I see a different output or behaviour of RMAN 'backup database' command using "format keyword" when I keep the part of the syntax once in the middle and the other in the end it stores backup at different location as mentioned in the below cases

In the below case 1 - I used the format keyword in the middle and it saves the backupsets in the defined location, however if I use the same command with format keyword in the end it stores the backup pieces in ORACLE_HOME/dbs location. Not sure, why it does that. Any ideas would be really appreciable.

Note : - FRA parameters are not enabled as earlier it was storing the backup pieces to FRA location while using case2.

Case 1 : - Using the format keyword in the middle.

RMAN> backup format '/o/export/export/cold_test/backup_%U_%u_%t_%d' incremental level 0 database plus archivelog ;

The backup command contains two keys file formats. The first key format defines the location and format of the backup file for the database itself, the second key format defines the location and format of the backup file for archive logs.

RMAN> backup format '/o/export/export/cold_test/backup_%U_%u_%t_%d'  incremental level 0 database plus archivelog format '/o/export/export/cold_test/backup_%U_%u_%t_%d' ;
