How long has toy story midway mania been operating at disneyland?

The attraction known as Toy Story Midway Mania! was first unveiled during a press conference at Walt Disney World in January 2007 and opened at Disney California Adventure on June 17, 2008. It is also located at Disney's Hollywood Studios (opened May 31, 2008) and Tokyo DisneySea (opened July 9, 2012). Disneyland Park itself does not host this attraction, so it has not been operating there. If you are looking for the attraction at the Disneyland Resort, you would find it at Disney California Adventure, which has been in operation for over 18 years.
