The Question is:
How to instal ucx
The Answer is :
Use the VMSINSTAL tool to install the kit, the VMSLICENSE tool to
register the license PAK (if needed), and then invoke the TCP/IP
Services configuration tool via UCX$CONFIG; via TCPIP$CONFIG on
more recent releases.
Please see the available TCP/IP Services installation manual for
installation and configuration details and options. The version
of TCP/IP Services you will install will be sufficiently old that
the manuals that are on-line for the current version of TCP/IP
Services will not be entirely helpful, thus you may want to look
for a version of the manual that matches the (older) version of
the product that will be installed.
Best approach: upgrade to the current OpenVMS VAX release and to
the current TCP/IP Services release.
