String message specifies the message as a string. When receiving messages, you can configure the task to save the file, overwrite an existing file, and specify the package from which the task can receive messages. You can configure the message types that the Message Queue task provides in the following ways:ĭata file message specifies that a file contains the message. If the Message Queue task does not use encryption, the task can run successfully. The Message Queue task fails to comply with Federal Information Processing Standard (FIPS) 140-2 when the computer's operating system is configured in FIPS mode and the task uses encryption. For more information about installing and running the Message Queue task, see Install Integration Services. To ensure a complete installation of Integration Services, you must select Integration Services on the Components to Install page. For example, the SQL Server Data Tools (SSDT) option installs the Integration Services components required to design a package, but the Integration Services service is not installed, and therefore the Message Queue task is not functional. These components are useful for specific tasks, but the functionality of Integration Services will be limited. Some SQL Server components that you may select for installation on the Components to Install page or the Feature Selection page of the SQL Server Installation Wizard install a partial subset of Integration Services components. The Message Queue task requires that the Integration Services service be installed. For more information about Message Queuing, see the MSDN Library. For more information, see MSMQ Connection Manager. The task uses an MSMQ connection manager to connect to a message queue. The string message to variable message type can be used only when receiving messages. When sending or receiving messages, the Message Queue task uses one of four message types: data file, string, string message to variable, or variable. A package running on the destination computer then uses a Message Queue task to retrieve and save the package locally. For example, a package can use a Message Queue task to send a package file to another computer. For example, the output from a restaurant cash register can be sent in a data file message to the corporate payroll system, where data about each waiter's tips is extracted.ĭistributing files throughout your enterprise. Sending data files to the computer that processes them. After all the sites have checked in, the package computes summary totals. When a message from a site arrives, a task uploads data from that site. A package running on the corporate computer contains Message Queue tasks, each waiting for a message from a particular retail site. For example, after nightly maintenance at each of your retail sites, a Message Queue task sends a message to your corporate computer. You can use the Message Queue task for the following purposes:ĭelaying task execution until other packages check in. Messages can be queued and delivered later if the destination is unavailable or busy for example, the task can queue messages for the offline laptop computer of sales representatives, who receive their messages when they connect to the network. These messages can take the form of simple text, files, or variables and their values.īy using the Message Queue task, you can coordinate operations throughout your enterprise. The Message Queue task allows you to use Message Queuing (also known as MSMQ) to send and receive messages between SQL Server Integration Services packages, or to send messages to an application queue that is processed by a custom application.
