background processes in Oracle 11g

Oracle 11g Tips by Burleson Consulting


Jeremiah Wilton (OCM) shares this list of the new background processes in Oracle 11g:

VKTM - The virtual keeper of time provides wall-clock time and reference time for other sessions/processes.

FBAR :-) - (sadly now renamed to FBDA partway through the beta) The flashback data archiver writes old row-versions of tables with 'flashback archive' enabled into flashback data archives on commit. Anyone remember Oracle v.5 BIFs?

DIAG - The diagnosibility process (DIAG) runs oradebug commands and triggers diagnostic dumps as part of the new ADR (automatic diagnostic repository) feature, which is a replacement (and major enhancement) for the much-reviled RDA.

DIA0 - The "other" diagnosibility process detects hangs then triggers DIAG do take diagnostics.

SMCO/Wnnn - The space management coordinator and slaves perform space allocation and reclamation.
