Nuovi processi di background in 11g

Oracle 10g accustomed us to a proliferation of background processes, especially with regard to the RAC, but breaks all 11g and introduces a number of processes dedicated to the tasks most imaginative:

DBRM (database resource manager) tax the resources of the Resource Manager

DIA0 (diagnosability process) solves the deadlock and detects blocks

EMNC (Event monitor coordinator) manages events and alerts

FBDA (flashback data archiver process) archives the historical data table that is activated and maintains the archive archive flashbak

GTX0

-j (global transaction ) allows global transactions

distributed (XA) in RAC environment. Currently XA transactions are only possible on a single node for client

• gmon manages the disks in the ASM diskgroup


• KATE handles the I / O ASM a disk that went offline for some reason


• MARK brand as invalid allocation units scritte su dischi ASM che sono andati offline


• SMCO (space management coordinator) gestisce l'allocazione e la deallocazione dello spazio su disco in maniera proattiva


• VKTM (virtual keeper of time) mantiene l'orologio di riferimento, che viene aggiornato ogni secondo
Col tempo ci sarà occasione di approfondire i compiti dei nuovi processi.
