Replicate Multiple SAS xpt Accounts


Replicate multiple SAS xpt accounts to one or many databases.

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

Configure SAS xpt Connections

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

Windows

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

Connecting to Local SASXpt Files

You can connect to local SASXpt file by setting the URI to a folder containing SASXpt files.

Connecting to S3 data source

You can connect to Amazon S3 source to read SASXpt files. Set the following properties to connect:

  • URI: Set this to the folder within your bucket that you would like to connect to.
  • AWSAccessKey: Set this to your AWS account access key.
  • AWSSecretKey: Set this to your AWS account secret key.
  • TemporaryLocalFolder: Set this to the path, or URI, to the folder that is used to temporarily download SASXpt file(s).

Connecting to Azure Data Lake Storage Gen2

You can connect to ADLS Gen2 to read SASXpt files. Set the following properties to connect:

  • URI: Set this to the name of the file system and the name of the folder which contacts your SASXpt files.
  • AzureAccount: Set this to the name of the Azure Data Lake storage account.
  • AzureAccessKey: Set this to our Azure DataLakeStore Gen 2 storage account access key.
  • TemporaryLocalFolder: Set this to the path, or URI, to the folder that is used to temporarily download SASXpt file(s).

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

REPLICATE SampleTable_1;

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 SAS xpt accounts into the same database:

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

REPLICATE PROD_SampleTable_1 SELECT * FROM SampleTable_1

Alternatively, you can use a different schema:

REPLICATE PROD.SampleTable_1 SELECT * FROM SampleTable_1

Run Sync

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

Windows

SASXptSync.exe -g MyProductionSASXptConfig.xml -f MyProductionSASXptSync.sql

Java

java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar SASXptSync.jar -g MyProductionSASXptConfig.xml -f MyProductionSASXptSync.sql
