Question #: 43
Topic #: 11

You have a script with several CELLCLI commands that must be executed on each cell in your Exadata full rack. The script must run on each cell simultaneously. How must you achieve this?

ACopy and execute the script on all storage servers using the EXACLI command.

BCopy the script to all storage servers using the dcli command and manually execute it on all storage servers using the EXACLI command.

CCopy and execute the script on all storage servers using the dcli command.

DCopy the script to all storage servers using the dcli command and manually execute it on each storage server using the DCLI command.

ECopy the script to all storage servers using the CELLCLI command and execute it on all storage servers in parallel using the CELLCLI command.

Show Suggested Answer

Suggested Answer: C

According to Oracle's documentation1, the Cell Control Command-Line Interface (CellCLI) utility is the command-line administration tool for Oracle Exadata System Software. It can be used to perform various tasks on Exadata Storage Servers, such as creating and managing objects, monitoring performance, and configuring alerts.

To run CELLCLI commands on multiple cells simultaneously, you can use the Distributed Command-Line Interface (dcli) utility2. The dcli utility allows you to execute commands or scripts on a group of cells or hosts in parallel.You can use the dcli utility to copy files from one cell or host to multiple cells or hosts using the -f option3.You can also use the dcli utility to execute commands or scripts on multiple cells or hosts using the -l option to specify a user name and the -g option to specify a file containing a list of cells or hosts3.

Therefore, to achieve your requirement of running a script with several CELLCLI commands on each cell in your Exadata full rack simultaneously, you must:

Copy and execute the script on all storage servers using the dcli command.

I think Wilda is right, using CELLCLI for parallel execution seems like the best approach in this scenario.

But wouldn't it be more efficient to use dcli for this task?

I heard the Exadata cells have a secret mode where you can just yell the commands and they'll execute in parallel. Too bad they didn't include that as an option here.

Hmm, E looks like the most efficient option. Copying and executing the script in parallel using CELLCLI sounds like the way to go for a full rack.

I think option C is the way to go. Why bother with manual execution when you can just use dcli to copy and execute the script on all servers?
