# JMS Topic: Configuration: Overrides

Configuration Options Related Tasks Related Topics

Destinations can override some of the settings (such as priority) that a message producer includes with its messages. Use this page to configure such overrides for this topic.

You configure topics explicitly or by configuring a JMS template to define and manage multiple topics with similar attribute 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`
