A system and method are disclosed for providing journal recovery in a multi-node environment which comprises determining whether a block was updated by a first node; determining whether the block is associated with a lock held by a second node; and writing the block to a final location if the block is not associated with a lock held by the second node. The system consists of a first switch that couples the rectified output of the first power supply to the ultimate rectified output, and a second switch that couples the rectified output of the second power supply to the ultimate rectified output. Each strap also engages the inner surface of the masonry wall. Angles \u03b83, \u03b81 and \u03b82 satisfy the relation \u03b81<\u03b83<\u03b82. 01% by weight and no greater than 0.
