For each Phase in the workflow file, the Batch Service logs the start of the Phase to the Batch database.The Batch Service reads the workflow file.The current Batch Id, Batch Execution Id, and Batch Effective Date are written to the control properties table. The target Batch database is defined in the config file. A new Batch record is created and the start of the Batch is logged in the Batch database.When a Batch starts the following sequence of events occurs. When a Batch is run, a configuration file and work flow file is passed to the Batch Service as parameters. It specifies the location of the Batch Database to use with the Batch run, and the number of concurrent Tasks that can be executed within the Batch. This is passed to the Batch Service, along with the Workflow. A Dimodelo Data Warehouse Studio Config file.The batch workflow file is passed to the Batch Service when a Batch is run. The tasks can use wildcards, so that adding tasks does not necessarily mean having to update the batch workflow. The Batch workflow file defines a set of Phases and Tasks. You can have multiple workflow files for different batches (e.g. This specifies the order of tasks to be executed in a batch. You can invoke the Batch Service via Dimodelo Data Warehouse Studio, or on the command line via Dimodelo Management Console. A table that lives in the Data Warehouse and is used by ETL tasks (like SSIS Packages and Stored Procedures) to get the current Batch Id, Batch Execution Id, and Batch Effective Date. There are a number of Components used in the Batch process. The Batch can be run directly from Dimodelo Data Warehouse Studio while developing a Data Warehouse Solution, and via the command line using Dimodelo Management Console on Test and Production servers. Over time, the Batch Manager can determine the longest running tasks, and execute them first, so that the overall Batch finishes sooner. The Batch can run multiple parallel tasks. Batch Success and Failure Notifications can be configured. Batches can be scheduled using standard scheduling tools like Windows scheduler. The Batch Database can be used to analyze Batch performance over time. Batch task progress is logged to a Batch Database. Define the workflow of the Batch and Dimodelo Data Warehouse Studio will execute the Batch Tasks in order. The Batch Management facility of the Dimodelo Management Console provides the following functions: An ETL Batch is the execution of the set of SSIS Packages that extract data from Source Systems, and transform and load the data into the Data Warehouse. NET utility that is designed to be installed on a server and used to generate code, deploy code and (mainly) run ETL batches. The Dimodelo Management Console is a small. Dimodelo Solutions provides an ETL Batch Management facility through the Dimodelo Management Console.
