The specified library cannot operate in stand-alone mode such as DUMP DB or RESTORE DB.
The requested operation fails.
If this is a FILE library, use a device class that does not use a FILE library. A FILE device class does not need a library, and thus, can be updated with LIBRARY="" and SHARED=NO. Update your device configuration file appropriately for the stand-alone operation, and then if needed, return the device class to its original state using a FILE library or with SHARED=YES when the server is running.
