Question

Options

• AThere is one ologgered service for the cluster health monitor (CHM) on each cluster node
• BThe Grid Infrastructure Management Repository database must run on a hub node if Flex
• CThere is one osysmond service for the cluster health monitor (CHM) on each cluster node
• DThe oclumon utility may be used to get and set parameters for the cluster health monitor (CHM)
• EThe diagcollection.pl script must be run from the Grid home directory as the Grid infrastructure

Explanation

B: The Oracle Grid Infrastructure Management Repository Runs on one node in the cluster.This must be a Hub Node in an Oracle Flex Cluster configuration. C: There is one system monitor service on every node. The system monitor service (osysmond) is a real-time, monitoring and operating system metric collection service that sends the data to the cluster logger service. D: Use the oclumon manage command to view and change configuration information from the system monitor service. oclumon manage -repos {{changeretentiontime time} | {changerepossize memory_size}} | -get {key1 [key2 ...] | alllogger [-details] | mylogger [-details]} Where changerepossize memory_size: Use this option to change the CHM repository space limit to a specified number of MB. Note: The OCLUMON command-line tool is included with CHM and you can use it to query the CHM repository to display node-specific metrics for a specified time period. You can also use OCLUMON to perform miscellaneous administrative tasks, such as changing the debug levels, querying the version of CHM, and changing the metrics database size. Incorrect Answers: E: You can collect CHM data from any node in the cluster by running the Grid_home/bin/diagcollection.pl script on the node. https://docs.oracle.com/database/121/CWADD/troubleshoot.htm#CHDIGCEC
