The CWMS_HOME Directory tab provides information about two system variables: Local CWMS_HOME and CWMS_EXE. In most cases, you won’t need to adjust these variables.

Local CWMS_HOME

To modify the CWMS_HOME variable, check the box next to Override local CWMS_HOME directory environment setting. This will activate the Local CWMS_HOME field. You should only override CWMS_HOME if client-side scripts depend on it as a reference to the location of data and models on the client file system. For example, CWMS_HOME might be set to a watershed location to keep gridded HEC-DSS records in a database folder alongside the watershed data folder.

Local CWMS_EXE

You should only need to override CWMS_EXE if client-side scripts rely on it to locate CWMS executables or .jar files. If necessary, enter the new path in the Local CWMS_EXE field.
