Rebuld Oracle text index

We are planning to apply both patches listed below. After we applying the patches it's recommended to rebuild ALL text indexes using small_r_row storage option.   I not sure how that would apply to my create index stmt.  Looking at my create stmt how would I include the small_r_row withing the sql stmt, and would it be the same for the rest of my create sql stmts.

2.  the alter session stmt is that only run once or needed for every create index.  If the database is shutdown in the future would the alter session need to be run once again.
