Show Suggested Answer

Suggested Answer: D

Exachk is an Oracle-provided diagnostic tool that allows you to check various components of an Exadata Database Server, including the client network. The tool is located in the /opt/oracle.SupportTools/exachk/ directory and can be run with the command: exachk. This command can be run with the option ---from <Fridays_Date>_17:00:00 and ---to <Sundays_Date>_23:59:00 to specify a time range of interest, this way you can check the client network status between the specified time range. The tool checks the status of various components such as network interfaces, InfiniBand fabric, and storage servers. It also analyzes log files, configuration files, and system settings to detect any issues. The tool generates a report, which can be used to identify the root cause of the issue and provide recommendations for resolution.

Tfact1 is a tool to collect diagnostic information from Exadata and non-Exadata systems and it is not related to client network status.

Netcheck and GetExaWatcherResults.sh are not tools provided with the Exadata Database Server and they are not related to client network status.

Hmm, I'm a bit confused about option E. Isn't patchmgr used for applying the actual updates? I think that should be a separate step after the preparation.

I think we should consult My Oracle Support note 888828.1 first.
