General Questions

Data Questions

    Per the license agreement, you are solely responsible for the data or Content uploaded or accessed and for ensuring such data or Content is stored appropriately on your computer. SAS is not responsible for the accuracy of the data or Content, your use of the data or Content, or for any loss of data or Content. For the same reason, it is always a best practice to maintain downloaded backup copies of any important files that you intend to store on the ODA servers. The copies on the ODA servers should only be treated as temporary working copies.

  • Are there data storage limits (quotas)?
    Yes. All users have 5 GB of personal data storage. This data storage includes any SAS programs and projects that you create with software such as SAS Studio as well as any personal data that you upload. Additionally, instructors have the ability to upload up to 3 GB of course data in a separate course location. Instructors can then let the students who enroll in their course(s) access this course-specific data.

  • How do I check my data storage quota?
    Sign in through welcome.oda.sas.com to view the meter(s) of your personal quota usage (located on the right side of the Control Center). The quota usage value(s) include any SAS programs or projects that you have created as well as any personal data that you have uploaded.

    Alternatively, if you want a precise value instead of a percentage, then you can install and run a tool:


    Quota Usage Tool Installation
    1. Start SAS Studio software.
    2. From the left hand side, expand Server Files and Folders and then right-click on Folder Shortcuts.
    3. Select NewFolder Shortcut.
    4. In the Name field, enter Support.
    5. In the Directory field, enter /courses/support and then click Save.

    Quota Usage Tool Usage
    1. From the left hand side of SAS Studio, expand Server Files and Folders and then expand Folder Shortcuts.
    2. Expand the Support folder.
    3. Locate the file called Disk Usage Report.ctm.
    4. Right-click on the file and then select Open.
    5. When prompted, select Run (instead of Edit or Cancel) to run the program.
    6. Review the options on the left side of the program and make any changes that you want.
    7. Run the program (press the F3 key or click the Running Man icon).
    8. Click the Results tab to review your usage results.

  • What happens if I exceed my data storage quota?
    If you exceed your data storage quota (that is, you have in excess of 5 GB of projects, SAS files, or data files), then you will receive the following error when trying to run code in your software:

    User <username> has insufficient permissions to create /home/<username>/.. Contact your system administrator to resolve.

    or

    ERROR: An I/O error has occurred on file.

    You will also see a message indicating you are over your quota when you access your dashboard in SAS OnDemand for Academics.

    To correct this issue, you must delete personal SAS files or data files that you no longer need:

    1. Sign in through welcome.oda.sas.com.
    2. Click SAS Studio to start the program.
    3. From the left-hand side navigation pane, expand Server Files and Folders and then expand Files (Home).
    4. Review the various files and/or folders and delete files or projects that you no longer need. This will reduce the amount of quota space that you are using.

    Sign in through welcome.oda.sas.com to view the meter(s) of your personal quota usage. You might need to delete more files in order to create enough space to run SAS programs, create new projects or files, or upload additional data.

  • What is "Remove largest file in home directory" in the Quotas section?

    If you exceed your data storage quota, this self-service option will appear in your dashboard under the Quotas section. In some cases, being over quota can prevent SAS Studio from launching, thus limiting the ability to remove content from your home directory. This utility will assist by removing the largest file in your home directory regardless of file type. Since this is a forced removal and the largest file will not be recoverable, it is recommended to first attempt to remove files manually using SAS Studio.
    After running the utility a message will show you the location, file name, and size of the file that was removed.

  • Can I store files on the SAS Server?
    Instructors have the ability to upload and store up to 3 GB of course-specific data files on the SAS Server. The course data can then be accessed using an appropriate LIBNAME or FILENAME statement by students who have registered for that course. Instructors are provided with a unique LIBNAME and FILENAME statement for each course that they create.

    All users have up to 5 GB of storage for personal data files that they upload as well as for SAS programs created with SAS Studio. If you are a part of a course that uses SAS Enterprise Miner or SAS Forecast Server, then your project files are automatically stored on the SAS Server and count against your personal 5 GB storage quota.

    The Upload feature within SAS Studio is used to perform file uploads. For more information about uploading course data or SAS program files, refer to the Step-by-Step Guides.

  • Can I point to local SAS data sets or files using a LIBNAME or a FILENAME statement?
    No. The SAS Server is unable to access or recognize the local drives of your PC. If you write a LIBNAME statement or a FILENAME statement that references a local directory path, you will receive processing errors.
  • Why are some SAS Library icons white and others yellow?
    When you try to open certain SAS Libraries using SAS Enterprise Guide or create a data source using SAS Enterprise Miner, some of the available SAS Library icons might be colored yellow and others might be colored white. The library icons that are shaded yellow represent assigned libraries. Library icons that are white represent unassigned libraries. By default, when you expand an unassigned library by clicking on it, or assign it by right-clicking on it and selecting Assign, SAS Enterprise Guide assigns the library and the icon should change from white to yellow.
