Replicate Multiple Tanda Accounts via the CData Sync CLI

CData Sync for Tanda 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 Tanda connections. In this article we show how to use the CLI to replicate multiple Tanda accounts.

Configure Tanda Connections

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

Windows

<?xml version="1.0" encoding="UTF-8" ?>
<CDataSync>
  <DatabaseType>SQLite</DatabaseType>
  <DatabaseProvider>System.Data.SQLite</DatabaseProvider>
  <ConnectionString>Profile=C:\profiles\Tanda.apip;Authscheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;</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>Profile=C:\profiles\Tanda.apip;Authscheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;</ConnectionString>
  <ReplicateAll>False</ReplicateAll>
  <NotificationUserName></NotificationUserName>
  <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString>
</CDataSync>

Set the ProfileSettings connection property to the connection string for Tanda (see below).

Tanda API Profile Settings

Register an OAuth application at the Tanda applications page by clicking New App and entering your app name and redirect URI.

Configure Queries for Each Tanda 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 Tanda API. The statement below caches and incrementally updates a table of Tanda data:

REPLICATE ActiveShifts;

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 Tanda accounts into the same database:

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

REPLICATE PROD_ActiveShifts SELECT * FROM ActiveShifts 

Alternatively, you can use a different schema:

REPLICATE PROD.ActiveShifts SELECT * FROM ActiveShifts

Run Sync

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

Windows

APISync.exe -g MyProductionAPIConfig.xml -f MyProductionAPISync.sql

Java

java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar APISync.jar -g MyProductionAPIConfig.xml -f MyProductionAPISync.sql
