GETUDC Operation
GETUDC is an MPE V/E utility that aids you in migrating your MPE V/E User
Defined Command (UDC) environment from an MPE V/E-based system to an MPE/
iX-based system. GETUDC is designed to be used by System Managers (users
with SM capability) who are preparing to migrate an existing MPE V/E UDC
environment to an MPE/iX-based system using DIRMIG.
The GETUDC utility places in a text file:
* The name COMMAND.PUB.SYS, a system file that keeps track of the
names of all system-recognized UDC files, as well as the users
associated with those UDC files.
* The names of all system-recognized UDC files located on your MPE
V/E-based computer system.
NOTE A system-recognized UDC file is one that a user has specified with
the :SETCATALOG command as being either a system-level,
account-level, or user-level UDC file.
You should use GETUDC immediately before creating the SYSDUMP tape you
are planning to use with DIRMIG. When you run the MPE V/E SYSDUMP utility
to create the tape, you can enter the name of the GETUDC-generated file
at the following SYSDUMP prompt:
ENTER DUMP FILE SUBSETS
Using the GETUDC-generated file as an "indirect STORE file" (a file
containing valid responses to the above SYSDUMP prompt) ensures that
files are placed at the beginning of the STORE portion of the
SYSDUMP tape in the order you specified in the indirect STORE file
(COMMAND.PUB.SYS followed by UDC files).
When migrating the MPE V/E UDC environment to an MPE/iX system, DIRMIG
invokes the RESTORE facility twice; once to restore COMMAND.PUB.SYS, and
once to restore UDC files whose names DIRMIG reads from COMMAND.PUB.SYS.
Placement of COMMAND.PUB.SYS and UDC files at the beginning of the STORE
portion of the SYSDUMP tape greatly reduces the amount of time DIRMIG
takes to search for and restore these files.
