A sandbox must exist on CloverETL Server. If a sandbox does not exist, you can create it from CloverETL Designer. See CloverETL Server Project.
To each CloverETL Server sandbox, only one CloverETL Server project can be created within the same workspace. If you want to create more than one CloverETL Server projects to a single CloverETL Server sandbox, each of these projects must be in different workspace.
In one workspace, you can have more CloverETL Server projects created using your Designer.
Each of these CloverETL Server projects can even be linked to different CloverETL Server.
CloverETL Designer uses the HTTP/HTTPS protocols to connect CloverETL Server. These protocols work well with complex network setups and firewalls. Remember that each connection to any CloverETL Server is saved in your workspace. For this reason, you can use only one protocol in one workspace. You have your login name, password and some specified user rights and/or keys.
Remember that if multiple users are accessing the same sandbox (via Designer), they must cooperate to not overwrite their changes made to the same resources (e.g. graphs). If anyone changes the graph or any other resource on CloverETL Server, the other users may overwrite such resources on Server. However, a warning is displayed and each user must decide whether he or she really wants to overwrite such resource on CloverETL Server. The remote resources are not locked and user must decide what should be done in case of such conflict.
When you restart CloverETL Designer, all CloverETL Server projects are displayed, but all of them are closed. In order to open them, you have two possibilities:
Double-click the project.
Right-click the project and select from the context menu.
