Making databases recoverable or nonrecoverable
You can change recoverable full-function DBs to nonrecoverable (after deleting recovery-related records from the RECON data set) by using the CHANGE.DB NONRECOV command.
You can change to recoverable again by using the CHANGE.DB RECOVABL command.
Use the LIST.DB command or the DBRC QUERY TYPE DB API request to display whether a database is recoverable.
