¹: You should avoid changing objects or storing user data in these IBM-supplied libraries or folders. You could lose or destroy these changes when you install a new release of the operating system. If you make changes to objects in these libraries, note them carefully in a log for future reference.
²: You do not need to put your server into a restricted state, but it is recommended.
³: Important: For procedures where the server does not require a restricted state, you must ensure that the server can get the locks necessary to save the information. You should place your server in a restricted state whenever you save multiple libraries, documents, or directories, unless you use the save-while-active function.
