ATTENTION

This directory must be created manually on Subscriber systems. Also a copy of

the Messenger_CFG.mdb with the exact layout of the database of the publisher

must be created in this directory. If the database is missing or has incorrect

layout, system malfunction results. An update of eKERNEL on the Publisher site

must always be synchronized with the same update on subscribers systems,

and the eKERNEL can automatically add changes to the database at startup.

Therefore, after applying a new version of eKERNEL, you must first start

eKERNEL, and then copy the Messenger_CFG.mdb database.

If you install new versions of eKERNEL, you must synchronize

the eKERNEL modules on all systems. Also the latest layout of

Messenger_CFG of publisher (after automatic upgrade changes at first

run) must be manually placed in the directory of the Subscribers.

GetImage puts a file Messenger_CFG.xml in the same directory, and

replaces this file on receipt of a GetImage result.

If you want to review this file, make a copy in another location before

doing so, for example, C:\Temp. You can, for example, launch the Internet

Explorer and associate XML files to this program, as Internet Explorer has

built-in functionality to parse XML documents.

WARNING

Do not open the file in the C:\SOPHO Messenger@Net\Xml,

because the file can be allocated by the viewer, and must be

replaced when the next KeepAlive result is received.

SQL script

When a Subscriber detects a change between P:1 and P:0:

1. The Subscriber ends all running tasks associated with the current

environment.

At this time, Messenger functionality is disrupted, and pending and new

alarms can be lost.

2. The SQL image in C:\SOPHO Messenger@Net\Xml repository

Messenger_CFG.xml is imported to the workspace C:\SOPHO

Messenger@Net\Xml access database Messenger_CFG.mdb. For this

reason, the Messenger_CFG.mdb on Publisher and Subscriber sites

must always use the same layout.

Thus the following repositories exist:

• (original database on publisher)

C:\SOPHO Messenger@Net\Mdb\Messenger_CFG.mdbat publisher

• (transferred as XML images through HTTP)
