Data Loader CLI

Data Loader CLI (Command Line Interpreter):
* For automating the batches and schedule them using windows "Task Scheduler".
* We can perform import as well as export.

Windows-7 Task Scheduler

* We can do all the same things from the command line - insert data, update data, upsert data, delete data or extract data.
* Instead of "export", we should use "extract".
* We can move data to and from a comma-separated variable file (.csv) or to and from a relational database, such as Oracle or SQL Server, that has a standard JDBC driver.
* With a default installation on a Windows machine, all the Data Loader files will be placed in the Program Files\salesforce.com\Apex Data Loader APIversion directory, where APIversion corresponds to the API version.
* The process command, encrypt command will be in the bin subdirectory, and the configuration files will normally be in the conf subdirectory.
*The main configuration file used by the CLI is the process-conf.xml file.
* The process-conf.xml file contains a description for every potential process that could be called from the command line.
* Each of these processes is referred to as a Process Bean. 
* In this simple example, there is only one Process Bean in the process-conf.xml file.
* In normal practice, though, you would have a number of Process Bean sections in the configuration file, so calling out the specific process would make sense.
* The process-conf.xml file consists of a set of property-value pairs.
* The file used for this sample process is shown below, with an explanation of the key entries following the listing.

 Configuration properties:

The process-conf.xml file contains properties for one or more Process Beans. Some of the more important properties are

• name - used to identify the bean in the config.properties file and when you call it from the CLI
• sfdc.entity - the Salesforce object that is the target of the actions. The value of this property is case sensitive.
• process.operation - identifies the type of operation
• process.mappingFile - identifies the mapping between the fields in the source file (dataAccess.name) and the Salesforce object. This mapping file is a .sdl file. The mapping file is the same format as the .sdl file created by the GUI when you save a mapping scheme.
• dataAccess.type - identifies the operation to perform on the source file
• sfdc.username - your Salesforce.com user name 

* To schedule the file we should open windows Task Scheduler.

C:\Program Files (x86)

-- Save it as filename.bat--
