# TIBCO® Metadata Agents

## Overview

In the Metadata Administration perspective select Agents to access the list of your registered Metadata Agents.

By default, only active Metadata Agents are visible. If you want to see the inactive Metadata Agents, go to the View menu and switch to Deactivated TIBCO Metadata Agents.

The records in this table are created and updated automatically when a Metadata Agent starts and contacts Metadata to subscribe or check that the subscription is up-to-date.

If an agent is not available, it will appear in red. On mouse over, the reason of the unavailability is displayed.

## Metadata Agent registration

When a Metadata Agent subscribes to the EBX® Metadata Management application the following elements are created in the Agents table:

Module name | Description
--- | ---
GUID | The GUID generated by the EBX® Metadata Management application for the Agent during the subscription.
Label | A label that will be used to present Metadata Agents in user interactions.
Base URL | Agent’s base URL.
Agent API Version | REST API version of this agent. This defines a list of the operations available.
Timezone | Agent’s timezone that will be used to convert dates for scheduled jobs.
JWT | JSON Web Token corresponding to the technical user with which Metadata Agent connects to the EBX® Metadata Management application. See Technical Users for more details.
Technical User Name | Technical user login. See Technical Users for more details.
Landing dataspace | Identifier of the dataspace that Metadata Agent uses to store raw metadata retrieved from TDV.
Destination Dataspace | Identifier of the target dataspace where the metadata will be integrated.
TDV JDBC URL | JDBC URL of the TDV system data source.
TDV Host | Host name where the TDV instance is situated.
TDV Port | Port number on which the TDV instance is listening for the JDBC connection.
TDV Version | TDV Version.
Published views folder | Path to the TDV published views folder. See Administration of TIBCO® Metadata Agent
Operations | List of the API operations available in Metadata Agent.

These elements are verified and updated if necessary each time the Metadata Agent instance is restarted.

On subscription, an instance corresponding to the TDV system data source is created in the EBX® Metadata Management application to allow harvesting of the published view available in TDV.

## Set Metadata Agent as favorite

Several Metadata Agents can be subscribed to the same EBX® Metadata Management application instance. In order to define one of them to be used in priority for the instances that are not yet linked to another agent, select the Select as favorite icon near Metadata Agent:

To change your favorite Metadata Agent select the Set as favorite icon for another Metadata Agent. You can only have one favorite agent.

## Disable Metadata Agent

To disable Metadata Agent and all related objects (Managed data sources, assets, links and introspection jobs), select the Disable icon near the Metadata Agent label.

This Metadata Agent will no longer be visible in your list of registered agents and it won’t be possible to run any operation with this agent. To see a disabled agent, go to the View menu and switch to Deactivated TIBCO Metadata Agents.

From this view, you can re-enable a Metadata Agent by clicking on the Enable button near it. However, the related managed objects won’t be re-enabled with the agent.

## Delete Metadata Agent

To delete permanently a Metadata Agent from the EBX® Metadata Management application, select this agent and select the Delete icon above the table:

Note: This operation cannot be undone. |

This operation will also delete related objects from the system:

- Managed data sources

- Managed assets

- Managed links

- Introspection Jobs and corresponding job executions history
