Path names in the QFileSvr.400 file system

 

Path names have specific form in the QFileSvr.400 file system.

• The form is:

     /QFileSvr.400/RemoteLocationName/Directory/Directory . . . /Object

  The first-level directory (that is, RemoteLocationName in the example shown above) represents both of the following attributes:

  • The name of the target system that will be used to establish a communications connection. The target system name can be either of the following names:

    • A TCP/IP host name (for example, beowulf.newyork.corp.com)

    • An SNA LU 6.2 name (for example. appn.newyork)

  • The "root" (/) directory of the target system

  Therefore, when a first-level directory is created using an integrated file system interface, any specified attributes are ignored.

  First-level directories are not persistent across IPLs. That is, the first-level directories must be created again after each IPL.

• Each component of the path name can be up to 255 characters long. The full path name can be up to 16 megabytes long.

  The file system in which the object resides may restrict the component length and path name length to less than the maximum allowed by QFileSvr.400.

• There is no limit to the depth of the directory hierarchy, other than program and system limits and any limits imposed by the file system being accessed.

• The characters in names are converted to UCS2 Level 1 form when the names are stored.
