Replicate xBase Data to Multiple Databases
Replicate xBase data to disparate databases with a single configuration.
Always-on applications rely on automatic failover capabilities and real-time access to data. CData Sync for xBase integrates live xBase data into your mirrored databases, always-on cloud databases, and other databases such as your reporting server: Automatically synchronize with remote xBase data from Windows or any machine running Java.
You can use Sync's command-line interface (CLI) to easily control almost all aspects of the replication. You can use the CLI to replicate xBase data to one or many databases without any need to change your configuration.
Connect to xBase Data
You can save connection strings and other settings like email notifications in XML configuration files.
The following example shows how to replicate to SQLite.
Windows
<?xml version="1.0" encoding="UTF-8" ?>
<CDataSync><DatabaseType>SQLite</DatabaseType>
<DatabaseProvider>System.Data.SQLite</DatabaseProvider>
<ConnectionString>DataSource=MyDBFFilesFolder;</ConnectionString>
<ReplicateAll>False</ReplicateAll>
<NotificationUserName></NotificationUserName>
<DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString>
<TaskSchedulerStartTime>09:51</TaskSchedulerStartTime>
<TaskSchedulerInterval>Never</TaskSchedulerInterval>
</CDataSync>
Java
<?xml version="1.0" encoding="UTF-8" ?>
<CDataSync><DatabaseType>SQLite</DatabaseType><DatabaseProvider>org.sqlite.JDBC</DatabaseProvider>
<ConnectionString>DataSource=MyDBFFilesFolder;</ConnectionString>
<ReplicateAll>False</ReplicateAll>
<NotificationUserName></NotificationUserName>
<DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString>
</CDataSync>
The DataSource property must be set to the name of the folder that contains the .dbf files. Specify the IncludeFiles property to work with xBase table files having extensions that differ from .dbf. Specify multiple extensions in a comma-separated list.
Configure Replication Queries
Sync enables you to control replication with standard SQL. The REPLICATE statement is a high-level command that caches and maintains a table in your database. You can define any SELECT query supported by the xBase API. The statement below caches and incrementally updates a table of xBase data:
REPLICATE Invoices;
You can specify a file containing the replication queries. This enables you to use the same replication queries to replicate to several databases.
Run Sync
After you have configured the connection strings and replication queries, you can run Sync with the following command-line options:
Windows
xBaseSync.exe -g MySQLiteConfig.xml -f xBaseSync.sql
Java
java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar xBaseSync.jar -g MySQLiteConfig.xml -f xBaseSync.sql
