Those are outer join markers.  The general idea is that Oracle's

    select ... from a, b where a.f1 = b.f2(+);

transforms to the SQL-standard syntax

    select ... from a left join b on (a.f1 = b.f2);

but I'm very fuzzy on the details beyond that (I'm not totally sure
whether the (+) denotes the left or right side of the join, even).
Anyway try googling for the terms "outer join" and "left join" and
you'll probably find some info on converting Oracle's notation to
standard.

BTW, I believe recent Oracle releases do accept the standard outer
join syntax, so you could consider converting over in general.
