Batch mode is the traditional method of interacting with configuration management tools that do not conform to the SCC standard. In this mode, Rational Rhapsody has a custom set of properties for each tool that calls tool‑specific commands for the configuration management operations. The Lock and Unlock operations are supported only in batch mode.
SCC mode is an alternate method of interacting with configuration management tools that conform to the SCC standard. In SCC mode, you need to set only one property so that you can interface with many SCC‑compliant configuration management tools, without further customization. You interact directly with the GUI elements of your configuration management tool to execute SCC‑supported operations. Return status information, or error information in the case of failure, comes directly from the configuration management tool. Thus, you have more direct configuration management tool interaction (and receive more complete feedback on configuration management operations) in SCC mode. The Fetch and Properties operations are supported in SCC mode only.
