Slide 73 of 80
Notes:
- SETCATALOG user needs to know the lockword, but the the user executing individual UDCs does not ever need to specify a lockword.
- Note: the POSIX shell’s “mv” command allows a new UDC to overwrite an existing UDC file that is being accessed. The result of this is that user that just logon see the new UDC file, while users that were cataloged to the original file see no difference until the re-logon. Once they all re-logon, the old file is purged by the system, since the file open count went to zero.
