[CentOS] where is hangcheck-timer RPM on CENTOS 4.5

I am testing ORACLE RAC 9.2.0.8 and document say
"hangcheck-timer-XXX" should include in Redhat Advance
server.  When I installed CENTOS 4.5, I installed
"everything".  I can NOT find 'hangcheck-timer" RPM in
my system.  

can Anyone tell me where is "hangcheck-timer" RPM or
where can I download it?

Thanks.
