Oracle 11G support different OS Platform DataGaurd ( windows and linux )

I have seen it in : .

1 , The control backup in ( windows or linux ) can be used directly for mounting the Oracle database.

2 , Registering the backupset in the linux platform :

RMAN> catalog start with '/home/oracle/opt/oradata/standby';
using target database control file instead of recovery catalog
searching for all files that match the pattern /home/oracle/opt/oradata/standby

List of Files Unknown to the Database
=====================================
File Name: /home/oracle/opt/oradata/standby/db_05j3dk6n_1_1.bak
File Name: /home/oracle/opt/oradata/standby/db_04j3dk0q_1_1.bak

Do you really want to catalog the above files (enter YES or NO)? yes
cataloging files...
cataloging done
