# Asynchronous Actions

By default, the Content component processes all actions synchronously. In this case, Content does not respond to the action until it has completed the request. The result of the action is in the response to the request.

With additional configuration, you can also process query actions asynchronously. In this case, Content responds to the action immediately. The request is added to a queue of actions. The response to the request contains a token. You can use this token to determine whether the request has finished, and obtain the results of the action. To do this, use the `QueueInfo` action.

You might want to use asynchronous actions to run operations that take a long time, and that do not require an immediate response. For example, you might have synchronous queries to return results to users, and then use an asynchronous action to run a query summary.

## Configure Asynchronous Actions

You must configure the Content component to allow asynchronous actions.

To configure asynchronous functionality

1. Open the Content component configuration file in a text editor.

2. Create an `[Actions]` configuration section.

3. In the `[Actions]` section, add the `Async` parameter, and set it to `AsyncActions`.

4. Create an `[AsyncActions]` section.

5. In the `[AsyncActions]` section, set the `Threads` parameter to the number of threads that you want to use for asynchronous actions.

6. Save and close the configuration file.

7. Restart the Content component for your changes to take effect.

For example:

    [Actions]
    Async=AsyncActions

    [AsyncActions]
    Threads=2

## Send Asynchronous Actions

To send an asynchronous action, you use the same action syntax as normal, but add the `Synchronous` parameter, set to `False`.

You can send the following actions asynchronously:

`DetectLanguage` | `GetTagValues` | `Summarize`
`DocumentStats` | `Highlight` | `TermExpand`
`GetAllRefs` | `List` | `TermGetAll`
`GetContent` | `Query` | `TermGetBest`
`GetQueryTagValues` | `Suggest` | `TermGetInfo`
`GetTagNames` | `SuggestOnText` |

## Retrieve Results for Asynchronous Actions

The `QueueInfo` action allows you to retrieve the status and results of asynchronous actions.

To return the results of all asynchronous actions, send a `QueueInfo` action, with the `QueueName` parameter set to `Async`, and the `QueueAction` parameter set to `GetStatus`. You can set the `Token` parameter to the token for a specific action to retrieve results for only that action.

NOTE: If you do not specify the `Token` parameter, all results for the server return. OpenText does not recommend that you return all results for a server that has been running for a long time, because the response might time out.

NOTE: There are no user restrictions for viewing the queue list, so all users can see all results that the original action returns. OpenText does not recommend that you use asynchronous actions if you have strict document security requirements.

TIP: You can use the `QueueInfo` action to return information about the queue, and to cancel or change the priority of actions. For more information, refer to the Content component Reference.

You can use the Asynchronous Queues page in the Monitor section of Knowledge Discovery Admin to view details of the asynchronous actions that the server is processing, view the results of those actions, and cancel actions. For more information, refer to the Knowledge Discovery Admin User Guide.
