# Configure diagnostic archives

Each server in a domain persists (archives) all events, log records, and harvested metrics collected by the WebLogic Diagnostic Framework. Log files are archived as human-readable files. Events and harvested data are archived in binary format, in a Weblogic persistent store or in a database.

To configure settings for a diagnostic archive:

1. If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
2. In the left pane, expand Diagnostics and select Archives.
3. On the Summary of Diagnostic Archives page, click the name of the server for which you want to configure diagnostic archive settings.
4. Select one of the following archive types from the Type list:
   - Select File Store to persist data to the file system. If you choose this option, enter the directory in the Directory field. The default directory is the `data/store/diagnostics` directory under the home directory of the server.
   - Select JDBC to persist data to a database. If you choose this option, select the JDBC data source from the Data Source list. You must first configure JDBC connectivity to use this option. See Configure database connectivity.
5. Click Save.
6. To activate these changes, in the Change Center of the Administration Console, click Activate Changes.
   Not all changes take effect immediately—some require a restart (see Use the Change Center).
