# JMS Templates: Configuration: Override

Configuration Options Related Tasks Related Topics

Destinations can override some of the settings (such as priority) that the message producer includes with its messages. Use this page to configure such overrides for destinations that are based on this template.

As with all template options, settings in individual destinations supersede template settings.

#### Configuration Options

Name | Description
--- | ---
Priority Override | The priority assigned to all messages that arrive at the destination, regardless of the Priority specified by the message producer. The default value (-1) specifies that the destination will not override the Priority set by the message producer. Note: This attribute is dynamically configurable, but only incoming messages are impacted; stored messages are not impacted. MBean Attribute (Does not apply to application modules): `DeliveryParamsOverridesBean.Priority` Minimum value: `-1` Maximum value: `9`
Time-to-Live Override | The time-to-live assigned to all messages that arrive at this topic, regardless of the TimeToLive value specified by the message producer. The default value (`-1`) specifies that this setting will not override the TimeToLive setting specified by the message producer. Range of Values: Between 0 and a positive 64-bit integer. Note: This attribute is dynamically configurable, but only incoming messages are impacted; stored messages are not impacted. MBean Attribute (Does not apply to application modules): `DeliveryParamsOverridesBean.TimeToLive` Minimum value: `-1` Maximum value: `9223372036854775807`
Time-to-Deliver Override | The default delay, either in milliseconds or as a schedule, between when a message is produced and when it is made visible on its target destination, regardless of the delivery time specified by the producer and/or connection factory. The default value (`-1`) specifies that the destination will not override the TimeToDeliver setting specified by the producer and/or connection factory. The TimeToDeliver override can be specified either as a long or as a schedule. Note: Changing the TimeToDeliver override only affects future message delivery, it does not affect message delivery of already produced messages. MBean Attribute (Does not apply to application modules): `DeliveryParamsOverridesBean.TimeToDeliver`
Delivery Mode Override | The delivery mode assigned to all messages that arrive at the destination regardless of the DeliveryMode specified by the message producer. A value of `No-Delivery` specifies that the DeliveryMode will not be overridden. Note: This attribute is dynamically configurable, but only incoming messages are impacted; stored messages are not impacted. MBean Attribute (Does not apply to application modules): `DeliveryParamsOverridesBean.DeliveryMode`
