# SyncImageHashes

Forces Media Server to synchronize its image hash training with the latest data in the database.

When you train Media Server, the database is updated with new training data. However, Media Server does not use this training in analysis operations until it has synchronized with the database.

TIP:

Media Server automatically synchronizes with the database before starting analysis, and at regular intervals. You only need to run this action if you have disabled automatic synchronization.

If you have disabled automatic synchronization but want your image hash analysis task to use the latest training, run `SyncImageHashes` and wait for synchronization to complete before starting the task with the Process action.

Type: synchronous

Parameter | Description | Required
--- | --- | ---
`database` | The name of the image hash database that you want Media Server to synchronize with. If you do not set this parameter, Media Server synchronizes with all image hash databases. | No

## Example
