Release Notes
UM Version 6.5

The most-significant update to UM version 6.5 is the introduction of the Ultra Messaging System Monitoring option.

Warning
UM version 6.5 does not interoperate reliably with versions of UM prior to 6.0 It was not until UM version 6.7 and beyond that interoperability was introduced between the 6.x version line and the 5.x version line.


Enhancements for 6.5  <-


Streaming Enhancements for 6.5  <-

The following new features and enhancements apply to UMS, UMP, and UMQ products.

Change Request

Description

7911

You can now configure Ultra Messaging to use Solarflare Onload to select transport sockets for acceleration. Onload is a kernel-bypass technology that accelerates message traffic and operates with Solarflare 10GbE Ethernet NICs. See Solarflare® Onload for more information.

7974 The lbmrd daemon now includes command line option '-f' or '--lic-file' to let you specify the Ultra Messaging license file.


Persistence Enhancements for 6.5  <-

The following new features and enhancements apply to UMP and UMQ products.

Change Request

Description

7478 The Persistent Store Web Monitor now displays the Session ID on the Store page, Source page, and Receiver page.


Queuing Enhancements for 6.5  <-

Note
The brokered queuing and UM JMS functionalities were replaced in version 6.8, so most of these notes do not apply to more-recent versions of UM. However, ULB functionalty is retained.

The following new features and enhancements apply to the UMQ product.

  • None.


Dynamic Router Enhancements for 6.5  <-

The following new features and enhancements apply to the Dynamic Routing Option (DRO).

Change Request

Description

7694 You can now use the LBT-SMX transport to send ingress message traffic to a UM Router (DRO). The UM Router no longer ignores topic resolution traffic from a LBT-SMX source. You still cannot, however, use LBT-SMX to send egress traffic from a UM Router.


Ultra Messaging System Monitoring Option  <-

In conjunction with the Ultra Messaging 6.5 release, Informatica has introduced the Ultra Messaging System Monitor Option (UMSM). Administrators can use UMSM to monitor components of an Ultra Messaging deployment. The UMSM dashboard displays the status of components, such as UM hosts, transports, topic resolution domains, and application instances, as well as UM statistics.

UMSM monitors the messaging traffic of Ultra Messaging versions 5.0 and later.

With the Ultra Messaging 6.5 release, Ultra Messaging Automatic Monitoring sends the following aggregated receiver statistics and subscription information to UMSM:

  • Aggregate number of topic-level sequence numbers received out of order.
  • Aggregate number of topic-level sequence numbers declared unrecoverably lost by the delivery of either an LBM_MSG_UNRECOVERABLE_LOSS or LBM_MSG_UNRECOVERABLE_LOSS_BURST event to the receiving application.
  • Receiver callback service time statistics. Ultra Messaging tracks the mean time, maximum time, and minimum time to service receiver callbacks.

As the collection of aggregated statistics can increase the latency of message delivery, Ultra Messaging does not collect them by default. You can enable UMSM to collect the aggregated message loss statistics with the UM configuration options, monitor_interval (receiver) and monitor_interval (wildcard_receiver). You can access the aggregated receiver statistics with UMSM. The lbmmon API does not provide access to the aggregated receiver statistics.

The Ultra Messaging 6.5 release contains a third new UM configuration option, receiver_callback_service_time_enabled (context), which enables UMSM to maintain receiver callback service times. The lbmmon API does not provide access to the receiver callback service times.
