Introduction

This chapter presents a tutorial to lead you through setting up a SQL Remote installation. The installation replicates data between an Adaptive Server Enterprise database (the consolidated database) and an Adaptive Server Anywhere database (the remote database).

Goals

In the tutorial you act as the system administrator of a consolidated Adaptive Server Enterprise database, and set up a simple replication system. The replication system consists of a simple sales database, with two tables.

The consolidated database holds all of the database, while the remote database has all of one table, but only some of the rows in the other table.

The tutorial takes you through the following steps:

Creating a consolidated database on your Adaptive Server Enterprise server.

Creating a file-sharing replication system with a single Adaptive Server Anywhere remote database.

Replicating data between the two databases.

The database

 

The tutorial uses a simple two-table database. One table holds information

 

about sales representatives, and the other about customers. The tables are

 

much simpler than you would use in a real database; this allows us to focus

 

just on those issues important for replication.

Database schema

The database schema for the tutorial is illustrated in the figure.

Customer

cust_key char(10)

name char(40)

rep_key char(5)

rep_key =

rep_key

SalesRep

rep_key char(5)

name char(40)

Features to note include the following:

Each sales representative is represented by one row in the SalesRep table.

Each customer is represented by one row in the customer table.

Each customer is assigned to a single Sales representative, and this assignment is built in to the database as a foreign key from the Customer
