Foreign Files

Similar to the scoping rules described above, you can also reference files in separate environments serviced by a different Dali. This allows a read-only reference to remote files (both logical files and superfiles).

NOTE:

If LDAP authentication is enabled on the foreign Dali, the user's credentials are verified before processing the file access request. If LDAP file scope security is enabled on the foreign Dali, the user's file access permissions are also verified.

The syntax looks like this:

'~foreign::<dali-ip>::<scope>::<tail>'

For example,

MyFile :=DATASET('~foreign::10.150.50.11::training::thor::myfile',
                 RecStruct,FLAT);

gives read-only access to the remote training::thor::myfile file in the 10.150.50.11 environment.
