Replicate Sybase Data to Multiple Databases

Always-on applications rely on automatic failover capabilities and real-time access to data. CData Sync integrates live Sybase data into your mirrored databases, always-on cloud databases, and other databases such as your reporting server: Automatically synchronize with remote Sybase data from Windows.

Configure Replication Destinations

Using CData Sync, you can replicate Sybase data to any number of databases, both cloud-based and on-premises. To add a replication destination, navigate to the Connections tab.

For each destination database:

1. Click Add Connection.
2. Select a destination. In this article, we use SQLite.
3. Enter the necessary connection properties. To replicate Sybase to a SQLite database, enter a file path in the Data Source box.
4. Click Test Connection to ensure that the connection is configured properly.
5. Click Save Changes.

Configure the Sybase Connection

You can configure a connection to Sybase from the Connections tab. To add a connection to your Sybase account, navigate to the Connections tab.

1. Click Add Connection.
2. Select a source (Sybase).
3. Configure the connection properties.
   
   

   To connect to Sybase, specify the following connection properties:

   • Server: Set this to the name or network address of the Sybase database instance.
   • Database: Set this to the name of the Sybase database running on the specified Server.

   Optionally, you can also secure your connections with TLS/SSL by setting UseSSL to true.

   Sybase supports several methods for authentication including Password and Kerberos.

   Connect Using Password Authentication

   Set the AuthScheme to Password and set the following connection properties to use Sybase authentication.

   • User: Set this to the username of the authenticating Sybase user.
   • Password: Set this to the username of the authenticating Sybase user.

   Connect using LDAP Authentication

   To connect with LDAP authentication, you will need to configure Sybase server-side to use the LDAP authentication mechanism.

   After configuring Sybase for LDAP, you can connect using the same credentials as Password authentication.

   Connect Using Kerberos Authentication

   To leverage Kerberos authentication, begin by enabling it setting AuthScheme to Kerberos. See the Using Kerberos section in the Help documentation for more information on using Kerberos authentication.

   You can find an example connection string below: Server=MyServer;Port=MyPort;User=SampleUser;Password=SamplePassword;Database=MyDB;Kerberos=true;KerberosKDC=MyKDC;KerberosRealm=MYREALM.COM;KerberosSPN=server-name

4. Click Connect to ensure that the connection is configured properly.
5. Click Save Changes.

Configure Replication Queries

CData Sync enables you to control replication with a point-and-click interface and with SQL queries. For each replication you wish to configure, navigate to the Jobs tab and click Add Job. Select the Source and Destination for your replication.

Replicate Entire Tables

To replicate an entire table, click Add Tables in the Tables section, choose the table(s) you wish to replicate, and click Add Selected Tables.

Customize Your Replication

You can use a SQL query to customize your replication. 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 Sybase API. To customize your replication, click Add Custom Query in the Tables section and define the Query Statement.

The statement below caches and incrementally updates a table of Sybase data:

REPLICATE Products;

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 Sybase accounts into the same database:

• Use a different table prefix in the REPLICATE SELECT statement:

  REPLICATE PROD_Products SELECT * FROM Products;

• Alternatively, use a different schema:

  REPLICATE PROD.Products SELECT * FROM Products;

Schedule Your Replication

In the Schedule section, you can schedule a job to run automatically, configuring the job to run after specified intervals ranging from once every 10 minutes to once every month.

Once you have configured the replication job, click Save Changes. You can configure any number of jobs to manage the replication of your Sybase data to disparate on-premises, cloud-based, and other databases.
