2 Introduction to TS/MP 2.5
TS/MP 2.5 is a newer version of TS/MP software, which is used as a replacement for TS/MP 2.0
and later versions.
This section includes these topics:
• “Overview of TS/MP” (page 28)
• “TS/MP Features” (page 29)
• “TS/MP Earlier Version Features” (page 32)
• “Compatibility with TS/MP 2.0” (page 36)
Overview of TS/MP
Pathway, along with NonStop TS/MP software, provides application server functionality that allows
you to develop and deploy mission-critical online transaction processing (OLTP) applications on
Integrity NonStop servers. This software helps you to concentrate on implementing business logic,
without being concerned with common application services such as load balancing, communications,
I/O, and fault tolerance. These common services are provided by TS/MP application server
software, comprising a run time execution environment and a set of APIs. In this way, TS/MP
software supplies a high-performance and a highly available OLTP application environment.
The TS/MP software consists of the PATHMON process, the ACS subsystem process, the PATHCOM
process and interface, and the Pathsend procedure calls. Upon integration with the NonStop
Transaction Management Facility (TMF) product, the TS/MP software forms the foundation for the
open transaction processing and client/server products on NonStop systems. Such products include
the NonStop Tuxedo system, the RSC/MP product, and NonStop JSP. The Pathway/iTS product
supports requestor programs that run in the Guardian environment, and to communicate with
terminals and intelligent devices that require the services of the TS/MP product.
TS/MP 2.5 is intended for Pathway/iTS 1.1 or Pathsend users running TS/MP 2.0 and later
versions. TS/MP 2.5 cannot be used by Tuxedo (TS/MP 3.0) users. For Pathway/iTS 1.1 or
Pathsend users, TS/MP 2.5 provides the following features:
• Higher Pathsend limits per CPU over TS/MP 2.0 LINKMON
• Higher PATHMON/Pathcom configuration (MAXASSIGNS/MAXDEFINES) limits
• Higher Pathway configuration and environment limits over TS/MP 2.0
• Wildcard support through Pathcom interface
• Default security attribute of PATHMONs changed from ‘N’ to ‘O’
• New management interface called PDMI to configure and manage multiple Pathway
applications under a single domain
• Higher Pathway environments per CPU over TS/MP 2.0
• Higher number of concurrent Pathsends per CPU over TS/MP 2.0
• Higher number of requestors per CPU over TS/MP 2.0
• Efficient link management
• Higher server links per CPU over TS/MP 2.0
• Support for online Pathway re-configuration without disrupting application availability
