"If we are setting a table level lock both the blockId and tupleId (in an item pointer this is called the position) are set to invalid, if it is a page level lock the blockId is valid, while the tupleId is still invalid. Finally if this is a tuple level lock (we currently never do this) then both the blockId and tupleId are set to valid specifications. "
is blockId same as tag.objId.blkno? what field in LOCK.tag is tupleId? thanks jenny
