TS/MP Release Supplement

Introduction to TS/MP 2.3

HP NonStop TS/MP Release Supplement—546055-006

2-3

Applications

If you are not using any new feature from the TS/MP 2.3 product, you do not need to

modify your existing application. However, as TS/MP 2.3 has new link management

algorithms, you may want to make some configuration modifications in the existing

application for performance tuning purposes. For information on how to modify the

configuration of your existing application, see Link Management

In most cases, no changes are required to the applications if using the new Pathway

domain feature.

The TS/MP 2.3 Pathsend library replaces the TS/MP 2.0 Pathsend library. Although,

both Pathsend libraries function similarly, they are internally different and cannot be

used interchangeably. Therefore, you might need to migrate the application to TS/MP

2.3. For information on migrating applications, see Section 5, Migrating Applications to

TS/MP 2.3 and Later Versions.

Management and Control

Pathway Domain Management Interface (PDMI) is a new management interface

introduced in TS/MP 2.3. The PDMI can be used when you want to configure multiple

PATHMON processes with replicated configurations, while using the Pathway domain

feature.

Event and Error Messages

The ACS subsystem returns a new set of EMS messages that functionally replace the

messages formerly returned by the LINKMON process. Similarly, the ACS subsystem

Pathsend APIs return a new set of errors. Messages returned by the TS/MP

PATHMON process are unchanged.

For information on EMS messages, see the

Operator Messages Manual.

For information on the ACS subsystem EMS event tokens, see Section 14, ACS

Subsystem Messages in the

TS/MP Management Programming Manual.

For information on the ACS SCF errors, see Section 9, SCF Error Messages

For information on ACS API errors, see Section 7, Pathsend Errors for ACS

Subsystem in the

TS/MP Pathsend and Server Programming Manual.

New Pathsend Limits

TS/MP 2.3 contains a link-management architecture designed for the more powerful

processors typically installed in the current NonStop systems. It provides higher

Note. Before running TS/MP Pathsend applications, you must start the ACS subsystem. HP

recommends that you start PATHMON processes after the ACS subsystem is started. For

information on configuring and starting the ACS subsystem, see Section 6, Installing and

Configuring and Section 7, Managing the ACS Subsystem.
