A lock on an element prevents another user from editing that element. There are two types of locks: user locks and system locks. When an element is locked by you, you have a user lock. The element is read-only to all other users on the Integration Server. Another user cannot edit the element until you unlock it.

When an element’s supporting files (node.xml, for example) are marked read-only on the Integration Server, the element is system locked. For example, the server administrator has the ability to mark an element’s supporting files on the server as read-only, in which case they are system locked. To edit the element, you must ask the server administrator to remove the system lock (that is, make the element’s files writable), and then you must reload the package in which the element resides.

Elements are shown in the following ways in Designer’s Package Navigator:
