2 mishnayot and a good amount of Gemara! 1 - Administering an oath to one who could testify about a plaintiff, but instead denies that he saw anything - the false-oath-maker would still be exempt from the korban. One who asks a whole congregation to come forward - that's not even an oath. Plus, several other cases where the oath-taking would not be sufficient to make a false oath incur the need to bring a korban. 2 - If one insists one take the stand, but not with the language of oath - the commitment is implicit. But taking an oath in the name of the heavens and earth - no, because they are not in the Name of God. Likewise, cursing in the Name of God needs God's name. Also, the Gemara: The question of whether erasing partials of God's name counts as erasing God's name. Plus, interpretation of verses to God's power, not angels. Plus, the vineyard of Navot. When are the texts talking to God, as compared to referring to something other than God?
