What I am trying to do is that I want to attach a tablespace from DB A to DB B. The reason is that I can't open DB A up due to system parameter error (spfileSID.ora). So I created a new DB B and want to copy a tablespace from DB A. Is it like doing a restore from a cold backup? Then how can I take care of control files and parameter files?
Thanks,

You can't.
You have to first restore the first database, at least a subset of it including system tablespace, undo/rbs tablespace and your tablespaces.
Then you can use transportable tablespaces.
It is impossible to directly plug tablespaces/datafiles from another database.
