You might want to check and see if the SCSI adapter is terminated.  Or if there
are SCSI peripherals attached and/or piggy-backed, check for termination there
also.  Also, run errpt to see what kind of errors were logged.

I know that earlier documentation recommended that ENV be set to:

ENV=${START[(_$-=1)+(_=0)-(_$-!=_${-%%*i*})]}

and

START=path-name.

This gibberish causes the script in path-name to be executed
for login shells, which look like they were invoked as -ksh, but not
for subshells.  This can improve the performance of shell scripts
significantly if the profile is complicated.

Shouldn't this man page have been distributed with the fix(es)??? There are
massive changes to the automounter options since the man page provided with
AIX 3.2 .

The automounter under 3.2.x has been a real headache for us. In the past 3
months we have installed about 3 different updates, each of which was supposed
to fix the problems (and none of which contained the new man page). We are now 
at the stage where most things work OK. The one remaining bug (that we know 
about), however, is a real problem. Our direct map entries are names in / 
(though I don't know if this actually makes any difference, and no, we can't 
change it), and using "df" causes the automounter to start mounting all 80 of 
them! Needless to say, this makes "df" useless (not to mention that you then 
have 80 more NFS mounts from all over the net!).

This works just fine on our Suns. It even works on our Convexes, which are 
running a 2-year-old version of automount! We have never had any problems with 
these Convexes and automount, but here in late 1992 it has taken IBM several 
tries to even come close to getting it right. I am not impressed.

cs has been there since AIX 3.1, if anybody cares. However, to put in a "plug"
for an interface new in AIX 3.2:

If you need a light weight semaphore, Id suggest also looking into the
msem_lock binary semaphore interface.  It uses cs to set the lock word
in shared memory. It will block if the word is already locked.
Measurements show that msem_lock is 30 times faster than semop when the
semaphore isnt already locked (uncontended case).

Otherwise, the process which contends the lock must do something. If it
it should do some useful processing, then do it. If it must sleep, then
Id recommend using the msem_lock. It is the most efficient on AIX for
multiple waiters.

Im just trying to get the word out about a little known interface that
is new to AIX 3.2 that solves a very specific problem with fast
process syncronization.  The set of interfaces to look up are
msem_init, msem_lock, msem_unlock.

Did you get the latest source from tesla.ee.cornell.edu? They used to

True in v3.1.x

False in v3.2.x
In 3.2, he just picks the larger process(es) and puts them to sleep (and 
swaps them) for a while until things improve.  A much better solution to
the problem, eh?

Date: Sat, 7 Nov 1992 12:44:34 GMT

I just spent/lost 5 hours yesterday discovering a "known bug" in AIX
3.2.x and thought I'd share it in the hope others can profit.

I was setting up and "install server," following the instructions
in the AIX installation manual, and the load of the boot images and
ptf's ("bffcreate" is the command that's executed from SMIT)
kept failing.  Each time the failure happened, the jfs I'd
created for them showed up with no space available.

The SMIT "Copy Software to Hard Disk for Future Installation"
screen clearly has the "expand filesystem if needed" option,
which I'd checked off.  Nonetheless, be warned:

THIS DOES NOT WORK.

I ended up having to work in two windows, chfs-ing the filesystem
again and again, trying to stay ahead of the load from tape.
(Naturally, I didn't want to expand it to much, so I was doing
it 8MB at a time.)  Couple of times I wasn't quick enough, and
the process had to be restarted.

After finally having gotten all the stuff loaded, I called IBM
defect support, who confirmed that bffcreate's -X option
doesn't work.  There is no fix now, and, they say, will not
be one until "the next release."  I asked if "the next
release" means 3.2.4 or 3.3 or 4.0 or what, but the
technician wasn't able to tell me.

Organization: University of Montana
Date: Mon, 9 Nov 1992 18:30:50 GMT

I'm looking for info on whether it may be possible to "regress" from
a diskfull machine to one that uses a remote /usr. I'm running AIX
3.2.2*. Basically, I have several 220's with fully configured 400M 
disks that I would now like to reconfigure for use with a remote /usr.
The only response I've been able to get from IBM support is to 
re-install the clients using "install for use with remote /usr".
This means I'll have to go back thru the painful 3.2.2 updates which 
is something I'd really rather avoid if possible.

I haven't been able to find any detailed docs on how the remote
/usr concept is implemented. Everything I've read is "do this
and it works like magic kind of stuff". Specifically, 

1. what's req'd on a client? 
   (I remember reading a posting a little while back where 
   someone was having trouble on a client because the client /usr was
   so minimally configured - the server was down and they were trying
   to perfrom maintenance on the client)? 

2. How are PTF's and updates applied to clients when updates to code
   may affect files in root filesystems (/, /etc) as well as /usr. 

3. If a regression is possible without re-installing the OS, would
   there be problems with the ODM and the VPD?

Thanks for any info.

Are you sure that you DO NOT USE Berkely-style inet initialization?? (i.e., no

to change this host's enrty in /etc/hosts.

I have just upgraded from AIX 3.1.5 to 3.2.1 (and AIXWindow 1.1 to 1.2)
on a RS6000 32h
with an ascii display only. I use an IBM RT 6150 as an X Server
with the MIT X11.R4. the X server run on the RT, and I have
aixterm, xdt3, mwm runing on the RS6000. 
I have run that configuration without problems for about a year
with AIX 3.1.5, but since I upgraded INed does not display correctly:
the frame arrond the windows that INed create is replaced by "q" 
in the horizontal parts and "x" in vertical parts. I have tried
most fonts in misc and 75dpi without succes. I even imported
some fonts from the RS6000 but I still have this very ugly
display. for exemple the enter box looks like
x^qqqqqqqqqqqqqqqqqqk
xEnter:             x
xmqqqqqqqqqqqqqqqqqqj


Any suggestion on how this can be corrected?

I am attempting to run NFS over a slip link on AIX 3.2.2 at 19.2K.  Now, I know
that slip is no way to run NFS, but I am conducting reliability and feasibility
tests for the VERY occassional use of this access method.

I am using mount -o rsize=512,wsize=512 to keep the bandwidth of the line
conserved as much as possible.

Now:  I have had some problems with corrupted files on writes to a machine
on the other side of the link.  I would like to turn on udp checksums to
increase the reliability.  I know on Sun one can patch /vmunix to turn
on udp checksums.  I have checked "no" to see if udp checksums are one of the
options and they are not.  An info search turned up nothing w/ "nfs,udp,
checksum".  But when checking "udp,checksum" it said that they could be enabled by
a C udp program.  I guess that means that I could program my own NFS or get
the source to turn them on, but that seems like rebuilding the wheel.

Anyone know if udp checksums can be turned on in AIX 3.2.2?
My SE is out of town and probably wouldn't know anyway :(

You can switch from standalone to remote /usr in the following way:

 1) Create /sbin/net.info with the following contents:

    <client-IP> <server-IP> 0 69 0 0 <netmask> 0 ent0 1

    All IPs must be numeric. The last number specifies bnc, change to 0
    for DIX. /sbin/rc.boot reads this file to configure the network 
    interface. Here we have no gateway between client and server and use
    standard ethernet.

 2) Edit /etc/filesystems: Comment out the complete /usr:-stanza and add
    a new one with your server-IP:
*/usr:
*       dev             = /dev/hd2
*       vfs             = jfs
*       log             = /dev/hd8
*       mount           = automatic
*       check           = false
*       type            = bootfs
*       vol             = /usr
*       free            = false

/usr:
        dev             = /usr
        vfs             = nfs
        nodename        = <server-IP>
        mount           = automatic
        check           = false
        type            = boot
        options         = ro,fg,hard,intr,retry=3

 3) Execute the command:

    bosboot -a -d <bootdisk> -p /usr/lib/boot/netdisk.proto

    with <bootdisk> being your bootdisk.

With this procedure we have successfully installed a 32H that runs both
as /usr client and standalone (for demos). Note that you must export /usr
with root access and read-only to the client.

Note that I don't take any responsibility for crashes and 888's :-)

Hope this helps...
