makemap btree /etc/userdb.db < /etc/userdb

It will create a userdb.db based in the userdb file

For PA-RISC:
-Rewind the tape
mt -t /dev/rmt/0mn rew

-Forward to the sector after the boot
mt -t /dev/rmt/0mn fsf 1

-Use tar to extract the file
tar xvf /dev/rmt/0mn etc/hosts

For Itanium2:
-Rewind the tape
mt -t /dev/rmt/0mn rew

-Forward to the sector after the boot
mt -t /dev/rmt/0mn fsf 22

-Use tar to extract the file
tar xvf /dev/rmt/0mn etc/hosts

NOTE: change “/dev/rmt/0mn” to your tape device. If you don’t know what it is, run the command “ioscan -fnC tape” do find it out.

cat /tmp/upper_file.txt |tr '[:upper:]' '[:lower:]' > /tmp/lower_file.txt

Or the following command to convert from lower to upper case:

cat /tmp/lower_file.txt |tr '[:lower:]' '[:upper:]' > /tmp/upper_file.txt

The most annoying is the other file, which apparently has the name "blank", but not quite.

There are two ways to find the real file name.,"ls -lq" e "ls -lb":

backup@root:/home/userhome/test # ls -lq
total 0
-rw-rw-rw- 1 root sys 0 Sep 23 15:48 ?
-rw-rw-rw- 1 root sys 0 Sep 23 15:47 xx
backup@root:/home/userhome/test # ls -lb
total 0
-rw-rw-rw- 1 root sys 0 Sep 23 15:48 \002
-rw-rw-rw- 1 root sys 0 Sep 23 15:47 xx
backup@root:/home/userhome/test # ls -li
total 0
17334 -rw-rw-rw- 1 root sys 0 Sep 23 15:48
17332 -rw-rw-rw- 1 root sys 0 Sep 23 15:47 xx

The "ls -lb" shows the non-printable characters with "\ XXX" where XXX is the ASCII representation of the non-printable character.
The "ls -lq" shows the non-printable characters with "???" (quantity of ? is defined by the amount of non-printable caracters).
The "ls -li" shows the file inode.

To handle this file, the best option is to use the "find".

- Using the find based on the inode:
find . -inum 17334 -exec mv {} asd \;

- Using find with "wildcards" (based on the ls-lq returned):
find . -type f -name "?" -exec mv {} asd \;

Be careful when using the find with "meta character"! If a file whose name has only one character, it will enter the result.
 

To solve it, you should:

Stop MWA:
# mwa stop

Remove all files (including the hidden ones) from /var/opt/perf/datafiles:
# rm -rf /var/opt/perf/datafiles/* rm -rf /var/opt/perf/datafiles/.*

Check if midaemon and ttd are stopped:
# mwa status

If midaemon and ttd didn’t stop, force stops them with the command kill (the PID was returned by the command ‘mwa status’).

Now, start MWA again:
# mwa start

On AIX, you can use the following commands to create an user
# mkuser pgrp='primary group' groups='other groups' home='home directory' shell='/usr/bin/ksh' gecos='GECOS' USERNAME
