Error handling is more complicated with persistent messaging than with twophase commit For instance, if the account where the check is to be deposited has been closed, the check must be sent back to the originating account and credited back there Both sites must therefore be provided with error handling code, along with code to handle the persistent messages In contrast, with two-phase commit, the error would be detected by the transaction, which would then never deduct the amount in the rst place The types of exception conditions that may arise depend on the application, so it is not possible for the database system to handle exceptions automatically The application programs that send and receive persistent messages must include code to handle exception conditions and bring the system back to a consistent state For instance, it is not acceptable to just lose the money being transfered if the receiving account has been closed; the money must be credited back to the originating account, and if that is not possible for some reason, humans must be alerted to resolve the situation manually There are many applications where the bene t of eliminating blocking is well worth the extra effort to implement systems that use persistent messages In fact, few organizations would agree to support two-phase commit for transactions originating outside the organization, since failures could result in blocking of access to local data Persistent messaging therefore plays an important role in carrying out transactions that cross organizational boundaries Work ows provide a general model of transaction processing involving multiple sites and possibly human processing of certain steps For instance, when a bank receives a loan application, there are many steps it must take, including contacting external credit-checking agencies, before approving or rejecting a loan application The steps, together, form a work ow We study work ows in more detail in Section 242 We also note that persistent messaging forms the underlying basis for work ows in a distributed environment We now consider the implementation of persistent messaging Persistent messaging can be implemented on top of an unreliable messaging infrastructure, which may lose messages or deliver them multiple times, by these protocols: Sending site protocol: When a transaction wishes to send a persistent message, it writes a record containing the message in a special relation messagesto-send, instead of directly sending out the message The message is also given a unique message identi er A message delivery process monitors the relation, and when a new message is found, it sends the message to its destination The usual database concurrency control mechanisms ensure that the system process reads the message only after the transaction that wrote the message commits; if the transaction aborts, the usual recovery mechanism would delete the message from the relation The message delivery process deletes a message from the relation only after it receives an acknowledgment from the destination site If it receives no acknowledgement from the destination site, after some time it sends the message again It repeats this until an acknowledgment is received In case of permanent failures, the system will decide, after some period of time, that the.

message is undeliverable Exception handling code provided by the application is then invoked to deal with the failure Writing the message to a relation and processing it only after the transaction commits ensures that the message will be delivered if and only if the transaction commits Repeatedly sending it guarantees it will be delivered even if there are (temporary) system or network failures Receiving site protocol: When a site receives a persistent message, it runs a transaction that adds the message to a special received-messages relation, provided it is not already present in the relation (the unique message identi er detects duplicates) After the transaction commits, or if the message was already present in the relation, the receiving site sends an acknowledgment back to the sending site Note that sending the acknowledgment before the transaction commits is not safe, since a system failure may then result in loss of the message Checking whether the message has been received earlier is essential to avoid multiple deliveries of the message In many messaging systems, it is possible for messages to get delayed arbitrarily, although such delays are very unlikely Therefore, to be safe, the message must never be deleted from the received-messages relation Deleting it could result in a duplicate delivery not being detected But as a result, the received-messages relation may grow inde nitely To deal with this problem, each message is given a timestamp, and if the timestamp of a received message is older than some cutoff, the message is discarded All messages recorded in the received-messages relation that are older than the cutoff can be deleted

We can characterize the response of a circuit in the following way Let E be a phasor that represents a source or excitation of the circuit It may be a voltage or a current Now let R be the response of the circuit Then R = HE (814)

We show here how some of the concurrency-control schemes discussed in 16 can be modi ed so that they can be used in a distributed environment We assume that each site participates in the execution of a commit protocol to ensure global transaction atomicity The protocols we describe in this section require updates to be done on all replicas of a data item If any site containing a replica of a data item has failed, updates to the data item cannot be processed In Section 196 we describe protocols that can continue transaction processing even if some sites or links have failed, thereby providing high availability

The various locking protocols described in 16 can be used in a distributed environment The only change that needs to be incorporated is in the way the lock manager deals with replicated data We present several possible schemes that are applicable to an environment where data can be replicated in several sites As in 16, we shall assume the existence of the shared and exclusive lock modes
