Determine Oracle null == null

I wish to search a database table on a nullable column. Sometimes the value I'm search for is itself NULL. Since Null is equal to nothing, even NULL, saying

where MYCOLUMN=SEARCHVALUE 

will fail. Right now I have to resort to

where ((MYCOLUMN=SEARCHVALUE) OR (MYCOLUMN is NULL and SEARCHVALUE is NULL))

Is there a simpler way of saying that?

(I'm using Oracle if that matters)
