Oracle documentation said :
Oracle Enterprise Manager
You can use Oracle Enterprise Manager to monitor the Oracle Clusterware environment. When you log in to Oracle Enterprise Manager using a client browser, the Cluster Database Home page appears where you can monitor the status of both Oracle Clusterware environments. Monitoring can include such things as:
++ Notification if there are any VIP relocations
++ Status of the Oracle Clusterware on each node of the cluster using information obtained through the Cluster Verification Utility (cluvfy)
++ Notification if node applications (nodeapps) start or stop
++ Notification of issues in the Oracle Clusterware alert log for the Oracle Cluster Registry, voting file issues (if any), and node evictions
but i do not know how ? or from which page?
any idea ?!
