Anyway, here is an example, if you click the hyperlink at
the top of the page, it will take a while (compared to
old Mosaic, or other browsers) to jump to the right place.

By the way, it seems like if you have a image background
and while you are scrolling the page or pageup/pagedown, 
the display screen blinks a lot.

Data

Synchronization

Overview

 

Concepts

Some data synchronization concepts are summarized here to provide a basic understanding of the data synchronization capability:

Specifications

The data synchronization tool is configured with a specification file and command to activate the specifications, as follows:

ds_specs data_sync.421

The specification file is divided into different sections. The types of sections contained in the file are:

  • header
  • collector
  • output
  • collector group

Table 1 - Information Contained in the Header

Information Description
Collection Start Event: This event should be set by the user or gp-test to request the start of a synchronized data collection. Required.
Collection Stop Event: The name of an event which will be set by the user to request the synchronized data collection in progress be stopped and the data collected up to the stop point be stored. Required.
Collection Abort Event: The name of an event which will be set by the user to request the synchronized data collection in progress be aborted and all data gathered and not yet stored be discarded. Required.
Data Synchronization Variable The label of an integer variable which will be incremented at the start of a new synchronized collection. The variable has to exist already in the ASSET system and will typically be a general usage variable. The variable is used as part of the key for storing data. The variable should be identified as a saved parameter if there is an interest in maintaining a unique key over a long period of time. Optional.

An example of a header section is:

#AbortOnErr

Table 2 - Information in the Collector Section

 

An example of a collector section is:

$Collector

Output Header:

The information contained in an output section header is:

Table 3 - Information in the Output Section Header

Table 5 - Information in a PAM Flat File Specification Section

Information Description
PAM Spec File Name: The path of a file which contains the specifications for a PAM data point. See the User Manual section on PAM for more information about this specification file format.
