Replicate SAS Data Sets Data to Multiple Databases


Replicate SAS Data Sets data to disparate databases with a single configuration.

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

Connect to SAS Data Sets 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>URI=C:/myfolder;</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>URI=C:/myfolder;</ConnectionString> <ReplicateAll>False</ReplicateAll> <NotificationUserName></NotificationUserName> <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString> </CDataSync>

Set the following connection properties to connect to your SAS DataSet files:

Connecting to Local Files

  • Set the Connection Type to "Local." Local files support SELECT, INSERT, and DELETE commands.
  • Set the URI to a folder containing SAS files, e.g. C:\PATH\TO\FOLDER\.

Connecting to Cloud-Hosted SAS DataSet Files

While the driver is capable of pulling data from SAS DataSet files hosted on a variety of cloud data stores, INSERT, UPDATE, and DELETE are not supported outside of local files in this driver.

Set the Connection Type to the service hosting your SAS DataSet files. A unique prefix at the beginning of the URI connection property is used to identify the cloud data store and the remainder of the path is a relative path to the desired folder (one table per file) or single file (a single table). For more information, refer to the Getting Started section of the Help documentation.

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 SAS Data Sets API. The statement below caches and incrementally updates a table of SAS Data Sets data:

REPLICATE restaurants;

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

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

Java

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