Hi All, I need to start monitoring the rac services if they are on preferred or available instance for an issue we are having.before reinventing the wheel I wonder if somebody is doing something similar. I would really appreciate if you have a monitoring like this in place especially for nagios I wish Oracle add a column PREFERRED, AVAIABLE to gv$services and gv$active_services but this info can only be gathered from srvctl and it needs a lot of string manipulation which I am not too good to write it down within current time constraints Regards -- -- Coskan GUNDOGAR Oracle DBA Email: coskan@xxxxxxxxx Blog: http://coskan.wordpress.com Twitter: http://www.twitter.com/coskan Linkedin: http://uk.linkedin.com/in/coskan
