You can use a SQL Anywhere, Adaptive Server Enterprise, Oracle, Microsoft SQL Server, or IBM DB2 MobiLink consolidated database as your consolidated database. Your MobiLink consolidated database is a central repository of data and includes MobiLink system tables and stored procedures used to manage the synchronization process. With direct row handling, you synchronize with a data source other than a consolidated database, but you still need a consolidated database to maintain information used by the MobiLink server.
In this lesson, you will:
Create a database and define an ODBC data source.
Add data tables to synchronize to remote clients.
Install MobiLink system tables and stored procedures.
If you already have a MobiLink consolidated database set up with MobiLink system objects and a DSN, you can skip this lesson.
In this tutorial, you create a SQL Anywhere database using the Sybase Central Create a Database wizard.
Start Sybase Central.
Choose Start > Programs > SQL Anywhere 10 > Sybase Central.
Sybase Central appears.
In Sybase Central, choose Tools > SQL Anywhere 10 > Create Database.
The Create Database wizard appears.
Leave the default of Create Database on this Computer, and then click Next.
Enter the file name and path for the database. For example, enter:
Follow the remaining instructions in the wizard, accepting the default values, except as follows.
Uncheck the option to Install jConnect Meta-Information Support.
Uncheck the option to Stop the Database After Last Disconnect.
The database called MLconsolidated appears in Sybase Central.
Use the SQL Anywhere 10 driver to define an ODBC data source for the MLconsolidated database.
Start the ODBC Administrator:
From the Sybase Central Tools menu, choose SQL Anywhere 10 > Open ODBC Administrator.
The ODBC Data Source Administrator appears.
On the User DSN tab, click Add.
The Create New Data Source dialog appears.
Select SQL Anywhere 10, and then click Finish.
The ODBC Configuration for SQL Anywhere 10 dialog appears.
On the ODBC tab, type the Data source name mobilink_db. On the Login tab, type DBA for the User ID and sql for the Password. On the Database tab, type MLconsolidated for the Server Name and c:\MLdirect\MLconsolidated.db for the Database file.
Click OK to define the data source and OK again to close ODBC Administrator.
In this procedure, you create the RemoteOrders table in the MobiLink consolidated database. The RemoteOrders table contains the following columns:
A unique identifier for orders.
A unique identifier for products.
The number of items sold.
The order status.
The last modification date of a row. You use this column for timestamp based downloads, a common technique used to filter rows for efficient synchronization.
Connect to your database using Interactive SQL.
You can start Interactive SQL from Sybase Central or from a command prompt.
To start Interactive SQL from Sybase Central, click your database MLconsolidated - DBA. From the Sybase Central File menu, choose Open Interactive SQL.
To start Interactive SQL at a command prompt, type the following command:
dbisql -c "dsn=mobilink_db"
Run the following command in Interactive SQL to create the RemoteOrders table.
CREATE TABLE RemoteOrders ( order_id integer not null, product_id integer not null, quantity integer, order_status varchar(10) default 'new', last_modified timestamp default current timestamp, primary key(order_id) )
Interactive SQL creates the RemoteOrders table in your consolidated database.
Stay connected in Interactive SQL for the following procedure.
You can find setup scripts for each supported consolidated database (SQL Anywhere, Adaptive Server Enterprise, Oracle, Microsoft SQL Server, and IBM DB2) in the MobiLink/setup subdirectory of your SQL Anywhere 10 installation.
In this procedure you set up a SQL Anywhere consolidated database. You do this using the syncsa.sql setup script. Running syncsa.sql creates a series of system tables and stored procedures prefaced with ml_. The MobiLink server works with these tables and stored procedures in the synchronization process.
Connect to your consolidated database in Interactive SQL if you are not already connected.
At a command prompt, type the following command:
dbisql -c "dsn=mobilink_db"
Run the following command in Interactive SQL to create MobiLink system tables and stored procedures. Replace c:\Program Files\SQL Anywhere 10\ with the location of your SQL Anywhere 10 installation.
read "c:\Program Files\SQL Anywhere 10\MobiLink\setup\syncsa.sql"
Interactive SQL applies syncsa.sql to your consolidated database.
Stay connected in Interactive SQL for the next lesson.
