Virtual File System

TIBCO BusinessConnect uses a UNIX-based Virtual File System (VFS) to present the operation of each protocol in BusinessConnect combined with virtual folders, such as Inbox and Outbox, to facilitate file downloading and uploading. In this system, each file belongs to an owner, and each owner belongs to a group. In this concept, the owner is the external user who logs on to the FTP Server, and the group is the trading partner with whom the external user is associated.

While in BusinessConnect it was assumed that the user ROOT creates folders and that these folders belong to ROOT, the FTP Server uses a virtual file system.

Folders used for TIBCO BusinessConnect Plug-In for FTP Server are virtual folders and cannot be deleted.

File permissions are created such as in UNIX: read, write, and execute (R, W, X). In addition, this virtual file system has to be structured so that it is compatible with the one used by TIBCO BusinessConnect, with the file structure such as:

Inbox

   EZComm

      BC

         1.0

            Notify

User permissions for accessing files are granted to the Owner, Group, or others. Usually, the permission levels are more restricted for levels above the Owner. An example of permissions granted to owners and groups is presented in Table 1.

BC 1.0 Notify (Inbox)	When the protocol was last modified	rwxr-xr-x	root	root
