Hi..
I'm new to dba.i've a doubt on rollback segment..oracle guru's kindly help me..
Here'z the doubt..
Any DML statements(insert,update,delete) made to any table in the database has a rollback entry..
But even a create tablespace command(which is a DDL) updates the sys owned table 'ts$' in data dictionary. why there are no rollback entries from 'create tablespace' command.??

kindly help..

Rgds,
Sarav
