Dear Colleagues,
We don't have any experiences with 64 bit operating systems (both M$ and Linux) with PVSS.
Could somebody send me any advice about the whole possibilities of the newest PVSS with 64 bit server operating systems?
I mean, if You have any experience in this theme, send me information about the advantages and disadvantages.
Thanx!
Janos

Re: 64 bit operating systems with WinCC OA 3.10 SP1
Hello.
WinCC OA 3.10+SP1 is still a 32 bit application.
The next major version will be also available as a 64 bit application. Then the advantages of a 64 bit system can be used.
The following article gives you an overview about the differences between a 32 and 64 bit operating system:

Re: 64 bit operating systems with WinCC OA 3.10 SP1
Hello!
Thanks a lot for the quick answer! Of course we are familiar both with 32 and 64 bit operating system (at home I use Xubuntu 11.10 64 bit and - unfortunately - in our company we have to use M$ W7 64 bit, what isn't a good idea in the Simatic environment...)
So, the released version remained 32bit based.
Do You have more detailed information, when expectable the 64 bit version for Linux and M$? Or I could ask our test engineers at evopro...
We have a new project in Dubai (in the development phase, about 70000 IOs), in which we planned before using 64 bit M$2008 Server on the redundant server-pair (because from Your sales we heard that for M$ 64bit already implemented the PVSS..).
That means, we have to use the old 32 bit variant of the operating system - it isn't a good news, it will reduce the system performance because of the installable/applicable RAM...
Thanks in advance,
Janos

Re: 64 bit operating systems with WinCC OA 3.10 SP1
Hello Janos,
the new version of WinCC OA - 3.11 - what will be released begin of July, is already a native 64bit application.
As you already stated in your previous post all available operating systems are now 64bit only.
Therefore, when quoting for an upcoming project please consider using the new version of WinCC OA: 3.11.
(Nevertheless you could also run any 32bit application on a 64bit OS as well, for example 3.10.1 on Win2008 Server R2 or Win7 64bit).
best regards
Markus

Re: 64 bit operating systems with WinCC OA 3.10 SP1
Hello!
Windows 2008 R2 64 bit is officially supported by WinCC OA 3.10+SP1. You can use this operating system for your project.
I do not know if Windows 2008 R2 is available as 32 bit version. Even if it is available this type is not officially supported.
As 3.10+SP1 is still a 32 bit application it does not use all the benefits of a 64 bit operating system has.
The planned release date for the upcoming version 3.11 is beginning of the third quarter 2012.

Re: 64 bit operating systems with WinCC OA 3.10 SP1
Just to make things clear: PVSS 3.10.1 is also certified on Linux 64bit RHEL5
For a redundant server pair, where performance, security and reliability is important, I'd definitely recommend to use Linux.
One advantage I see when running 32bit apps on a 64bit OS is the larger RAM availability across all processes in sum and the per process available RAM is larger due to the fact
that the kernel can use the additional RAM in a 64bit OS
The 32bit address space limitation for each 32bit process still remains, though.

Re: 64 bit operating systems with WinCC OA 3.10 SP1
Thanks a lot, Martin!
Since we have decided using Oracle server for long term archiving we also interested in Linux 64 bit on the server pair - but the customer wants just M$ servers - probably because they haven't any experiences with Linux...
Strange situation, but what to do?
So, thanks in advance, Colleagues - probably everything is clear for me

Re: 64 bit operating systems with WinCC OA 3.10 SP1
I am looking forward to see how WinCC-OA 3.11 performs on a 64-bit platform. Am I correct in thinking that if I run WinCC-OA 32-bit in a 64bit Windows OS today, each process gets access to 32bits (~4GB) of RAM or is this just the case on SPARC architectures?

Re: 64 bit operating systems with WinCC OA 3.10 SP1
Hello Jonathan,
yes, you are correct, but the ~4GB RAM is the system wide limit that is valid for all processes together.
One single process is allowed to consume 2GB RAM (what is, for normal, more than enough for the event manager...)
There will be two different setups available in 3.11 one 32bit (what will be useful for client installation),
and one 64bit setup where all the manager are native 64bit applications.
The systems memory limit on Windows 2008 server R2 on 64bit hardware architecture:
standard edition: 32GB
enterprise: 2TB
(Windows 7: 192GB)
best regards
