7.7.1 Providing UCX Emulation

UCX$IPC_SHR is an executive-mode logical name pointing to a shareable image supplied by your TCP/IP vendor. If this logical is not defined, then either TCP/IP is not installed, or, in the case of a package other than DEC's TCP/IP Services for OpenVMS (a.k.a. UCX), UCX emulation was not installed when the package was installed. In order to use the TCP/IP functionality of PMDF Pine, this logical must be defined and be pointing to the appropriate image for your TCP/IP package. Moreover, the image must be installed as a known image,


$ INSTALL UCX$IPC_SHR /OPEN/SHARED

If you are running Pine on a system without any TCP/IP software, a dummy shareable image PMDF_EXE:UCX_DUMMY.EXE is provided with PMDF. Your system manager should define a system-wide, executive-mode logical named UCX$IPC_SHR which points to it and then install it:


$ DEFINE/SYSTEM/EXEC UCX$IPC_SHR PMDF_EXE:UCX_DUMMY.EXE
$ INSTALL UCX$IPC_SHR /OPEN/SHARED

Note

If you install any TCP/IP package later, remember to deassign the logical name or you won't have a functional TCP/IP.
The definition of the logical and installation of the image should be made part of the system startup procedure. Note that the installation of the image can be effected through the site-supplied PMDF_COM:SITEIMAGE.DAT file which uses the same format as the Process-supplied PMDF_COM:PMDFIMAGE.DAT file.
