A data structure has been serialized when it has broken down into a sequence of bytes, often called octets. Serialized data are suitable for transmission through various means. A serialized connection is one that transfers serialized data. Some serialized connections, like streams and pipes, typically transfer data one octet at a time. Other connections, particularly those that use physical wires and cable, transfer data one bit at a time. Examples of such bit-oriented connections are network, modem, and USB connections. Serialized connections represent the most common type of shared resource used to send notifications. Considering connections as shared resources might seem strange, but it makes sense if you consider the fact that the sender writes data on one side, and the receiver reads data from the other, as shown in Figure 3-14.

RMAN executable: This is the actual program that manages all backup and recovery operations You can find the RMAN executable (also known simply as rman) in the $ORACLE_HOME/bin directory You specify the backup or recovery operation, and the RMAN executable performs it for you by interacting with the target database It records the results in the control file and the optional recovery catalog..

Server processes: These are the background processes that facilitate communication between the RMAN executable and the target database. The server process performs the real work of reading and writing to disk devices and tape drives during backup and recovery.

Figure 3-14 A serialized connection as a shared resource A serialized connection can be considered a queue, with the sender adding data at one end and the receiver removing data concurrently at the other This model abstracts away all the physical transmission characteristics of the connection However, there are two important things you should always keep in mind about serialized connections: 1 Connections might not be reliable 2 The transmission latency might be unpredictable If the sender and receiver are processes running in the same box, communicating over a pipe is fairly reliable Just keep in mind that reliable does not mean infallible You should consider connections unreliable if the sender and receiver are not physically packaged together For example, if the sender and receiver are in different countries and communicate over an Internet connection, the connection is probably not going to be extremely reliable.

Three entities are optional when you use RMAN: the flash recovery area, the recovery catalog database (and the recovery catalog schema), and media management software.

You have a choice of two locations for storing the RMAN repository: you can let RMAN store it in the target database control file, or you can configure and use the optional recovery catalog to manage the metadata The RMAN repository contains information about the following items: Datafile backup sets and copies Archived redo log copies and backup sets Tablespaces and datafile information Stored scripts and RMAN configuration settings By default, RMAN stores all metadata in the control file All RMAN information is first written in the control file, and then to the recovery catalog if one exists For instance, when RMAN creates a new backup set, you can view the information in the V$BACKUP_SET view You can also view the same information in the recovery catalog view, RC_BACKUP_SET.

Thus, for every change to the RMAN repository, information is recorded in two places: the control file and the optional recovery catalog The recovery catalog versions of the RMAN repository are stored in database tables The control file version of the repository is stored as records within the control file If you wish, you can manage the RMAN with just the information in the control file The objections you ll hear regarding using the recovery catalog are that it s too complex to maintain and that it needs another database to manage it However, there are some RMAN commands you can use only when you use the recovery catalog You can also use RMAN-stored scripts only if you use the recovery catalog If you use the control file, you run the risk of some of the historical data being overwritten, but the recovery catalog will safeguard all such data.
