MZnn is a dedicated process for a single MMON slave action. The background processes of the Oracle instance manage memory structures, asynchronously perform I/O to write data to a file on a disk, and perform general maintenance tasks. The ASM RBAL background process coordinates and spawns one or more of these slave processes to recover aborted ASM transactional operations. LGWR cannot reuse and overwrite an online redo log group until it has been archived. It works with the instant recovery feature to ensure immediate data file access. The local instance has immediate access to the remote snapshot file's data, while repopulation of the recovered primary data files happens concurrently. FENC receives and processes the fence request from CSSD. ORA-00443 You May Computes dependencies between logical change records (LCRs) and assembles messages into transactions (Reader Server), Applies LCRs to database objects or passes LCRs and user messages to their appropriate apply handlers (Apply Server). The process schedules managed processes in accordance with an active resource plan. The LSP2 process is created as needed during startup of SQL Apply to update the list of objects that are protected by the database guard. LSP0 is also responsible for detecting and enabling run-time parameter changes for the SQL Apply product as a whole. Provides transparent support for XA global transactions in an Oracle RAC environment. The dispatcher slave processes enable scaling of Direct NFS connections to a clustered NAS storage. Monitors an Oracle RAC cluster to manage global resources. VKTM publishes two sets of time: a wall clock time using a seconds interval and a higher resolution time (which is not wall clock time) for interval measurements. Database instances, Oracle ASM instances, Oracle RAC, Performs required tasks including SQL and DML, Database instances, Oracle ASM instances, Oracle ASM Proxy instances, Monitors all mounted Oracle ASM disk groups. The possible processes are SCR0-SCR9. Initiates background population and repopulation of in-memory enabled objects. CSnn slave processes are started on execution of the DBMS_RESOURCE_MANAGER.CALIBRATE_IO() procedure. The propagation receiver passes the LCRs to an apply process. Emulates I/O errors on Oracle ASM disks through named events. 6 Oracle Background Processes Every Good DBA Needs To Know. LDDn processes are slave processes spawned on demand by LMDn processes. Relays messages between Oracle ASM instance and Oracle ASM Proxy instance that is used by ADVM (for ACFS), Performs various background space management tasks, including proactive space allocation and space reclamation. SCVn acts as a slave process for SCRB and performs the verifying operations. Coordinates Oracle ASM disk scrubbing operations. For GoldenGate Integrated Replicat, query V$GG_APPLY_SERVER. These background processes are spawned or reused during the start of a parallel statement. This relationship is maintained until the master requires services of a particular service process. Spawns Oracle background processes after initial instance startup.
