Checkpointing is performed as described in Section 176 The system suspends updates to the database temporarily and carries out these actions: 1 It outputs to stable storage all log records currently residing in main memory 2 It outputs to the disk all modi ed buffer blocks 3 It outputs onto stable storage a log record <checkpoint L>, where L is a list of all active transactions

To see your SSH commands, use the show run ssh command To see what users have current SSH connections to the appliance, use the show ssh sessions command:

Recovery actions, when the database system is restarted after a failure, take place in two phases: 1 In the redo phase, the system replays updates of all transactions by scanning the log forward from the last checkpoint The log records that are replayed include log records for transactions that were rolled back before sys-

tem crash, and those that had not committed when the system crash occurred The records are the usual log records of the form <Ti , Xj , V1 , V2 > as well as the special log records of the form <Ti , Xj , V2 >; the value V2 is written to data item Xj in either case This phase also determines all transactions that are either in the transaction list in the checkpoint record, or started later, but did not have either a <Ti abort> or a <Ti commit> record in the log All these transactions have to be rolled back, and the system puts their transaction identi ers in an undo-list 2 In the undo phase, the system rolls back all transactions in the undo-list It performs rollback by scanning the log backward from the end Whenever it nds a log record belonging to a transaction in the undo-list, it performs undo actions just as if the log record had been found during the rollback of a failed transaction Thus, log records of a transaction preceding an operationend record, but after the corresponding operation-begin record, are ignored When the system nds a <Ti start> log record for a transaction Ti in undolist, it writes a <Ti abort> log record to the log Scanning of the log stops when the system has found <Ti start> log records for all transactions in the undo-list The redo phase of restart recovery replays every physical log record since the most recent checkpoint record In other words, this phase of restart recovery repeats all the update actions that were executed after the checkpoint, and whose log records reached the stable log The actions include actions of incomplete transactions and the actions carried out to roll failed transactions back The actions are repeated in the same order in which they were carried out; hence, this process is called repeating history Repeating history simpli es recovery schemes greatly Note that if an operation undo was in progress when the system crash occurred, the physical log records written during operation undo would be found, and the partial operation undo would itself be undone on the basis of these physical log records After that the original operation s operation-end record would be found during recovery, and the operation undo would be executed again.

The session ID number is shown with the show ssh sessions command NOTE If you re logging into the appliance using SSH when you are not using AAA, the username you enter is pix (for both the PIX and ASA), and the password is the password from the passwd command

Although the sales compensation program must serve many (and often competing) objectives, it is still a sales management program It is part of an array of management tools used by the sales department to manage sales productivity It does not sit independent of a fully integrated sales management modelWe suggest that the sales department act as the steward of the sales compensation program But others, such as the CEO/general manager, marketing, finance, and human resources, must have access to the design, management, and administration of the sales compensation program In this chapter, we present sales compensation program accountabilities and suggest appropriate program responsibilities who should do what to make sure the sales compensation program works effectively
