# JMS Template --> Configuration --> Override

Tasks Related Topics Attributes

## Overview

This tab defines configuration override attributes for a JMS template, which provides an efficient means of defining multiple destinations with similar attribute settings.

The configurable override attributes for a JMS template are the same as those configured for a destination. However, if the destination that is using a JMS template specifies an override value for an attribute, the override value is used.

## Attributes

Table 22-1

Attribute Label | Description | Value Constraints
--- | --- | ---
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 setting. This attribute is dynamically configurable, but only incoming messages are impacted; stored messages are not impacted. MBean: `weblogic.management. configuration. JMSTemplateMBean` Attribute: `PriorityOverride` | Minimum: -1 Maximum: 9 Default: -1 Dynamic: yes
Time To Live Override | The time-to-live value assigned to all messages that arrive at the destination, regardless of the TimeToLive specified by the message producer. The default value (-1) specifies that the destination will not override the TimeToLive setting. This attribute is dynamically configurable, but only incoming messages are impacted; stored messages are not impacted. MBean: `weblogic.management. configuration. JMSTemplateMBean` Attribute: `TimeToLiveOverride` | Minimum: -1 Maximum: 9223372036854775807 Default: -1 Dynamic: yes
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 TimeToDeliver specified by the producer and/or the connection factory. The default value (-1) specifies that the destination will not override the TimeToDeliver setting. The Time To Deliver Override can be specified either as a `long` or as an advanced scheduling syntax (see "Setting Message Delivery Times" in Programming JMS for details.) Note: Changing the Time To Deliver Override only affects future message delivery, it does not affect message delivery of already produced messages. MBean: `weblogic.management. configuration. JMSTemplateMBean` Attribute: `TimeToDeliverOverride` | Default: "-1" Dynamic: yes
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. This attribute is dynamically configurable, but only incoming messages are impacted; stored messages are not impacted. MBean: `weblogic.management. configuration. JMSTemplateMBean` Attribute: `DeliveryModeOverride` | Default: No-Delivery Valid values: Persistent Non-Persistent No-Delivery Dynamic: yes
