Is there a way to determine the entire defined range of tapes size in RMM  ?

x3270 can save as text or HTML.  The HTML is an excellent full-color
representation of the screen and searchable, not a bitmap.

When the only tool you've mastered is printscreen, everything
looks like a bitmap.

In my worst nightmare, that HMC would scrape its own screen and
make a .PNG available to the browser.  Saving the page might just
capture an anchor to a volatile image.

For mainframe issues at the terminal, sure.  But in other cases I might
want an image, such as last week with a new z15 that wouldn't IPL and I
asked to see the HMC screen.  Turns out the solution was pretty easy
once I saw the error - nobody had connected any FICON cables yet.
That'll do it :)


May I in infer, then, that:
o The HMC (they never let me touch one) has only graphic screenshot
   capability, not text?
o The HMC is inaccessible via emulator?  Good security; hindrance to
   darkened/remote computer room operations.

Otherwise I can't envision a graphic screen image as superior to text.


As Dave noted HMC is accessible directly or remotely, but in both cases 
it is browser.
IMHO remote access is better, because it's easier to make screenshots 
and manage them.
And this is HTML, so you can prepare set of pictures and/or the messages 
as text. I created several instructions and used both. Sometimes it's 
better to show the picture and sometimes it is better to provide only 
the message. Of course in this case the goal was to make some procedure 
easier for the reader, not an audit.
I was also a movie star during some CPC upgrade I performed, but due to 
some co-worker who disturbed me... parental advisory... yes, the 
language was coarse...

Depends.  x3270 can capture screen content as either text or
impressively realistic HTML; both quite browsable/searchable.

(But does that violate a strict definition of "screenshot"?)

Not sure about all other emulators.

It's irritating that some users report problems and supply graphic
screenshots as documentation.


In this case it had to be Windows printscreen, full screen, so it can be 
x3270, Tom Brennan Vista, PCOMM, Notepad, Paint, whatever. The result is 
always a bitmap.
For the log I mentioned it would be over 100k pictures, over 80GB disk 
space. Obviously I refused to do screenshots for that log.

That's typical of UNIX filesystems.  And the kernel does everything -- no
problems arising from inconsistent DEBs in user address spaces.  But
problematic in a shared or client-server environment.  Search for
SOLARIS NFS CLIENT CACHE
... and be aghast.  It doesn't simply work.  Better left to a caching
disk controller.

For 30+ years I perform security assessments, status audits,
readiness reviews, pentest (call it as you like). I've NEVER (!)
interviewed a person, or asked him for a screenshot. give me a standard
user (for phase one) and one with ROAUDIT (for phase two). The system knows
better how it is configed.

As lizette says, if you have not already done that (now, my suffix) by an
audit product. There are some in the market, and let them collect the
information themselves.

ZFS tuning

[Colin Paice]

Are there any good guides for tuning ZFS?  I've found some guides from 8
years ago - are they still valid?

Can I get zFS to cache directories or hot files in memory?   There are lots
of stats from ZFS, but it is hard to find the important numbers in the data.

Ive moved ZFS into OMVS
,
but it makes no significant difference.

I think this is really important and it will take place in the future. 
Or just some feedback process to report formal objections about the 
auditor and his incompetence.
I met a lot of auditors and unfortunately I observe they are younger and 
younger folks with less and less knowledge. And the audit is processed 
to avoid any cost possible.
Funny story: auditor demanded some report "as long as possible". It was 
really long - over 600 MB of text. However another demand was to provide 
everything as screenshot or set of screenshots.

Side notes:
a) screenshot can contain fake information as text file - it is enough 
to place false text file to the host and browse it.
b) screenshot series is completely useless for browsing or searching 
some string.
c) auditor did not understand the output at all. That's why he further 
asked for information already delivered on another screenshot. He just 
read some checklist and relay questions with no analysis about it's content.


Of course there are exceptions. I remember two guys, who audited me for 
two weeks. Knowledgable. If something was not clear, he asked for help - 
what command is proper to provide him such and such information. Note: 
he didn't want the output, he wanted a command to issue. And every 
"finding" was discussed - what, why, etc. The best audit I had.


And the most funny: an auditor sent by very big and very known company. 
He was really embarassed and ashamed, because it was his first week in 
this job. And it was hist *first job ever*.


BTW: I also conducted some audits, being hired as independent 
consultant. Mostly RACF, but also more general, including data center 
and some operational procedures. However my role was not to collect the 
outputs.
