OCF Scripts are programs on the HA system. Heartbeat runs these scripts periodically to get status updates or to start or stop resources. It places certain named values in environment variables that the OCF script then uses to know which instance of the resource it is supposed to be starting/stopping/monitoring. > 2.

You configure Heartbeat, which then calls the OCF script with the parameters you define. The OCF script expects certain parameters to be defined, and tells you which ones it expects through the meta-data inside the script (if you run an OCF script on the command line with the command meta-data it will provide this meta-data to you). For example: to configure a Filesystem resource, you would provide name-value pairs for "device", "directory", "fstype" (which is optional) and "options" (which is also optional). > > On Thu, Mar 18, 2010 at 12:45 PM, Marian Marinov <[email protected]> wrote: > >> Hello, >> you should read this: >> hnak >> http://www.opencf.org/cgi-bin/viewcvs.cgi/specs/ra/resource-agent- >> api.txt?rev=HEAD&content-type=text/vnd.viewcvs-markup<http://www.opencf.org/cgi-bin/viewcvs.cgi/specs/ra/resource-agent-%0Aapi.txt?rev=HEAD&content-type=text/vnd.viewcvs-markup> >> >> Regards, >> Marian >> >> On Thursday 18 March 2010 07:34:17 Umakant Goyal wrote: >>> Hi All, >>> >>> Can someone give me the idea how to write OCF (Open Cluster Framework) >>> script to monitor running process in the system and provide the status of >>> the same to the HeartBeat? >>> >>> Thanks in Advance >>> _______________________________________________ >>> Linux-HA mailing list >>> [email protected] >>> http://lists.linux-ha.org/mailman/listinfo/linux-ha >>> See also: http://linux-ha.org/ReportingProblems >>> >> -- >> Best regards, >> Marian Marinov >> >> _______________________________________________ >> Linux-HA mailing list >> [email protected] >> http://lists.linux-ha.org/mailman/listinfo/linux-ha >> See also: http://linux-ha.org/ReportingProblems >> > _______________________________________________ > Linux-HA mailing list > [email protected] > http://lists.linux-ha.org/mailman/listinfo/linux-ha > See also: http://linux-ha.org/ReportingProblems > Regards, Adrian Overbury _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
