Local Path

Use this type of path to obtain the data from a file or a set of files located in the same directory. This path can be:

  • On the local file system of the Virtual DataPort Server (not to the local file system where the Administration Tool is running)
  • On a Windows shared drive accessible from the host where Virtual DataPort is running. Note that the user account that launches the Server has to have privileges to read this file.

To enter the path to a file, we recommend you to click the Browse button, enter the path in the File name box and click Ok. The reason for this is that in Virtual DataPort some characters have a special meaning and have to be escaped. By doing it this way, these characters are automatically escaped.

Instead of specifying the path to the file, you can use interpolation variables (see section Paths and Other Values with Interpolation Variables) if you do not know the path to the file at the time of creating the base view and you want to provide it at runtime.

For example, you can enter the path /tmp/datafiles/@REPORT_ID.txt. The base views created over this data source will have an extra field called report_id and at runtime you will have to provide the value of this field in the WHERE clause of the query.

Paths Pointing to a Directory

The File path can point to a file or to a directory and it can be in the local file system or in a Windows shared drive.

When you create a base view over a data source that points to a directory, Virtual DataPort infers the schema of the new view from the first file in the directory and it assumes that all the other files have the same schema.

Only for delimited-file data sources: if the path points to a directory and you enter a value in File name pattern, the data source will only process the files whose name matches the regular expression entered in this box. For example, if you only want to process the files with the extension log, enter (.*)\\.log.


For XML data sources, if a Validation file has been provided, all files in the directory have to match that Schema or DTD.
