# JobExecutionSettings


Makes it possible to control how your transcription job is processed. Currently, the only `JobExecutionSettings` modification you can choose is enabling job queueing using the `AllowDeferredExecution` sub-parameter.

If you include `JobExecutionSettings` in your request, you must also include the sub-parameters: `AllowDeferredExecution` and `DataAccessRoleArn`.

## Contents


 ** AllowDeferredExecution **   <a name="transcribe-Type-JobExecutionSettings-AllowDeferredExecution"></a>
Makes it possible to enable job queuing when your concurrent request limit is exceeded. When `AllowDeferredExecution` is set to `true`, transcription job requests are placed in a queue until the number of jobs falls below the concurrent request limit. If `AllowDeferredExecution` is set to `false` and the number of transcription job requests exceed the concurrent request limit, you get a `LimitExceededException` error.  
If you include `AllowDeferredExecution` in your request, you must also include `DataAccessRoleArn`.  
Type: Boolean  
Required: No

 ** DataAccessRoleArn **   <a name="transcribe-Type-JobExecutionSettings-DataAccessRoleArn"></a>
The Amazon Resource Name (ARN) of an IAM role that has permissions to access the Amazon S3 bucket that contains your input files. If the role that you specify doesn’t have the appropriate permissions to access the specified Amazon S3 location, your request fails.  
IAM role ARNs have the format `arn:partition:iam::account:role/role-name-with-path`. For example: `arn:aws:iam::111122223333:role/Admin`. For more information, see [IAM ARNs](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_identifiers.html#identifiers-arns).  
Note that if you include `DataAccessRoleArn` in your request, you must also include `AllowDeferredExecution`.  
Type: String
