Creating RMAN catalog. Are these steps correct?

Question

Are these steps to set up the RMAN catalog correct?
I.
The following two databases are the target databases which needs to be backed up.
1. a 11.1.0.7.0 database
2. a 10.2.0.1.0 databaseII.
Catalog schema in a 10.2.0.4.0 database called catdb.
III.
I am going to use the RMAN client(10.2.0.1.0) in my laptop (Windows Server 2003).
CATALOG schema creation
=======================
To create the Catalog Database (10.2.0.4.0), this what i am going to do in catdb
     a. create tablespace CAT_TBS
     b.     CREATE USER rman_cat_schema
          IDENTIFIED BY rman_cat_schema
          DEFAULT TABLESPACE cat_tbs
          TEMPORARY TABLESPACE temp
          QUOTA UNLIMITED ON cat_tbs;
     c.      GRANT create session TO rman_cat_schema;
     d.      GRANT recovery_catalog_owner TO rman_cat_schema;
     e.      GRANT execute ON dbms_stats TO rman_cat_schema;
   f. Invoke the <font color="red"><b>RMAN binary from my laptop</b></font> :
              C:\>set ORACLE_SID=catdb
           C:\>rman catalog rman_cat_schema/rman_cat_schema@catdb log=catalog.log
                           Hopefully Catalog will get the created at catdb .
Registering the database
=========================
To register the database,this is what i am going to do.
     a. Add the Tns Entry about the catdb in tnsnames.ora file of the target database
     b. Log in to target database's machine and invoke the<font color="red"><b> RMAN executable in the target database. </b></font>
        $  export ORACLE_SID=oraprod314
        $  rman TARGET / CATALOG rman_cat_schema/rman_cat_schema@catdb
             c. Then i can give the REGISTER DATABASE command. like
             $rman > register database;

Answer 1

Yes, You can connect to RMAN catalog using a lower version client. see this.
SQL> conn rman/rman@mycatdb
Connected.
SQL> select * from rcver;
VERSION
11.01.00.06
SQL>
rman
Recovery Manager: Release 9.2.0.7.0 - 64bit Production
Copyright (c) 1995, 2002, Oracle Corporation. All rights reserved.
RMAN> connect target /
connected to target database: STSTDB (DBID=2045697105)
RMAN> connect catalog rman/rman@abcd.
connected to recovery catalog database
RMAN>
You can take the backups and do recoveries. But, if you want to achieve certain features of the recovery catalog of higher versions to backup / recover your database, you better use the right RMAN client which allows the features to use.
It is always advisable to use the RMAN Client same as the database version you want to backup to avoid any confusions.
Hope it is helpul.
