See Also: Oracle Database Concepts and Oracle Database Administrator's Guide. LGWR workers are not used when there is a SYNC standby destination. An Oracle Database background process is defined as any process that is listed in V$PROCESS and has a non-null value in the PNAME column. For Oracle Database Appliance only, in the event of a instance crash, the surviving instance will recover the dead instance's database flash cache. SCCn acts as a slave process for SCRB and performs the checking operations. See Also: Oracle Real Application Clusters Administration and Deployment Guide, Serves as an I/O slave process spawned on behalf of DBWR, LGWR, or an RMAN backup session. Also, the processes help perform two-phase commit for global transactions anywhere in the cluster so that an Oracle RAC database behaves as a single system to the externally coordinated distributed transactions. When a connection becomes active, the connection broker hands off the connection to a compatible pooled server process. Initiates background population and repopulation of in-memory enabled objects. If the database has a multiplexed redo log, then LGWR writes the redo log entries to a group of redo log files. Initiates automation tasks involved in managing Exadata storage. See Also: Oracle Database Backup and Recovery User's Guide, Tracks the cluster membership in CSS and informs the file system driver of membership changes. Unnn processes are database container operating system processes where database backgrounds processes like SMON, CJQ0, and database foreground processes run. This background process thread is available only on Linux systems. Database instances, Oracle ASM instances, Oracle RAC, Schedules transactions for Data Guard SQL Apply. The names for CRnn processes will have the format CR0n__. Manages several background processes including shared servers, pooled servers, and job queue processes, connection broker and pooled server processes for database resident connection pools, Scans for dead processes and coordinates cleanup. In Windows, these run as separate threads within the same service. The process handles all requests for resources other than data blocks. Ships redo from current online and standby redo logs to remote standby destinations configured for ASYNC transport. 3.Checkpoint Process. The process terminates itself after being idle for a long time. Executes jobs assigned by the job coordinator. For XStream Inbound servers, query V$XSTREAM_APPLY_SERVER. In RAC, the various ARCH processes can be utilized to ensure that copies of the archived redo logs for each instance are available to the other instances in the RAC setup should they be .

Common background server for basic messaging and RDMA primitives based on IPC (Inter-process communication) methods. The propagation sender process name is CXnn, where nn can include letters and numbers. JPn patches and updates the Java in the database classes. Note that if the AQ_TM_PROCESSES initialization parameter is set to 0, this process will not start. The GLOBAL_TXN_PROCESSES initialization parameter specifies the number of GTXn processes, where n is 0-9 or a-j. If an apply server cannot resolve an error, then it rolls back the transaction and places the entire transaction, including all of its messages, in the error queue. You can disable these processes by setting the parameter to 0.
