Hi,

For an unknown reason, lpd and printq users, printq group were deleted on AIX. Now, we want to reinstall bos.rte.printers fileset but need to restore, users, group and all file permissions of commands of this fileset.

Question, how can we reinstall and reconfigure bos.rte.printers from scratch? Is it possible?

Hi,

You can reinstall bos.rte.printers by performing an "overwrite same or newer ..." installation of the base level (!) fileset and applying all subsequent TL updates and the latest SP up to the desired level. Please note that an automatic installation of requisite software is not supported along with "overwrite" - and again - it must be the base level fileset!

Users/groups and permissions should come back with the installation, as well as the relevant ODM subsystems and security attributes (for /etc/security/privcmds).
Even if users and groups wouldn't come back along with the installation - it should be quite easy re-adding the lpd and lp users or the lp and printq groups, respectively using the numeric ids found on an intact AIX system:
lpd user/printq group: 9, lp user/group : 11
Afaik there is no "printq" user!
When users/groups are removed then owner or group of concerned files will show up as numeric ids, but ownership will not change.
Re-adding the users/groups using their previous ids will make the files show up again with "real" owner/group names.

bos.rte.printers does not contain the full directory structure found under /usr/lib/lpd and /var/spool/lpd, so if you need to restore things like predefined printer attributes, smit menus etc. consider reinstalling this fileset as well.

To help decide what's required/missing check with "lslpp -f bos.rte.printers" and "lslpp -f printers.rte" what these filesets have to offer.

Cheers
