Phased upgrade IWS 8.6 to 9.3 with Sysplex - workload-scheduler

Running SYSPLEX with sysid SXX1 and SXX2. SXX1 is running OPC controller and OPC tracker while SXX2 is running only OPC tracker.
Planning to IPL only SXX1 to upgrade the version from v8.6 to v9.3 while OPC at SXX2 still running v8.6. Do you see any problem with this arrangement?
Will only IPL SXX2 for OPC new v9.3 after a few days the S1M1 running with the new V9.3

workload scheduler for z/OS is designed to support this scenario. So no problem is expected if you proceed as you described. Katiuscia Berretta (IWSz development)

Can I used Step7 as PLC simulator?

I have PLC program written in Step7.
Also i have SCADA with OPC Server.
I want to simulate PLC with programm from Step7 and connect it to OPC Server, because i want SCADA testing.
Can I used Ste7 as PLC simulator, how can i do that ?
I founded some blog where what tutorial how to config Step7 and simulator, but doesn't work, this was very old tutorial.
As an alternative solution to the fine one from tonteria2424
You could try to load the program into a virtual S7-1500 and activate OPC-UA ..
Follow this 7 virtual steps (step7)
Download trial versions of simatic tia portal from
https://support.industry.siemens.com/
Google "S7-PLCSIM Advanced trial"
and "tia portal trial"
You need "STEP 7 Professional V14" SP1 + updates
and "SIMATIC S7-PLCSIM Advanced V1.0 SP1"
Then you can load your program into a virtual plc, connected to a virtúal network adapter and use the opc server(in the virtual plc) as a datasource for your scada and test it for 21 days.
PLCSim Advance can do networking, so testing can be close to "real life".
I have tested this setup many times.
if your scada cannot do opc ua... that was covered by the first answer ;)
(I did not know that NetToPlcSim was opc da capable)
//PerD
Please go the support Site of Siemens and narrow down your question. It is far too open.
But I guess that this might be your answer.
PLC SIM (for 300, 400 and 1200 and 1500) does not support externel connections. Only internal to their HMI/Scada on the same host.
I did what you want using PLCSIM + a free software called NetToPlcSim simulating S7 300.
I used Simatic step 7 v5.5 I don't know if it still works with newer versions

High Memory usage by Java (TM) Platform SE binary

We are noticing that IBM MobileFirst Server is using High Memory by Java TM Platform SE binary process, after 2 3 days of server start it reach up to 6 GB which cause the server in hang status, then only restart is the solution.
in logs we found below message:
"No buffer space available (maximum connections reached?): connect"
Enviornment: IBm Worklight Server 7.1 and java version is 1.7 64 bit on windows server 2012. hybrid Mobile application running on this server.
It seems that there might be some configuration required can any one advice ?
Lots of information missing... this can be caused by any number of reasons.
Are you in a cluster? if yes, how many servers? how much memory is available to each machine?
How many adapters do you have deployed? What is the value you gave to the serverSessionTimeout property? This for example can cause connections to stay open for a longer time, meaning the server will not "clean/remove" connections... and the more you have open, the more memory you will require.
all of these and more can contribute to how much memory you may need.

It mentions DB2, but the idea is - the more connections, the more memory you will need.

Hyper-v network driver not signed

I've recently moved a Virtual machine from a server to another one.
Both the servers are running Windows Server 2012 R2 as the guest host.
The generation 2 VM run almost perfectly, but it doesn't recognize the network adapter.
Integration services are updated (if I try to re-install it it says they are already updated and doesn't let me repair it).
On device manager I see the exclamation mark left to the adapter.
If I let it search for drivers in C:\Windows it says that the "Network adapter for Hyper-V" is found, but it isn't digitally signed, so it won't be installed.
Anyone could help me making this adapter work?
I couldn't figure out how to remove and re-install integration services either...
Ok, I found a solution.
I had to Disable Driver Signature Enforcement in the advanced boot options.

IBM WAS 8.0 to 8.5.5 migration

I am asked to upgrade IBM WebSphere application server 8.0 to 8.5.5 on linux environment. Could you please give me a step by step guide for this migration?
thanks,
Kumar
The simplest method (assuming your WebSphere instances have enough spare CPU/disk/etc) is to build a second WebSphere cell at the new level and migrate applications across one at a time. Access to the application servers should be controlled by either a web server (using the WAS plugin) or an IP sprayer product and which version of app server used should be controlled in that layer. Updating in place has many pitfalls and can be difficult to recover from if something goes wrong which can lead to extended down time for your applications.

is Redis stable on Windows?

This afternoon, I used python script to test the performance of Redis on Windows.
It worked normally when the number of threads was only 10, but some exceptions occured when the number of threads reached 100.
Exception message:
3 [main] redis-server 1448
_cygtls::handle_exceptions: Exception: STATUS_A CCESS_VIOLATION 1394 [main]

Is Redis stable on Windows?
Redis is not officially supported on Windows. Some unofficial ports exist (such as the one you're using), but I believe stability is not guaranteed for these ports.
Redis prime dev Salvatore Sanfilippo ('antirez'), December 2011:
I don't think Redis running under win32 is a very important feature. It is cool to have a win32 port that can be used for testing, as we had before, and as we have in a different implementation thanks to the Microsoft patch, so developers using Windows can easily test Redis and develop their projects. But what is the point in providing a production quality win32 port?
Regardless, parties within Microsoft are still improving the Windows build
Here’s to the first release from MS Open Tech: Redis on Windows
Claudio Caldato 26 Apr 2012 12:01 PM 8
We consider this not to be production ready code, but a solid code base to be shared with the community to solicit feedback: as such, while we pursue stabilization, we are keeping the older version as default/stable on the GitHub repository. To try out the new code, please go to the bksavecow branch.
The Redis download page now says "The Redis project does not directly support win32/win64, however we look at interest to projects trying to make a win32/win64 port that is separated from the main project...Currently both ports are not production quality but can be used for development purposes..."
We maintain a stable and production ready Windows port (native!) of Redis.
The Developer Edition is free.
Check out Memurai.

I use it in my projects till last month and didn't experience any problems yet.
