How to skip unwanted tablespaces from restoration & recovery

user11982706Feb 1 2013 — edited Feb 5 2013
DB Version : 11.2.0.1.0
OS Version : AIX 6.1

I have full backups (Level 0, Level 1, archives, controlfile, spfile) for a database. Now, i have to restore & recover this database on another server. I know few tablespaces which are not required. It means, those tablespace are just for backup of tables etc and if those tablespaces are not restored & recovered then also it fine. My main idea is to save time by not restoring & recovering unwanted files. Here is report schema output.
RMAN> report schema;

Report of database schema for database with db_unique_name CORE

List of Permanent Datafiles
===========================
File Size(MB) Tablespace           RB segs Datafile Name

I have used "RMAN> sql 'alter database datafile 4 offline for drop';" to take only datafile for tablespaces users offline. Below are the complete logs.

RMAN> alter database open resetlogs;

database opened
new incarnation of database registered in recovery catalog
starting full resync of recovery catalog
full resync complete
But in logs i can see that datafile 4 is still restored which means i am spending extra time on restoring file which i don't need. Is there any way to achive this ?
