OpenExtensions for z/VM "Q"s and "A"s
Question:
When I issue ls -l the user and group fields show up as
numbers, rather than the user or group names. What's wrong?
Response:
The UID and GID numbers are stored with every file. The ls
command looks up the user name and group name by functions that get
information from the security (for example, RACF) database. If the
UID/GID does not exist in the security database, then ls
displays the number in the field.
This is a fairly common situation with directories that are pax'd on one
system and unwound on another system, where the numeric UID/GID values
are different.
When RACF searches for a nonexistent UID/GID, the search is much
slower than a normal RACF call. So you should either change the UID/GIDs
to ones that exist in the database, or add the new ones to the RACF
database.
