The server (which is hosted at SAS Institute Inc.)remotely processes any submitted SAS files or projects and returns results to yourcomputer.If you are unable to use a SAS OnDemand for Academics software application toperform processing, then make sure that you have a working Internet connection.If your Internet connection is working normally, then you can check the SAS serverstatus web page at https://www.ondemand.sas.com/status/oda/ to determine whetherappropriate servers are available or temporarily down for maintenance.Avoid Connection Time-outsAvoid leaving open connections on the server. An open connection to the SAS server willlikely disconnect (time out) after one hour (or less) if the connection is idle (that is, youhave not performed any processing).

Many firewalls disconnect open sessions after anhour of idle time (or less). It is best practice to complete your work, save it, and then exitSAS OnDemand for Academics: Enterprise Guide before you leave the computer.SAS Server Maintenance and AvailabilitySAS makes its best efforts to make the server available as much as possible and to keepunexpected downtime to a minimum. There could be limited times when the server isunavailable because SAS is performing maintenance, testing, or performanceenhancement tasks.If server maintenance is needed, then SAS will try to perform this work duringnontraditional usage hours to lessen any impact to users.SAS uses the third Saturday of each month to perform scheduled maintenance onits systems (if needed). Therefore, the server might be unavailable for a portion oftime on the third Saturday of each month.SAS OnDemand for Academics: Enterprise GuideStep 4.

Review the Basics for Working with Data and ResultsBefore attempting course exercises, we recommend that you review the basics ofworking with SAS data sets and results in SAS OnDemand for Academics: EnterpriseGuide.Working with DataTo ensure that you do not lose your work, you should cover the basics of uploading anddownloading files from the SAS server.Storing DataThere are two ways to store data for use with SAS OnDemand for Academics:Instructors can choose to store data for course exercises on the SAS server. Youcan access the data using a LIBNAME or FILENAME statement that yourinstructor provides you.Instructors or students can store the data that they want to use on a data sourcethat can connect to their PC.

Sources could include a local file system, universityspace (such as AFS or NFS space), or portable disk drives.Uploading Data Files to the SAS ServerIf the data that you want to use is not already available from the SAS server, then youcan use the Upload Data Files to Server task available within SAS OnDemand forAcademics: Enterprise Guide.The Upload Data Files to Server task enables you to select one or more SAS data sets(*.sas7bdat) from your local Microsoft Windows file system and copy them to the SASserver (the SAS Cloud) for processing.

You must perform this step in order to work withany local SAS data sets because the SAS server cannot access any data on your localdrives.10 Step 4. Review the Basics for Working with Data and ResultsChapter 2The task generates a log that summarizes the data files that were copied, the byte size,timings for each file and for all of the files as a group, and any errors that occurredduring the transfer. By default, all data files are added as output data in your SASEnterprise Guide project so that they can be used in the project.Note: Because any modifications that you make to the data will not be saved once youend your session, you might want to download any data files that you have changedfrom the SAS server to your local PC after you have finished your work.To upload a data set:Select the SAS data sets to upload.Specify the upload options.To select the SAS data sets to upload:Select Tasks  Data  Upload Data Files to Server.
