HP Pathway with NonStop TS/MP version 2.4 software: Pathway for the 21st century |
|
|
The latest release of Pathway with NonStop TS/MP software, version 2.4, is available now and includes significant new features:
Online application upgrade with Pathway domains Pathway with NonStop TS/MP version 2.3 software introduced the Pathway domains feature, which improves application availability by eliminating planned outages, and increases Pathway configuration limits. Pathway domains enable you to configure multiple, identical Pathway environments (PATHMONs) that can behave as a single, large Pathway application. Any of the environments within a domain may be taken down in turn for reconfiguration, while the remaining environments within the domain continue processing work with no interruption. This enables online rebalancing of Pathway environments and prevents loss of service typically encountered whenever an update must be made to a running Pathway system. By replicating an application environment across a Pathway domain, the configuration limits of a single Pathway environment are removed. The maximum number of environments which may be included within a Pathway domain is four, so the configuration limits of a single Pathway environment may be increased by up to four times by using the Pathway domain feature.
The PDMI interface is also improved to allow single “domain-level” commands which are applied across all of the Pathway environments in the domain (as opposed to having to operate on each Pathway environment independently). Large Pathsend message support With the increasing usage of large message structures such as XML documents, the 32KB maximum single Pathsend message size limit has become a significant restriction. HP is very pleased to announce that with Pathway with NonStop TS/MP version 2.4 software, this single Pathsend message size limit has been raised to 2MB. This is achieved by support for new APIs which must be used by both requesters and servers wishing to use large Pathsend messages. Very important note – upward compatibility is maintained, and existing applications which do not wish to take advantage of this new feature do not need to change to work with version 2.4, the current APIs will continue to operate as normal. In addition, NonStop SOAP and JToolkit for NonStop Servers, are being enhanced to take advantage of this new large Pathsend message support. These enhancements enable applications using these other products to exploit the large Pathsend message capability, and will greatly facilitate for example the deployment of SOA, web services, and Java applications on HP NonStop servers. Performance and capacity increases In order to fully exploit the increased capacity of the HP Integrity NonStop server, an ongoing process of raising and removing Pathway limits has been underway. The following limits were increased by Pathway with NonStop TS/MP version 2.3 software:
Other important enhancements Pathway with NonStop TS/MP version 2.4 software also includes other significant enhancements:
The enhancements provided with the latest version of Pathway with NonStop TS/MP software allow Pathway applications to take full advantage of the power and capacity of HP Integrity NonStop and HP Integrity NonStop BladeSystem servers. This combination of new software and hardware provides a continued growth path for Pathway users, as well as unparalleled performance and availability for the most demanding business-critical OLTP applications.
