The CellCLI utility supports command-line history.

Each Exadata Storage cell can be monitored, configured, and maintained using the cellcli command line interface.

The dcli utility facilitates centralized management across an Oracle Exadata Storage Server Software realm by automating the execution of CellCLI commands on a set of cells and returning the output to the centralized management location where the dcli utility was run.
