Re: Interesting - NODE for z/OS

2018-02-21 Thread Timothy Sipples
The IBM SDK for Node.js probably won't run on your z9BC machine, but you're
welcome to try it. (Please let us all know.) The latest trial download is
available here:

https://developer.ibm.com/node/sdk/ztp/

APAR UI46658 is surely required, so check for that.

If you're looking for a JavaScript implementation (without Node) for a z9BC
machine, I believe HostBridge's HB.js is compatible.

Re: Interesting - NODE for z/OS

2018-02-21 Thread David Crayford
We've been using Node for internal tooling and IBM have done a good job. 
The Node eco-system is the fast growing of any language/runtime. Like 
I've said before the most exciting thing from my perspective is the 
clang compiler that ships with it.


One important feature that makes Node so scalable is libuv and it's 
async I/O. IBM have emulated epoll using standard poll so I can't see 
how it's ever going to scale like it does on other platforms. It's 
curious why they didn't use aio like the pollsets in the z port of the APR?

Two summer time change questions

2018-02-21 Thread Charles Mills
First though, apologies for asking what perhaps has been covered before --
perhaps even asked by me. I am having no luck searching the archives. I
search on CVTTZ and get no hits even though I have IBM-MAIN messages in my
own Outlook that contain CVTTZ.

1. Humor a guy with almost no operations experience with the world's most
newbie operations question. If you are a shop in North America, how will you
"convert" your z/OS instances to summer time next month? Do you or does your
console automation software have to enter a SET command, or does it happen
automagically internally to z/OS on some pre-configured schedule? (I
remember I had a P/390 back in the day and VM had an internal table that did
the time change automagically but I recall I had to re-IPL OS/390 to pick up
the change.)

2. When the above happens, will CVTTZ and CVTLDTO get updated on the fly? If
I inspected them one second would I see an offset of, e.g., 8 hours (in TOD
or "TOD-high word" format as appropriate) and if I inspected them a second
later I would see 7 hours?

We need to do something similar. My recommendation for 'at the same time' is to 
first allow CYL_MANAGED by command, then when the dust has settled, activate 
the new level. This can be done during the same Change Management window, 
minutes only, but it might minimize the churn.

​Thank you for that link. One difference that I can see is that the above
mentions a "Free 90 day trial"​ and I must sign in to ShopZ to get it.
Whereas the source pointed to in my original messages does not have any
mention of a "free trail" period or any requirement to use my IBM id to get
the software. Not that it matters to me personally, because it is unlikely
that the IBM offering will run on my company's ancient z9BC. I'm running
into that a lot any more. And management here basically refuses to get a
more current machine.

I haven't really had a chance to look at this yet. But I thought others
here might be interested. It is NODE for z/OS. NODE is a "server side"
JavaScript engine. That is, it allows you to run JavaScript programs on
z/OS.

Re: Dr. John Ehrman

I worked with John back in the 90s when I was part of the languages
group that he headed at Share. I always made it a point to attend
his pitches as they were full of information that I could use and
the hand-outs were always excellent. I just found that he had updated
his excellent "Assembler Language Programming for IBM z System Servers"
book:

http://idcp.marist.edu/enterprisesystemseducation/assemblerlanguageresources-1.html

I'm proud to say that I contributed to this. I found what I think 
is the smallest error possible in the version one of the book. There
was a table where the bits were described for floating point values
and one of the bits was wrong. :)

He will be very missed.

We have situation where a lot of data sets are incorrectly cataloged to HSM 
MIGRAT2. For an individual case, I can try HDELETE. If I get the message that 
data set is not migrated, I can issue DEL NSCR.

However we have thousands of these. We can CSI list them by data set name

Any suggestions for how to handle an enormous number of these?

I knew John from my involvement with SHARE assembler committee, and through 
work with IBM's Federal Systems Division in the 1980s. He was a true gentleman, 
always kind, very smart, and an absolute pleasure to work with. I was delighted 
to have been able to chat with him (for the first time in years) at SHARE in

Problem moved to an outage by XCF recovery?

2018-02-21 Thread Vernooij, Kees (ITOPT1) - KLM
Hello Group,

Last week we had a problem which ended in a full Sysplex outage. 
After extensive searching, I think it was XCF recovery that moved the Sysplex 
to the total outage.

We run a 2 site Sysplex, with PPRC mirroring between the sites, with Primary 
Dasd in SITE1, with our main production LPARs at SITE1 and GDPS to monitor the 
sites.

Due to a 'mistake' all Ficon connections between the 2 sites were removed, but 
the InfiniBand connections remained active. So DASD mirroring was interrupted, 
but XCF communication remained working.  
This result unexpectedly in: all SITE1 LPARs down and all SITE2 LPARs full with 
unrecoverable problems.

After analyzing all logs, we think the following happened:
- After the last connection between the centers was removed, SITE1 LPARS still 
had access to the Primary Dasd and SITE2 LPARs lost access to the Primary Dasd. 
InfiniBand and XCF connections were not hit. There were several hang in 
applications, e.g. JES2 Checkpoint Locked etc., but nothing fatal yet.
- GDPS declared a FREEZE AND GO. This did not change much, SITE1 still had 
access to the Primary Dasd and SITE2 remained disconnected from the Primary 
Dasd.

But then:
- XCF on the SITE2 LPARs detected it lost access to the Primary CDSs and moved 
to the Alternate CDSs.
- XCF on the SITE1 LPARs were notified of the CDS switches but since they had 
no access to the new Primary CDSs, they all loaded a Waitstate 0A2, reason code 
010: XCF lost access to all couple data sets.
Now we ended up with a situation, where our main SITE1 LPARs which still had 
access to the Primary Dasd were brought down and the SITE2 LPARs without access 
to Dasd were left over.
The only thing remaining was to RESET all SITE2 LPARs and re-IPL the SITE1 
LPARs.

Evaluating this makes us conclude that:
- XCF helped the Sysplex into a total down, because of the SITE2 reaction on 
the loss of access to the Primary CDSs.
- In SFM we specify that our SITE1 LPARs have a much higher weight than the 
SITE2 LPARs, but XCF does not make an SFM analyses, but simply reacts directly 
to the CDS loss event.
- If the Primary CDSs were located in SITE2, the opposite would have happened: 
SITE1 lost the Primary CDSs (in SITE2), switched to the Alternates (in SITE1), 
which were inaccessible to SITE2 LPARs and they would then load a Waitstate 
0A2-010. 
This is the way we would have liked the situation was solved.

The GDPS manuals have some statements about the location of Primary and 
Alternate CDSs, but does not declare a hard recommendation, only a 'logical 
configuration'. 
However, in the GDPS CDS configuration panels, the NORMAL configuration defines 
the Primary CDSs at SITE1 and the Alternates at SITE2. We did not find how we 
can change this.
Furthermore, GDPS Monitor1 checks the CDS orientation and from Hyperswap tests 
we know that it complains with GEO2643W if we do not change the CDS orientation 
after Hyperswap.

Should it become a CDS configuration requirement to locate the Primary CDSs at 
the Secondary Dasd site and Alternate CDSs at the Primary Dasd site?
Did I overlook something?

Regards,
Kees.
