As others have noted, indeed it doesn't. I (and others) have repeatedly had to 
explain to skeptical MVSers why it's A Good Thing for z/VM. Just because z/OS 
doesn't know how to exploit it, they think it must be useless...

Yes, Linux can use it, with the xpram driver, but with VDISK around, there's no 
real need to use it.

Re: XSTORE

2009-03-04 Thread Tom Duerbusch
I like the idea of a dynamically configurable parm for xstore.  It would make 
it easier to test "tuning" options.  Could be something like the SET MDC cache 
command.

The only thing I've gleamed from the whole XSTORE for paging thing is that it 
helps with block paging out.  We demand page in, no matter what.

While it's true that CP no longer pages out any parts of the nucleus itself, 
there are CP owned pageable structures that may be paged out on the target 
volume.  The bulk of these are pageable PGMBKs (normal user private space 
PGMBKs, containing the page tables that represent user storage), but there are 
some other pageable structures that are not tied to users, so even if all users 
were logged off, there's no guarantee that paging use on the drained volume 
would drop to zero.  =

What release of VM:Secure are you running?  In r2.8 G0808, it definitely
doesn't work.  I tested before I posted.  You're assuming that LOGON and
LOGONBY rules are evaluated together to determine the most specific
rule.  That's not how it works.  LOGON rules are evaluated first.  If
the userid cannot be logged onto, LOGONBY rules are irrelevant.

Subject: Re: [IBMVM] Using LBYONLY


I am sorry, but that set of rules WILL work in VM:Secure.

To quote the Rules Manual:

When two or more rules in a file govern a particular access request, 
VM:Secure establishes an order of preference based on how precisely
the requester is specified. 
In order of preference, a rule is chosen that indicates: 
1.A specific user ID as requester 
2.A specific group as requester 
3.An asterisk (*) as requester; this indicates all user IDs


So, when someone NOT mentioned in the specific ACCEPT
rule tries to logonby, the REJECT * LOGON catches them.
But if the user specified in the accept attempts it, the ACCEPT
rule is more specific and will allow the logonby.

In fact, the manual gives an example just like Richard's rules,
except that it is dealing with LINK requests:

REJECT * LINK 191 RR
ACCEPT FRAISERC LINK 191 RR

While it's true that CP no longer pages out any parts of the nucleus 
itself, there are CP owned pageable structures that may be paged out 
on the target volume.  The bulk of these are pageable PGMBKs (normal 
user private space PGMBKs, containing the page tables that represent 
user storage), but there are some other pageable structures that are 
not tied to users, so even if all users were logged off, there's no 
guarantee that paging use on the drained volume would drop to zero.

SFS question (was: Q LIMITS question)

2009-03-04 Thread Gentry, Stephen
Is there a command of some kind or has anyone written an EXEC (or PIPE,
etc.) that will provide a list of SFS directories that a user has access
to?

Have a look at my SFSULIST package.  Basically it displays a combination
of Q LIMITS, Q ENROLL AMDIN,  Q FILEPOOL CONNECT and Q FILEPOOL STORGRP

Don't' put the period '.' after MAINT.   I just tried it and it worked
for me.

Hi,
I am a bit confused by a Q LIMITS situation.

1) I (XMSL) am an admin:
 q enroll admin vmsys
NUMBER OF ADMINISTRATORS =18
MAINT
XMSL

RMSMASTR
DGTSRV01
DGTSRV02
DGTSRV03
READY; T=0.01/0.01 19:37:54

2) I can query limits of ALL the users:
 q limits all vmsys
USERIDSTORAGE GROUP  4K BLOCK LIMIT  4K BLOCKS COMMITTED  THRESHOLD
DFSMS 2450090-02%   90%
MAINT 27000  3030-43%   90%

READY; T=0.01/0.01 19:39:10

3) BUT... I canot query an individual user:
 q limits for maint. vmsys
USERIDSTORAGE GROUP  4K BLOCK LIMIT  4K BLOCKS COMMITTED  THRESHOLD
MAINT.-   - - -
READY; T=0.01/0.01 19:40:13

Why not??

Thanks for any suggestions,
Shimon

Long ago, in a galaxy close to where I am this week, there was a PGP

Recently, PGP got interesting again (to me).  Actually, GPG is what I
use instead (for better or worse).  So it occured to me that when there
is a face-to-face opportunity, such as that enjoyed by those fortunate
souls who made the trek to Central Texas, the subject of key signing
should be kept in mind.  Therefore, if you happen to be in Austin this
week and have a GPG key and want a signature, let me know.  At least,
let SOMEONE know.  (My signature may not be what you need, and I am okay
with that. But ... get yer keys signed!)

Re: Using LBYONLY

2009-03-04 Thread Shimon Lebowitz



I am sorry, but that set of rules WILL work in VM:Secure.


To quote the Rules Manual:

When two or more rules in a file govern a particular access request, 
VM:Secure establishes an order of preference based on how precisely
the requester is specified. 
In order of preference, a rule is chosen that indicates: 
1.A specific user ID as requester 
2.A specific group as requester 
3.An asterisk (*) as requester; this indicates all user IDs



So, when someone NOT mentioned in the specific ACCEPT
rule tries to logonby, the REJECT 
* LOGON catches them.
But if the user specified in the accept attempts it, the ACCEPT
rule is more specific and will allow the logonby.


In fact, the manual gives an example just like Richard's rules,
except that it is dealing with LINK requests:


REJECT * LINK 191 RR
ACCEPT FRAISERC LINK 191 RR

We still use it with CMS20 (haven't access to anything later), the versio

that was ported by Konstantin Berdichevsky from Phil Zimmerman's excellen

product.  No updates since 2001.  Yes, MIT is still running VM, but it's 

been outsourced to another datacenter near New York City.
