Oracle KFED
Version 12.1.0.1

General Information
Library Note Morgan's Library Page Footer
The Library is currently in the process of being upgraded from Oracle Database Version 11.2.0.3 to 12.1.0.1. Demos are being upgraded to reflect the new Container paradigm as well as EBR (Edition Based Redefinition) and may contain references to CDBs, PDBs, and other objects you may not be familiar with such as CDB_OBJECTS_AE: Welcome to 12c.
Purpose The kfed is an undocumented utility located at $ORACLE_HOME/bin that can be used to support ASM deployments. The kfed does not depend on the mount state of an ASM instance or ASM disk group, so it can be used with ASM instance down and on a disk group that does not mount. KFED can also be used on ASM disks with corrupt ASM metadata.
