RAC Specific Background Processes:
LMS : Lock Monitor Service ( Global Cache Service )
* it is responsible for transferring the blocks whenever needed by node,
* it is helpful in cache fusion.
LMON : Lock Monitor Process ( Global Enque service )
* Lmon will monitor the mechanism of LMD.
* it is responsible for reconfiguration of local resources whenever an instances joins or leaves the cluster.
* Responsible for dynamic remastering.
LMD : Lock Monitor Daemon ( Global Enque Service )
* LMD will do the locking on blocks.
* this daemon handles dead lock detections and remote enque request.
Lck : Lock Process :
* it manages requests that are related to shared pool ( library cache and data dictinary cache ).
* it manages non-cache fusion data.
* it shares the parsing data.
DIAG: Diagnosability Daemon
*Monitors the health of the instance and captures the data for instance process failures.
Note : i have given information RAC specific background processes,which process what do's,
