RMAN Crosscheck Clause

Check whether backup pieces, proxy copies, or disk copies still exist in comparison to the control file's repository.

Syntax:

  CROSSCHECK
    { 
      { BACKUP [OF listObjList] 
      | COPY [OF listObjList] 
      | archivelogRecordSpecifier 
      } [maintQualifier [maintQualifier]…] 
    | recordSpec [DEVICE TYPE deviceSpecifier [, deviceSpecifier]…]
    };

   listObjList::=
      [ DATAFILE datafileSpec [, datafileSpec]… 
      | TABLESPACE ['] tablespace_name ['] [, ['] tablespace_name [']]… 
      | archivelogRecordSpecifier 
      | DATABASE [SKIP TABLESPACE ['] tablespace_name [']
           [, ['] tablespace_name [']]…] 
      | CONTROLFILE
      | SPFILE
      ]…

Use RMAN Crosscheck to check that files are in place ready for a restore.
To validate a restore has worked, use the RMAN restore validate command.

Examples:

Assuming you have configured automatic channels:

RMAN> CROSSCHECK BACKUP;
RMAN> CROSSCHECK COPY;
RMAN> CROSSCHECK backup of database;
RMAN> CROSSCHECK backup of controlfile;
RMAN> CROSSCHECK archivelog all;

Query the media manager for the status of backup sets in a given date range:

RMAN> ALLOCATE CHANNEL FOR MAINTENANCE DEVICE TYPE sbt;
RMAN> CROSSCHECK BACKUP DEVICE TYPE sbt COMPLETED BETWEEN '01-AUG-04' AND '31-DEC-04';
