OCI-19838

cannot use this control file to mount or open database

Cause

This control file was restored by a DUPLICATE operation used only to restore and recover the data files of the new database. It is not meant to be used for mounting or opening the database, as allowing so might corrupt data files or online redo logs of the target database or both.


Action

Re-create the control file manually specifying all of the names of the data files and online redo logs. Do not forget to use NID to change the name or DBID or both of the new database.
