The RBAL and ARBn processes are used only if you use Oracle s Automatic Storage Management. When you use ASM, you must create an ASM instance, and that instance will use these processes to perform disk storage management. The ASMB process acts as the mediator between your database (when you re using ASM-based disk storage) and the ASM instance. I discuss ASM in detail in 17.

The database writer, log writer, archiver, and checkpoint background processes are the most commonly referenced background processes. However, Oracle Database 11g can have many more background processes running to support an instance. I describe the most important of these background processes briefly here. The manageability monitor process collects several types of statistics to help the database manage itself, such as, for example, the AWR snapshot information, which is the basis for the performance diagnostics capability of the database. In addition, MMON issues alerts when database metrics violate their threshold values. The manageability monitor light process shows up as Manageability Monitor Process 2 when you query the V$BGPROCESS view. The process flushes data from the Active Session History (ASH) to disk whenever the buffer is full. The MMNL process also performs other manageability-related tasks, such as capturing session history data and computing database metrics. The memory manager process coordinates the sizing of the memory components. Oracle uses the job queue coordination process to schedule and run user jobs. The CJQO process dynamically spawns job queue slave processes (J000 through J999), which run the user jobs. When you enable the flashback database feature (which I explain in 16), Oracle starts the recovery writer (RVWR) process to write the flashback data from the flashback buffer to the flashback logs. In a sense, the RVWR S job is analogous to that of the LGWR background process. Oracle tracks the physical location of database changes in a new file called the change-tracking file. Oracle s backup utility, the Recovery Manager, uses the change-tracking file to determine which data blocks to read during an incremental backup, making the incremental backups faster by avoiding reading entire datafiles. The change-tracking writer (CTWR) process is the new Oracle background process that writes change information to the change-tracking file. You ll learn more about the CTWR process in 15, which discusses database backups. The recoverer (RECO) process is used to coordinate distributed databases and other specialized processes.

Note Besides the processes discussed here, other Oracle background processes that perform specialized tasks may be running in your system. For example, if you use Oracle Real Application Clusters, you ll see a background process called the lock (LCKn) process, which is responsible for performing interinstance locking.

The flashback data archiver (FBDA) process is in charge of writing changes to tables that are enabled for the flashback data archive into the history tables. The result cache background (RCBG) process is in charge of the result cache management. You can view all available Oracle background processes by querying the V$BGPROCESS view.

Oracle uses a part of its memory allocation to hold both program code and data, which makes processing much faster than if it had to fetch data from the disks constantly. These memory structures enable Oracle to share executable code among several users without having to go through all the preexecution processing every time a user invokes a piece of code. The Oracle server doesn t always write changes to disk directly. It writes database changes to the memory area, and when it s convenient, it writes the changes to disk. Because accessing memory is many times faster than accessing physical disks (memory access is measured in nanoseconds, whereas disk access is measured in milliseconds), Oracle is able to overcome the I/O limitations of the disk system. The more your database performs its work in memory rather than in the physical disk storage system, the faster the response will be. Of course, as physical I/O decreases, CPU usage will also decrease, thus leading to a more efficient system.
