Use of RMAN maxpiecesize command

To avoid large size of backupset we can set maxpiecesize of rman backup piece.

I have taken following backup without setting any parameter :

By list backup command we can see all details of backup , here we can see my backup set size is 1013.84M.

now configure maxpiecesize to 50M.

then take full backup of database using RMAN backup database command .

Check backup piece size using list backup command .

Here we can see BP key [backup piece key] under Backup Set , 21 different backup pieces are created.

Thank you for giving your valuable time to read the above information.
