Re: iASP security

The promotional material associated with IASPs seems to be over-reaching -
at least to me. They promote partitioning disk units between tenants. That
leads to running more disk drives without much in return, as far as I can
tell. I seem to recall Power HA relying on it.

I recall reading that when you vary off an IASP, you can no longer use the
Libraries (or SQL Schemas) associated with it.

It seems to me that Libraries already offer a suitable means of separating
tenant data, without needing to assign disk units to each.

The "help" associated with INLASPGRP says that the SETASPGRP command can be
used to change the thread's initial setting.

That's what I am trying to figure out. iASP is being declared, by IBM, as
a good SaaS-model-way to separate out multi-tenant situations (i.e. same
named libs but different iASP). What I am trying to determine is if this
SaaS they are talking about was in a situation where the user didn't have
access to a command line and instead it was only through a browser. I shot
an email off to IBM but also wanted to get community input.

Hello,

I have some iASP security questions I hope someone can answer. Let me

lay

out a scenario:

*Scenario*
- I have a single IBM i instance, let's call this IBMi1
- I have two IASPs configured, IASP1 and IASP2
- I have two users configured, USR1 and USR2 (QSECURITY=30,

USRCLS(*PGMR))

- USR1 has a *JOBD with INLASPGRP(IASP1)
- USR2 has a *JOBD with INLASPGRP(IASP2)
- I have two libs, LIB1 is in IASP1 and LIB2 is in IASP2
- I have two RPG *PGM objects, RPG1 is in LIB1 and RPG2 is in LIB2

When USR1 logs into a IBMi1 5250 session (and inherently placed in

IASP1),

can they see or attempt to invoke LIB2/RPG2 in IASP2 if the authority

is

*PUBLIC(*USE)?

Can USR1 see or invoke IFS files in IASP2 if files are set to chmod

go+rx?

I would test this myself except I am having issues setting up the

scenario

on IBM's PDP
<

https://www-304.ibm.com/partnerworld/wps/servlet/ContentHandler/stg_com_sys_power-development-platform

service
(I have an email into support). I would try iASP on the variety of

other

servers I have access to, but I don't want to accidentally hose

anything

:-P

Thanks,
Aaron Bartell
