Hi All!

We have some issues regarding downloads to OS Servers (PCS7 6.1 SP1):
1. Cannot perform a full download to Main OS Server. Simatic Manager hangs after 'all' files are transferred. Manually transferred WINCC project on Main Server.
2. Full download runs fine on standby server.
3. Redundancy also performing well.
4. Impossible to make a delta download.

User rights for host drive are set for SYSTEM and SIMATIC HMI groups, identical for both servers.

Where are we doing wrong?


Thanks!

The main problem that should be tackled first is why you cannot perform a download to one of the servers. How did you transfer the project manually? Using the project duplicator? In this state delta download will not work properly. If one machine works and the other doesn't, most likely it’s an installation/setup issue.

Any way, take a look at the following FAQ; it may solve your delta loading problem.

Why doesn't OS delta load from the SIMATIC PCS 7 ES work despite Runtime being active on the OS station?

Unfortunately, the solution with CCAgent is said to be ' valid for PCS 7 versions V6.0 SP3 + Post SP3 Fixes and earlier '. CCAgent is running as process and cannot get that configuration screen out of it.

'Manual transfer' means copying the project as-is from ES to OS Server. I've found no other way to do it. Didn't use project duplicator.

Do you get an error message after download is complete?

May be there is a lock file (LCK) that needs to be deleted.

Did you see the following FAQ's? I found them very useful while troubleshooting server problems.

After reloading the OS project to the server from the ES, how do you clear the undefined error message and the abort?

How can you clear the error message "Download (310:88)"?
http://support.automation.siemens.com/WW/view/en/22559073

Which messages may appear in the "Download OS" dialog box?

How do you use the SIMATIC shell to configure the terminal bus of a WinCC station?

Try this:

At the Main Server:
  1. Shut down WinCC Exporer and WinCC Runtime
  2. Execute the script Reset_WinCC.vbs (in the PROG FILES\SIEMENS\WINCC\BIN folder)
  3. Navigate to the directory on the Main Server where the OS project is installed
  4. Delete the folder and all its subdirectories
  5. You shouldn't have to, but may want to reboot the server.

    At the ES:
  6. Do a full download from the ES
Hopefully it won't hang. 
If you don't have the right user privileges on SQL Server, you can't even get to a download.
Manually transferring projects has pitfalls because of data, network and directory mappings being renamed in the transfer process.

I've tried almost everything without success. The issue with 'hosts' said in the following link 

http://support.automation.siemens.com/WW/view/en/22019649

is applicable in my case? This is the only thing I haven't tried.

Thanks!

I presume by your reply that you did do all those steps exactly in that order.  If not, do them.

New Questions:
Is the main server used for any other system/application?
Are there users who may log into the main server?
Do you have only ONE, repeat that, ONE instance of WinCC running on the server?

If there are unknown shares, conflicting applications or users active on the system when you are trying to download, run, or do other things on the Server, it can behave erratically, make you think you are crazy, and convince you the software is terrible.

And lastly, is this a new installation, or is this a server that has been running for some time, and now has problems?
If it's been running for some time and now has problems, what changed? 
(I'm not implying you did anything to change it)
Were there any network events that may have preceeded it?

The servers run since two months.
This is the second complete download performed after being forced to create another OS due to a WINCC compilation error 15424.

http://support.automation.siemens.com/WW/view/en/22019524

Before complete downloading the new OS it was possible to make delta downloads, but no OS compilations.

Yes, it is an existing installation. Yes, I've tried all suggested combinations. Weird is that the complete download runs fine on Standby server.
No, except WINCC there are no applications running on the servers (2003 SP1). The only clients are the configured WINCC clients. What exactly means 'one WINCC instance'? Never seen as possible to have multiple instances. The only thing is that I still keep the old project stored on the servers. On the main server (the one with this problem) I've downloaded the project, interrupt Simatic Manager on ES after half hour of waiting to finish, delete wincc.lck on ES+server, reset wincc and launch WINCC.

And again, both servers are, in this very moment, up and running. No delta download possible.

Oops, my bad.  I meant to write SQL Server.
I have seen multiple instances of WinCC running also, but that was when multiple remote desktop logon sessions were active on Windows Server.

If you keep the original OS project stored on the Main server, it still exists in the SQL Server database (the instance of SQL Server running is a local instance only - essentially a more powerful version of MSDE), and as such, this can create your whole problem for you.  For some reason, the original OS was a corrupted database - by keeping it on the server, the corruption may still exist and affect other databases - meaning the one you are currently running.
I've seen rogue databases (improper configuration settings, SQL scripts caught in a loop, etc) on SQL Server completely disrupt the function and accessibility of ALL the databases on that server (and in one instance, the server was virtualized to boot).

This then opens the possibility that what you have is one of those flukes that you can waste weeks trying to figure out.
The simplest solution (in my opinion), is to remove your licenses, wipe the server completely, reinstall Windows Server 2003 SP1 and rebuild the PCS7 installation.  i.e. start fresh.

If other tries won't work, first thing in the morning.

Thanks!
