The LabKey/SAS client library is a set of SAS macros that retrieve data from an instance of LabKey Server as SAS data sets. The SAS macros use the Java Client Library to send, receive, and process requests to the server. This topic helps you set up SAS to work with LabKey.
Configure your SAS Installation to Use the SAS/LabKey Interface
The steps in this section illustrate the process; be sure to substitute your own current version numbers for the examples given.
- Install SAS
- Get the latest SAS client distribution, as follows:
- Go to the topic API Resources, which displays a table of API resources.
- In the row of SAS related links, click Distribution, which takes you to the Artifactory publication site.
- On Artifactory, select the .zip file, for example labkey-api-sas-1.0.0.zip, and click Download.
- Extract this file to a local directory (these instructions assume "c:\sas"). The directory should contain a number of .jar files (the Java client library and its dependencies) and 12 .sas files (the SAS macros).
- Open your default SAS configuration file, sasv9.cfg. You will find it in your SAS installation in a location similar to C:\Program Files\SASHome\x86\SASFoundation\9.3\nls\en)
- In the -SET SASAUTOS section, add the path to the SAS macros to the end of the list (e.g., "C:\sas")
- Configure your Java Runtime Environment (JRE) based on your SAS version. For current information, check the SAS documentation. You may need to install security updates or make other adjustments as recommended there.
- Near the top of sasv9.cfg, add a line like the following, including a path list surrounded by double quotes. The path list must use the correct separator for your operating system. For Windows, use a semicolon ";" and for Mac, us a colon ":"
-set classpath "[full paths to all .jar files]"
Example Java classpath for Windows (use the actual version numbers from the package you unpacked):
-set classpath "C:\sas\commons-codec-1.6.jar;C:\sas\commons-logging-1.1.3.jar;C:\sas\fluent-hc-4.3.5.jar;C:\sas\httpclient-4.3.5.jar;C:\sas\httpclient-cache-4.3.5.jar;C:\sas\httpcore-4.3.2.jar;C:\sas\httpmime-4.3.5.jar;C:\sas\json_simple-1.1.jar;C:\sas\opencsv-2.0.jar;C:\sas\labkey-client-api-15.2.jar"
Example Java classpath for Mac (use the actual version numbers from the package you unpacked):
-set classpath "/sas/commons-codec-1.6.jar:/sas/commons-logging-1.1.3.jar:/sas/fluent-hc-4.3.5.jar:/sas/httpclient-4.3.5.jar:/sas/httpclient-cache-4.3.5.jar:/sas/httpcore-4.3.2.jar:/sas/httpmime-4.3.5.jar:/sas/json_simple-1.1.jar:/sas/opencsv-2.0.jar:/sas/labkey-client-api-15.2.jar"
Configure LabKey Server and Run the Test Script
- On your local version of LabKey Server, create a list called "People" in your home folder, inferring the structure and populating it using the file "demo.xls".
- Configure your .netrc or _netrc file in your home directory.
- Run SAS
- Execute "proc javainfo; run;" in a program editor; this command should display detailed information about the java environment in the log. Verify that java.version matches the JRE you set above.
- Load demo.sas
- Run it
