Introduction to QAnywhere messages

QAnywhere messages consist of the following parts:

Message properties can be referenced in transmission rules and delete rules or in your application.

The following sections describe message headers and properties, and how you can set them in QAnywhere messages.

  • Message headers, message properties, and message content cannot be altered after the message is sent.
  • You can read message headers, message properties, and message content after a message is received. If you are using the QAnywhere SQL API, these become unreadable after a commit or rollback occurs.
  • The content is unreadable after acknowledgement or commit in all APIs.
