Replicate Multiple LinkedIn Accounts via the CData Sync CLI

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

Configure LinkedIn Connections

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

Windows

<?xml version="1.0" encoding="UTF-8" ?>
<CDataSync>
  <DatabaseType>SQLite</DatabaseType>
  <DatabaseProvider>System.Data.SQLite</DatabaseProvider>
  <ConnectionString>OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:portNumber;CompanyId=XXXXXXX</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>OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:portNumber;CompanyId=XXXXXXX</ConnectionString>
  <ReplicateAll>False</ReplicateAll>
  <NotificationUserName></NotificationUserName>
  <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString>
</CDataSync>

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

REPLICATE CompanyStatusUpdates;

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 LinkedIn accounts into the same database:

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

REPLICATE PROD_CompanyStatusUpdates SELECT * FROM CompanyStatusUpdates 

Alternatively, you can use a different schema:

REPLICATE PROD.CompanyStatusUpdates SELECT * FROM CompanyStatusUpdates

Run Sync

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

Windows

LinkedInSync.exe -g MyProductionLinkedInConfig.xml -f MyProductionLinkedInSync.sql

Java

java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar LinkedInSync.jar -g MyProductionLinkedInConfig.xml -f MyProductionLinkedInSync.sql
