Global transaction

Whether or not a global transaction is started for each message processed.

Cleared

A global transaction is started for each message processed.
Required No

Allow concurrent mediation

Select this option (setting it to true) to apply the mediation to multiple messages concurrently. Message ordering is not preserved. The default option is false.

Selected
Apply the mediation to multiple messages concurrently, and preserve message ordering.
Cleared
Apply the mediation to a single message at a time. This setting is required to ensure that message ordering is preserved.
Required No
Data type Check box
Default Cleared

Selector

Controls which messages are sent to the mediation. If a message matches the rule defined by the selector text string, then the mediation is applied to the message.

If the message does not match the rule defined by the selector text string, then the message is not mediated. If a message contains both Selector and Discriminator, it must match both rules for the message to be mediated. If either the Selector or the Discriminator rule does not match, the message is not mediated.

You should base the content of the selector text string on an understanding of which messages should be processed by the mediation. The format of the selector string is the same as for JMS selectors.

Required No
Data type Text
Default Cleared

Discriminator

Controls which messages have the mediation applied to them. If the topic of a message matches the rule specified by the discriminator text string, then the mediation is applied to the message. If both the selector and discriminator are specified, the message must match both rules for the mediation to be applied to the message.

Compare this property with the Selector property. The rule specified by the Selector examines the header and properties of the message, while the discriminator examines the topic of the message. If a message contains both Selector and Discriminator, it must match both rules for the message to be mediated. If either the Selector or the Discriminator rule does not match, the message is not mediated.

You should base the content of the discriminator text string on an understanding of which message topics should be processed by the mediation. The format of the discriminator is the same as the topic discriminator specification.

Required No

Default Cleared
