Hangcheck Timer Not Needed for 11gR2 RAC


Hangcheck Timer FAQ (Doc ID 232355.1)

Do I need the hangcheck-timer with 11gR2 ?

Answer
-----------
The hangcheck-timer is not needed with 11gR2. This is documented in 'Oracle® Grid Infrastructure Installation Guide 11g Release 2 (11.2) for Linux' section 'Improved Input/Output Fencing Processes'.



Improved Input/Output Fencing Processes

Oracle Clusterware 11g release 2 (11.2) replaces the oprocd and Hangcheck processes with the cluster synchronization service daemon Agent and Monitor to provide more accurate recognition of hangs and to avoid false termination.
