# Command-line option

If you have the authority to issue z/OS® operator commands, you can use the command-line interface to manage data collection for the Dataset Attributes Database feature as follows:

    F temsname,S3DA command_function

where temsname is the name of the Tivoli® Enterprise Monitoring Server started task and command_function is one of the following:

Command function | Purpose
--- | ---
`START` or `COLLECT` | Immediately start a collection cycle. Previously defined volume and storage group exclusion lists are used, if any exist.
`STATUS` | Display the current status of a Dataset Attributes Database collection cycle that is running.
`HALT` or `STOP` | Immediately stop an collection cycle. Attributes and reports for every data set are processed up to the point that the `STOP` command was issued are available for viewing from the Tivoli Enterprise Portal.
`TERM` | Terminate all processing for the Dataset Attributes Database feature.

You find messages and output from any of these commands in the RKLVLOG output from the Tivoli Enterprise Monitoring Server.
