##Viewing Alert Logs in Oracle Cloud Infrastructure (OCI) for Oracle Autonomous Databases

### Limited OS Access

For Oracle Autonomous Databases, direct access to the underlying operating system is restricted. Therefore, alert log monitoring must be done through SQL views and the OCI Console.

### SQL-Based Alert Log Access

#### Deprecated View

- **`V$DIAG_ALERT_EXT`**: Previously used to query alert logs directly via SQL.

- **Status**: **Removed** in recent Oracle ADB updates.

#### Replacement View

- **`V$CLIENT_ERRORS`**: Introduced as the new method to access alert log-related error data.

- **Purpose**: Displays XML-based error logs, including client connection issues and user errors like `ORA-4021`.

### Current Limitations of `V$CLIENT_ERRORS`

- **Session Dependency**: The view only shows error data **while the session is active**.

- **Post-Session Visibility**: If a session is terminated (e.g., killed due to resource limits), its error data **is no longer visible** in the view.

- **User Experience**: This behavior is understandably frustrating, as it limits post-mortem diagnostics.

### Enhancement in Progress

Oracle is actively working on enhancing `V$CLIENT_ERRORS` to improve its usability and persistence of error data beyond session lifetime. No official release date has been announced yet, but updates are expected soon.
