Replicate Multiple CData Connect AI Accounts via the CData Sync CLI

CData Sync for CData Connect AI is a stand-alone application that provides solutions for a variety of replication scenarios such as replicating sandbox and production instances into your database. Both Sync for Windows and Sync for Java include a command-line interface (CLI) that makes it easy to manage multiple CData Connect AI connections. In this article we show how to use the CLI to replicate multiple CData Connect AI accounts.

Configure CData Connect AI Connections

You can save connection and email notification settings in an XML configuration file. To replicate multiple CData Connect AI accounts, use multiple configuration files. Below is an example configuration to replicate CData Connect AI to SQLite:

Windows

<?xml version="1.0" encoding="UTF-8" ?>
<CDataSync>
 <DatabaseType>SQLite</DatabaseType>
 <DatabaseProvider>System.Data.SQLite</DatabaseProvider>
 <ConnectionString>AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;</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>AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;</ConnectionString>
 <ReplicateAll>False</ReplicateAll>
 <NotificationUserName></NotificationUserName>
 <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString>
</CDataSync>

There are two ways to connect to Connect AI: OAuth authentication and Basic authentication.

To connect to Connect AI using OAuth, set Auth Scheme to "OAuth." When the OAuth login page appears in your default web browser, log in to Connect AI to proceed.

If you are unable to use browser-based OAuth authentication to connect to Connect AI, you can use Basic authentication. In this case, set Auth Scheme to "Basic,"" and then set the User and Personal Access Token for Connect AI.

Connect to a Workspace

To connect the JDBC client to a specific workspace, you specify the workspace name in the Advanced tab of the JDBC driver for Connect AI.

Configure Queries for Each CData Connect AI Instance

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 CData Connect AI API. The statement below caches and incrementally updates a table of CData Connect AI data:

REPLICATE Account;

You can specify a file containing the replication queries you want to use to update a particular database. Separate replication statements with semicolons. The following options are useful if you are replicating multiple CData Connect AI accounts into the same database:

You can use a different table prefix in the REPLICATE SELECT statement:

REPLICATE PROD_Account SELECT * FROM Account 

Alternatively, you can use a different schema:

REPLICATE PROD.Account SELECT * FROM Account

Run Sync

After you have configured the connection strings and replication queries, you can run Sync with the following command-line options:

Windows

ConnectSync.exe -g MyProductionConnectConfig.xml -f MyProductionConnectSync.sql

Java

java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar ConnectSync.jar -g MyProductionConnectConfig.xml -f MyProductionConnectSync.sql
