Tip from: scotte@cdsac.uucp (L. Scott Emmons)
The ksh has an undocumented way of binding the arrowkeys to the emacs line editing commands. In your .kshrc, add:
alias __A=^P alias __B=^N alias __C=^F alias __D=^B alias __H=^A
Note that "^P" (et al) must be the actual control sequence.
Type "set -o emacs" or put this line in your .profile.
Also, you MUST have PTF U406855 for this to work in AIX 3.2. The APAR # for the problem is IX25982, which may have been superseded.

You want to create a CD with those long filenames like: cluster.es.server.rte.4.5.0.9.bff? Transfer all files to a "temp" AIX directory..
inutoc . # in the "temp" dir. cd .. mkisofs -o myimage.iso -R temp
..et voilą, an image you can write with your favorite CD writer - which can be on a PC if you tranfer the ISO back.
Why this workaround?
AIX is using the standard ISO CD format and adheres to the 'Rock-Ridge' extensions to support long filenames, etc. This is what all Unix machines do. Unfortunately Microsoft decided that it needs its own CD format and invented 'Joliet'. Most PC software only supports 'Joliet' and not Rock-Ridge, Nero is no exception.
However, there is an excellent workaround: The 'mkisofs' utility takes your files and creates a CD-image (.iso) including the Rock-Ridge table of contents. You can then write the iso file to your CD. Just search for mkisofs and start fiddling with its commandline-switches.

Number of bytes per inode:
NBPI * 2 ^ 24 Example: ((65536*(2^24))/1024^3) GB = 1TB
Fragment Size (in bytes):
frag.size * 2 ^ 28 Example: ((4096*(2^28))/1024^3) GB = 1TB
NBPI ranges depend on the Allocation group size:
ag=8 512, 1024, 2048, 4096, 8192, 16384 ag=16 1024, 2048, 4096, 8192, 16384, 32768 ag=32 2048, 4096, 8192, 16384, 32768, 65536 ag=64 4096, 8192, 16384, 32768, 65536, 131072

Here we create an mksysb with the aide of sudo. In combination with the sudo command we use "su -", that way we have our "ulimits" and complete "root environment" available. Then we try to transfer it "secure" to a remote server where we do not have remote root login previleges but we do have sudo access. The result: my personal users file-limit is 2GB on both servers and with this method i can create AND transfer larger mksysb files in a secure environment!
sudo su - root -c "mksysb -pe /var/local/backup/mksysb/hostx.mksysb" && \ dd if=/var/local/backup/mksysb/ hostx.mksysb bs=8k | \ gzip -1 | \ ssh -x wva0331@nimmaster sudo su - root -c "dd of=/nim/images/hostx.mksysb.gz bs=8k" && \ sudo rm /var/local/backup/mksysb/hostx.mksysb

Yes, you can do this on AIX by default. An equivalent for this is ttysnoop - but i never tested that one. Here is an example, but for the details see the man page.
# ask remote host for his/her pts by typing: tty # ask remote host to open a subshell: ksh $ portmir -t pts/8 -m pts/4 portmir: Remote user connected, mirroring active. ... $ portmir -o # Closes mirror (attention - remote shell will be closed!).
If you change the groupid of a group you also have to change the files. But for links people often re-create them. If you just use the -h option there is no need for that!
# change file and directory rights ..
$ sudo find / -group 235 -exec chgrp opc {} \;
# change link rights ..
$ sudo find / -group 235 -type l -exec chgrp -h group5 {} \;
IBM stanza files like /etc/qconfig and /etc/security/user have line lenght limit of 255char. For qconfig this means that you are limited in the number of devices per queue. The number of queues however seems to be unlimited.
The vi version included has a limit of 2048char. Use vim for editing longer lines.
The maximum number of users in /etc/group is limited to 2000. The line lenght is defined in /usr/include/grp.h. Here is the calculation 8+((8+1)*2000)+14=18022.
A NIS record has a maximum size of 1024bytes. This limit applies to all NIS maps including maps for /etc/group, /etc/netgroup, etc... While creating the dbm (make or makedbm), it uses the line along with the domainname and some other fields, a safe config line lenght is 1000char.
qconfig device names (in /etc/qconfig) are cut to 20char and get a prepending "@"-sign . If you have the hostname "config-server-aix-01" it gets cut and becomes "@config-server-aix-0"!
Logical volume Name of the logical volume. Logical volume names must be unique systemwide and can range from 1 to 15 characters.
Volume group Name of the volume group. Volume group names must be unique systemwide and can range from 1 to 15 characters.

In case of mirroring allocation problems or the need to free-up 1PP/disk to convert a VG to a BIG-VG you might need to move a single Physical Partition. There are 2 commands (AIX53) that can help you with this: migratelp and lmigratepp.
SYNTAX: (no leading zeros, copynumbers are 1 to 3)
migratelp LVname/LPartnumber[/Copynumber] DestPV[/PPartNumber]
EXAMPLE:
$ migratelp movemelv/1/2 hdisk12/134
SYNTAX:
lmigratepp -g VGid \
-p SourcePVid -n SourcePPnumber \
-P DestinationPVid -N DestinationPPnumber
EXAMPLE:
$ lmigratepp -g 00582b6a00004c000000010e514b6f61 \
-p 00584d2a5e4d8e41 -n 0134 \
-P 00584d2a14dfdc7e -N 0001
Note: to choose your destination PPnumber you can use the output of `lspv -M hdiskpower14`.

In the past, a high wait I/O was a good predictor of a bottleneck. However, today it's a bit more complicated. High wait I/O may not imply an I/O bottleneck. You'll have to consider other factors, which is listed below.
The reason high wait I/O may not be a good predictor is because CPU performance has significantly outpaced disk performance. Here's a situation that illustrates the point while replacing an older server with a new pSeries server. The new server has 6x the CPU performance (SAN storage stays the same). After the upgrade, wait I/O increases from 33% to 70% during batch jobs - the following table shows what happens.
Variable Old Server New Server
====================================
Rel CPU Perf 1 6
Wait I/O 33% 75%
Batch Times:
CPU Time 40 min 7 min
I/O Time 20 min 20 min
------ ------
Total Time 60 min 27 min
The server upgrade improved CPU performance, but not I/O performance. The faster CPU's were able to do their job faster, hence they spent a higher percentage of their time waiting for disk I/O. Since batch time decreased by half the high wait I/O isn't a real problem. If you do not have anything to compare (upgrade and historic performance data) against it is harder to show and prove this.
Hints:
AIX53 LDAP users management (TL5 also includes AD enhancements)
If lsof reports nothing, fuser without parameters reports nothing, then try:
fuser -dVu /dev/somelv
In smitty you find the following line:
User can LOGIN REMOTELY(rsh,tn,rlogin)?
It changes the rlogin attribute
lsuser -a rlogin <user>
From /etc/security/user
* rlogin Defines whether the user account can be accessed by remote * logins. Commands rlogin and telnet support this attribute. * Possible values: true or false.
From man rsh: "If you need to execute an interactive command on a remote host, use either the rlogin command or the rsh command without specifying the Command parameter. If you do not specify the Command parameter, the rsh command executes the rlogin command instead."
Note on Secure shell: The attributes (like rlogin) only affect the ssh and scp commands if the "UseLogin" attribute is set to "yes" in the ssh daemon configuration file on the server.
Usefull references:
The rlogin attribute does not affect rsh (or remsh) *with* command parameter specified. It does affect rsh *withouth* command parameter becourse then the rlogin client is actually triggered. At this time the rlogin attribute only affect rlogin (same as rsh withouth command), telnet and Secure shell if the UseLogin attribute is set. Knowing this, the part inbetween backets in "smitty user" is, at least, misleading!
To controll rsh *with* command parameter (and also rexec) you should use the rcmds=deny option in /etc/security/user.
rcmds Specifies whether the user account can be accessed with the rsh
or exec commands. A value of allow indicates that the account may
be accessed by rsh and rexec. A value of deny indicates no
account access by rsh and rexec commands. A value of
hostlogincontrol indicates that the account access is controlled
by hostallowedlogin and hostsdeniedlogin attributes.
rcmds=deny rexec, rsh, rcp, ssh, scp
rcmds=hostlogincontrol and
hostsdeniedlogin=<target_hosts> rexec, rsh,
rcp, ssh,
scp, rlogin,
telnet, ftp,
login
Note: rcmds disallows execution of remote commands. Remote logins (rlogin) are still permitted. So to completely block rsh you need to set both the rlogin attrinbute and the rcmds option.

The mirscan command (introduced at 5.3 TL 3 I think). Note that this will generate significant amounts of I/O and takes a verry long time to run!
mirscan -v vgname | -l lvname | -p pvname | -r reverse_pvname [ -a ] [ -o ]
[ -q nblks ] [ -c lvcopy ] [ -s strictness ] [ -u upperbound ]
-a Specifies that corrective action should be taken.

No! All UNIX variants show you the access time of the file, modification time of the file and change time of the inode. Every time you change permissions or update the file inode this time is changed. for database files you will notice that all dates are the same :(
istat, ls -li + fsdb or the perl stat function might be useful to you on AIX.
