# Update Elements, Update Parameters, Update by DC

**Update Elements** - will update inserted elements by Instance configuration, by the configuration which was used on selected Host. It will not look into the Configuration saved on computer in Configuration Files Location. **Update Size** - will update only special parameters that have # and ## symbols in front. See more about special parameters in relevant Help page. It will not update location of inserted elements. **Update by Configuration (DC)** - every time Smart Connections is used, the tool will add the shared parameter "DC" to the Host element and write name of configuration that was used:

So if you use **Update by Configuration**, the tool will read the name of the configuration from DC parameter and will find this configuration in Configuration Files Location and reinsert elements by its settings. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
