Replicate EnterpriseDB Data to Multiple Databases via the CData Sync CLI

Always-on applications rely on automatic failover capabilities and real-time access to data. CData Sync for EnterpriseDB integrates live EnterpriseDB data into your mirrored databases, always-on cloud databases, and other databases such as your reporting server: Automatically synchronize with remote EnterpriseDB 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 EnterpriseDB data to one or many databases without any need to change your configuration.

Connect to EnterpriseDB 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>User=postgres;Password=admin;Database=postgres;Server=127.0.0.1;Port=5444</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>User=postgres;Password=admin;Database=postgres;Server=127.0.0.1;Port=5444</ConnectionString>
<ReplicateAll>False</ReplicateAll>
<NotificationUserName></NotificationUserName>
<DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString>
</CDataSync>

The following connection properties are required in order to connect to data.

• Server: The host name or IP of the server hosting the EnterpriseDB database.
• Port: The port of the server hosting the EnterpriseDB database.

You can also optionally set the following:

• Database: The default database to connect to when connecting to the EnterpriseDB Server. If this is not set, the user's default database will be used.

Connect Using Standard Authentication

To authenticate using standard authentication, set the following:

• User: The user which will be used to authenticate with the EnterpriseDB server.
• Password: The password which will be used to authenticate with the EnterpriseDB server.

Connect Using SSL Authentication

You can leverage SSL authentication to connect to EnterpriseDB data via a secure session. Configure the following connection properties to connect to data:

• SSLClientCert: Set this to the name of the certificate store for the client certificate. Used in the case of 2-way SSL, where truststore and keystore are kept on both the client and server machines.
• SSLClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
• SSLClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
• SSLClientCertType: The certificate type of the client store.
• SSLServerCert: The certificate to be accepted from the server.

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 EnterpriseDB API. The statement below caches and incrementally updates a table of EnterpriseDB data:

REPLICATE Orders;

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

EnterpriseDBSync.exe -g MySQLiteConfig.xml -f EnterpriseDBSync.sql

Java

java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar EnterpriseDBSync.jar -g MySQLiteConfig.xml -f EnterpriseDBSync.sql
