Microsoft Message Queuing Services (MSMQs)

Microsoft Message Queuing Services (MSMQs) is a vital messaging infrastructure and a development tool for creating distributed, loosely-coupled, messaging applications for the Windows operating system. The OPERA Electronic Distribution Suite (OEDS) sends messages to these queues, which act as temporary storage locations used to ensure that messages reach their destination.

Message Queuing allows the OEDS software to communicate across heterogeneous networks and with computers that may be off-line, and provides guaranteed message delivery, efficient routing, security, transactional support, and priority-based messaging.

Note: This topic is geared towards Microsoft Windows 2000.

OEDS-Related Message Queues

By default, all OEDS-related message queues are created as Private Queues, and the Everyone User is assigned the Full Control permission. This occurs during the installation process.

Clearing OEDS- Related Message Queues

Important Note: OEDS-related message queues must be cleared prior to performing an upgrade installation. If you are performing a new installation, see Installing Message Queuing Services.

To clear the OEDS-related message queues, follow these steps:

  1. Right-click on the My Computer icon and select Manage.
  2. In the Computer Management window, expand the Services and Applications, Message Queueing, and Private Queues directories.

    Note: By default, all OEDS-related message queues are created as private queues.

  3. Further expand all of the OEDS-related private queues, as shown below.

  4. In the expanded Private Queue directory, right-click on each queue and select All Tasks>Purge.
  5. The MSMQ Admin prompts, "Are you sure you want to delete all messages in the queue?". Select the Yes button.
  6. Repeat these steps until all OEDS-related queues are cleared.
