Using
With the Next Generation Technology Recover for DB2 for z/OS (NGT Recover) product, you can control recovery with options that cover a wide range of recovery scenarios. These recovery scenarios are implemented by combining one or more NGT Recover commands and their options.
Note
All references to the RECOVER INDEX command or index recovery refer to the use of image copies and log. The REBUILD INDEX command or index rebuild refers to extracting and sorting index keys and building indexes. For more information, see the description of the INDEXLOG option (INDEXLOG=NO).
