Description
Bottom rule

WebSphere MQ Low Latency Messaging offers a reliable, high-speed, high-throughput transport for a broad range of messages in the front-, middle-, and back-offices of financial markets, and for other industries with similar needs. New capabilities now available in WebSphere MQ Low Latency Messaging V2.3 include:

Intelligent self-management through a centralized topic mapping service

Intelligent self-management is offered through a topic mapping service. This service can automatically configure topics to help make it easier for developers to create applications that can take advantage of Low Latency Messaging capabilities.

  • The topic mapping service allows for centralized management of topic mapping rules. This lets application developers create low-latency messaging topics without requiring them to understand low-level transport topic configuration parameters.
  • Applications that are configured to use the topic mapping service do not have to explicitly call low-latency messaging topic configuration APIs, but instead these operations are taken care of automatically by the service.
  • Parameters that can be centrally managed include the destination IP address, port number, and repair port number.

Ability to specify number of acknowledgments for multicast reliability, or Wait-N ACK support

With Wait-N ACK support, a Reliable Multicast Messaging (RMM) transmitter must receive an acknowledgement (ACK) for a packet from a specified number ("n") of different receivers before it can remove the packet from the stream's history queue. This is an extension of the previously supported Wait-1 ACK single acknowledgement offered in Low Latency Messaging.

  • Wait-N ACK support introduces the concept of mandatory acknowledgers so that acknowledgement can be required from specified critical receivers. Also included is receiver control of acknowledgements, which allows a receiver to modify whether it acknowledges messages or not, to help ensure that important messages are not acknowledged by unimportant applications.
  • Wait-N ACK support offers significant benefits to critical applications when used in conjunction with Low Latency Message Store by allowing a customer to specify that a message not be dropped from the queue until it is acknowledged that the message store or other key applications have received the message.

Positive acknowledgement feedback notification for transmitting applications

This feature gives an application the ability to know when a message that it has sent is positively acknowledged, either asynchronously or synchronously. This increases the range of control that the application can have over feedback notifications. Previously, such control was within the low-latency messaging transport, whereas now the application itself can control the notifications.

  • Both asynchronous and synchronous modes are supported.
    • In the asynchronous mode the application submits a message and can later check to determine if the message is acknowledged.
    • In the synchronous mode the application submits a message and does not complete the submit call until the message is acknowledged.
  • In addition, a fast ACK notification topic parameter is now added to avoid potential delays with synchronous ACK notification. By default an RMM receiver does not ACK every packet since this is likely to create a high load on the network and the RMM sender. However, with synchronous ACK notification this can be a problem because it may result in a long delay before the sender is able to send another message. The new fast ACK notification topic parameter can provide faster ACK notification to reduce this delay.

Message store assured delivery

Assured delivery is an enhancement to the Low Latency Message Store that was announced in Low Latency Messaging V2.2. This enhancement allows a transmitting or receiving application to confirm that a message is written to disk or other nonvolatile storage. With this new capability, Low Latency Messaging can provide a store and forward form of assured persistence with high performance.

  • Previously, messages transmitted were sent to the message store at the same time as they were sent to other receivers. So an application sending or receiving the data did not have the ability to determine whether or not a message had been written to disk before sending or requesting the data.
  • Now, with message store assured delivery, a transmitting or receiving application can confirm that a message has been written to disk before sending or requesting the data. The message store assured delivery feature also offers the ability to set a maximum time limit after which messages are automatically written to disk.
  • The combination of message store assured delivery along with ACK feedback notification to applications offers a high level of assured delivery along with high performance. This combination can be beneficial to financial markets front office applications such as order routing systems which require both extremely fast execution and assurance that messages not be lost.
  • Message store assured delivery includes three basic configuration parameters:
    • TimeToWrite: Normally messages are written to disk when the memory buffer is full. This setting allows the writing operation to be initiated by time as well as the filling of the buffer. This can increase the chance that the messages will be on nonvolatile storage if the message store server goes down.
    • AckAfterWrite: This setting tells the message store not to ACK back to the transmitter until after the data is written to nonvolatile storage. This allows a transmitter to know what has been written.
    • RouteAfterWrite: This setting tells a transmitter not to route a message to a receiver until after it is written to nonvolatile storage. This allows a receiver to only receive messages which have been written.
  • Message store assured delivery is supported on Linux and Windows® only.

Synchronous event delivery

Synchronous event delivery offers the ability to specify that when a defined condition is detected an event notification is immediately delivered. No additional messages are delivered on the associated topic until the event is processed by the application.

  • Previously in Low Latency Messaging, events notifications were delivered asynchronously, so when an event occurred, a notification was added to a queue and then delivered in sequence. However, for some applications, it is important that an event be delivered synchronously, so that when the event is detected, it is immediately delivered and no further action is taken until the event is fully processed by the application. The new synchronous event delivery now makes this possible.

    An example of when this can be useful is a case in which packet loss is viewed as a critical problem. In this situation, an application may not want to process any more messages after it is determined that a message is lost. This can free the application from having to continue to maintain and check sequence numbers to detect gaps in message delivery until the lost message is retransmitted and received.

Support for split brain prevention and detection

The new split brain prevention and detection capabilities are enhancements to the Reliable and Consistent Message Streaming (RCMS) high-reliability capabilities of Low Latency Messaging. These features can help address issues that can occur in multi-tiered environments that feature component replication. The split brain prevention capability is designed to address a situation in which more than one server acts as the primary server.

Split brain detection can be used to identify an incorrect situation in which tier members produce different outputs.

  • Split brain prevention: A split brain situation can occur, for example, if there are communications problems between servers on different tiers. A split brain situation can cause undesirable behavior due to a lack of synchronization between tiers. To address this condition, a new interface in RCMS called an arbitrator is added to prevent split brain situations.

    The role of the arbitrator is to stay aware of the primary server, to designate a new primary server if the old primary goes down, and to take a defined appropriate action if and when the original primary comes back up. The new feature includes a default arbitrator implementation, and also provides an API interface which enables application developers to create their own custom arbitrator.

  • Split brain detection: RCMS provides another feature called synchronization checkpoints, which can be used to identify an incorrect situation where the tier members produce different outputs. The application can check on a periodic basis using a message checksum that all tier members produce the same output. In case RCMS detects that the checksum comparison failed, an event notification is raised to the application.
  • Split brain prevention and detection are supported on Linux only.

RCMS message filtering and stream acceptance

  • RCMS Message filtering provides a mechanism that allows an application to use message properties and TurboFlow (labels or bitmaps) on RCMS topics in the same way they are used on other RMM topics. RCMS ensures that messages are filtered in a consistent manner by all the tier members. To do so, message filtering is performed by the underlying transport layer of the tier leader, and RCMS synchronizes the filtering between the tier members to be consistent with the filtering of the tier leader. This helps ensure that message filtering remains fast and efficient even in an RCMS environment.
  • The RCMS accept stream callback allows an RCMS topic receiver to be configured to accept streams without knowing the name of the topics in advance. RCMS still requires that all tier members receive exactly the same data on each tier topic and that all the streams that are accepted by a specified tier topic are identical.

Multi Host Channel Adapter (HCA) support for Native InfiniBand

This feature provides the ability for a single instance of Low Latency Messaging to use more than one HCA interface when using native InfiniBand.

Multi HCA support for Native Infiniband is supported on Linux only.

RUM latency monitoring

RUM latency monitoring extends the previously supported RMM latency monitoring to the reliable unicast transport. Latency monitoring provides information on the internal latency within RUM transmitters and receivers. It also provides statistics on the status of key queues, which may indicate accumulation of packets or messages leading to increased latency. An application can dynamically set latency monitoring parameters to balance between resources consumed by the monitoring process and the amount of information that is provided.

Additional platform support

  • Linux on IBM System p is now supported. The level of function is equivalent to the function available on Linux on x86.
  • Red Hat Enterprise MRG, which is the Red Hat Realtime Linux distribution, is now supported.

Documentation enhancements

Documentation enhancements include additions to the on-line Information Center problem determination section and a new section on performance tuning on Linux.

  • Enhancements to the Low Latency Messaging Information Center problem determination section includes additional documentation on Low Latency Messaging notification messages along with descriptions and user response for each.
  • The new performance tuning section in the Information Center offers application developers techniques and recommendations to help optimize Low Latency Messaging performance on Linux

Technology preview of support for clock synchronization technology

This feature is a non-supported technology preview that offers the ability to synchronize clocks accurately across machines. This clock synchronization technology feature provides a Coordinated Cluster Time (CCT) source, which is a high-resolution clock that is synchronized across machines. Low Latency Messaging can be configured to use the CCT as its time source which can be used to accurately monitor latency across multiple machines, and also to accurately synchronize timestamps with the Low Latency Message Store. This technology preview currently only runs on Linux on x86.

As a technology preview, this feature is under development, is potentially not reliable, and is not part of the supported generally available program.

IBM provides this technology preview without obligation of support and "as is," with no warranty of any kind, either express or implied, including the warranty of title, non-infringement or interference and the implied warranties and conditions of merchantability and fitness for a particular purpose. The entire risk arising out of the use or performance of the technical preview code remains with the user.

Performance considerations

WebSphere MQ Low Latency Messaging is a scalable product. Performance depends on the complexity of the specific environment, volume of data traffic, and the data object size. The stated performance numbers are based on measurements using standard IBM benchmarks in a controlled environment. The actual throughput that any application will experience may vary depending upon considerations such as message size, transmission rate, hardware platform, and network configuration. Therefore, no assurance can be given that an individual application will achieve the throughput or latency stated here. Customers should conduct their own testing. For more detailed performance information, consult your IBM sales representative.

Charge metrics definitions

Processor Value Unit (PVU)

Processor Value Unit (PVU) is a unit of measure by which this software product can be licensed. PVU entitlements are based on processor technology (defined within the PVU table4 by processor vendor, brand, type and model number). IBM continues to define a processor, for purposes of PVU-based licensing, to be each processor core on a chip. Each software product has a unique price per PVU. To determine the total cost of deploying an individual software product in a specific hardware environment, you must take the following steps:

  1. For each processor core in the hardware environment on which the software product is to be licensed, determine the PVU requirement based on its processor technology per the PVU table4.
  2. Add the PVU requirements for all processor cores in the hardware environment.
  3. Multiply the software product's price per PVU by the total number of PVUs required as determined in step 2 above.

PVU entitlements are specific to a software product and may not be exchanged, interchanged, or aggregated with PVU entitlements of another software product.

Unless you have deployed eligible sub-capacity products according to the sub-capacity4 terms, you must obtain PVU Proof of Entitlements (PoEs) for the maximum number of activated5 physical processor cores in the hardware environment made available to or managed by the software product.

Activated processor cores are physical processor cores that are available for use in a server. They include processor cores:
  • That are activated (available for use) when the server is shipped by the manufacturer
  • That are activated subsequently through activation codes purchased from the server manufacturer by the customer
  • Whose capacity can be limited by the customer through Virtualization technologies, Operating System commands and BIOS settings

Client Device

Client Device is the unit of measure by which this program is licensed. A Client Device is a computing device that requests the execution of a set of commands, procedures, or applications from another computer system that is typically referred to as a server. Multiple Client Devices may share access to a common server. A Client Device generally has some processing capability or is programmable to allow a user to do work. A Proof of Entitlement (PoE) must be obtained for each Client Device accessing the program in any manner on each and every single computer or server where the program is installed.

Examples include, but are not limited to appliances, automated teller machines, cash registers, desktop computers, kiosks, notebook computers, personal digital assistant, point-of-sale terminals, and technical workstations.
