet is an object that represents a set of When the Informatica Server executes a worklet, it expands the worklet. When a mapplet is changed, all instances of the mapplet and all shortcuts to the mapplet Like a reusable transformation, any change made to the mapplet is inherited by all instances of the mapplet. Which component is responsible for reading the parameter file and expanding the flow variable values for the workflow When the Designer validates a mapping variable in a reusable transformation, it treats the variable as To debug a mapping, you need to configure and run the Debugger from The place where debugger pauses and allows you to view and edit transformation output data is known as In general, how many different types of log files are created by PowerCenter Server

With the error tracing level enabled, the Informatica Server logs each row that passes into the mapping By default, the PowerCenter Server does not save multiple logs for a single workflow. When the Server runs in recovery mode, it continues to commit data from the point of the last successful commit As a important requirement for data recovery, the source data needs to be To help you determine which column caused the row to be rejected, the server adds this components to reject files When you configure partitioning for a mapping, which partition type distributes data evenly among all partitions. By default, the PowerCenter Server sets the number of partitions to A block of memory for temporary storage of data likely to be used again is known as If the data doesnt fit in the memory cache, the server stores
