The following example will demonstrate how to use the Create / Edit a context group wizard to create a context group named TalendDB that contains two contexts named Prod and Test and define a set of variables - host, port, database, username, password, and table_name - under the two contexts in the Repository, for reuse in database handling Jobs.
Once you created and adapted as many context sets as you want, click Finish to validate. The group of contexts thus displays under the Contexts node in the Repository tree view. You can further edit the context group, contexts, and context variables in the wizard by right-clicking the Contexts node and selecting Edit context group from the contextual menu.
