Use

By defining a directory set you specify the arrangement of the physical files that belong to a single extract. You list the directories in which to store the various physical files created for an extract.

Prerequisites

Create all the directories you intend to include in the directory set. Create these on the application server using its operating system tools for creating directories.

Procedure

See the directory set and the data volume topics for a discussion of how many volumes you need to create and how to arrange the physical files using these volumes.

  1. From the main DART menu choose Configuration ® Data extracts.
    The Display settings for data extraction screen appears in display mode.
  2. Choose Display<-> Change to place the screen in change mode. (You can do so also after going into the next screen.)
  3. Choose the File directories tab for specifying directory sets.
  4. Choose Create directory set.
  5. Enter a name and a description for the directory set, and choose Enter.
  6. At the Directory set screen, enter the list of directories to include in the directory set.

The amount of free disk space is displayed in MB on this screen.

  1. Enter the directories in the order of the volumes they are associated with: enter the directory specification for Volume 0 first, then for Volume 1, and so on.

    You do not need to enter a number at the volume ID column: the system automatically assigns a volume ID to each of the directory paths you specify.

    To insert an entry into the list, mark the entry and choose Insert line.

    To delete an entry from the list, mark the entry and choose Delete line.
  2. Enter the full path of the directory name in the Directory column.

End the directory name with a forward slash or backslash as appropriate for the operating system of the application server.

Each time you add an entry to the directory set, the Total data capacity (MB) field changes to reflect the potential capacity of the directory set. This potential capacity is calculated by multiplying the maximum file size by the number of data extract files that you are assigning to directories. It does not take into account any physical or other size limitation of the directory or directories into which you are assigning the various files.

Use the total capacity figure to check that you are defining enough volumes to accommodate the data extracts that you expect on your application server. Compare the total capacity number with the estimates for data extract size you have obtained with the File Size Worksheet.

  1. Choose Enter to see the assignment of volume ID to the directories you have specified.
  2. Choose Save to save the definition of the directory set.

Let DART users know which directory set they should use for data extracts.

You can change the definition of an existing directory set in the same manner.

From the File directories screen you can go to the File path syntax to define the syntax for constructing the complete file specification for data extract files.
