Give the message flow and log entries for the hierarchical 2PC protocol for this scenario. Indicate which log entries need to be immediately forced to the stable log.

Consider the following scenario. A transaction is initiated from a PC to make reservations for a vacation. The initiator communicates directly with a travel agency and a rental car company. The travel agency communicates with a travel wholesaler, which books two of the necessary flights (or flight legs) on the servers of the corresponding airlines, and also with two other airlines to book the rest of the necessary flights. All these steps belong to one distributed transaction, and all involved participants are able and willing to commit the transaction. The communication structure of this transaction is illustrated in Figure 19.12.

(a) Give the message flow and log entries for the hierarchical 2PC protocol for this scenario. Indicate which log entries need to be immediately forced to the stable….

All processes have performed updates and the transaction commits,

Consider a binary, perfectly balanced tree of processes of height n where all leaf nodes have the same distance from the root; so there is a total number of m = 2 n − 1 nodes in the tree. Assume that the root is the coordinator of the commit protocol. Determine the number of messages and forced log writes for the presumed-nothing (i.e., basic 2PC), presumed-abort, and presumed-commit protocols for the following situations:

(a) all processes have performed updates and the transaction commits,

(b) all processes have performed updates and the transaction aborts,

(c) all nonroot nodes are read-only and the transaction commits,

(d) all leaf nodes are read-only and the transaction commits

Discuss how this case illustrates the contrasts between the administrative use and developmental use of appraisals

Bristol-Myers Squibb (BMS) is one of the world’s largest pharmaceutical firms and is widely known for its innovative research. However, the firm has not limited its innovations to products. Several years ago, BMS leaders decided that the company’s performance management system needed to be re-invented. Specifically, they determined that the existing performance appraisal process was not working. Managers were “form focused,” meaning that they were so concentrated on filling out the performance review forms; the content of the forms was not being used for employee coaching and based on development. In addition, most of the attention of managers and employees was historical and based on what employees had done in the past. Little attention was being given to how employees could develop and improve in the future. The….

Gardner Company currently makes all sales on credit and offers no cash discount.

1. Gardner Company currently makes all sales on credit and offers no cash discount. The firm is considering offering a 2% cash discount for payment within 15 days. The firm’s current average collection period is 60 days, sales are 40,000 units, selling price is $45 per unit, and variable cost per unit is $36. The firm expects that the change in credit terms will result in an increase in sales to 42,000 units, that 70% of the sales will take the discount, and that the average collection period will fall to 30 days. If the firm’s required rate of return on equal-risk investments is 25%, should the proposed discount be offered? (Note: Assume a 360-day year.)

A retailer of a perishable item that has a life of 3 months is in a dilemma.

A retailer of a perishable item that has a life of 3 months is in a dilemma. The forecast for the three months (which is a function of the price charged) is expected to be 2500 – p1, 2500 -1.2 p2 and 2500 – 1.55 p3 respectively. If the purchase price of the item is Rs 200 and if the retailer wants to charge the same price in each of the three months, what price (optimal) should he charge, how much should he order and what is the expected profit? Excel output to be provided.

If he were to follow dynamic pricing, how can you get the prices to be charged in the three months? Do you foresee any advantage in following this?
