Hello freaks,
we have many problems with our online reorg and no idea how to resolve
it.
We had to do an online reorg beacause of 24 h online business.
We start the reorg-statements (table by table) in a loop with the
following statement:
reorg table xxx.yyy inplace allow write access.

Here when many users are trying to update the same table the dead lock

level in my table, so that the dead lock situation will not arise.

I launch a worker thread that periodically reads a volatile bool
abortRequested, which could be set to true by my main form.
IOW, there is one thread that can read that bool and one different
thread that can set it. See code below for an overview.
In a C or C++ environment, my current approach would be
adequate (no need to acquire exclusive access to abortRequested).
I'm guessing that I'm still OK under C# because bool is a value
type....

I think I'm seeing table-level lock contention in the following function
when I have many different concurrent callers, each with mutually distinct
values for $1. Is there a way to reimplement this function using
select-for-update (or equivalent) in order to get a row-level lock (and
thus less contention) while maintaining the function interface? The docs
seem to suggest so, but it's not clear how to return the SETOF queued_item
and also...

I got great info on related question previously. This link
<http://www.yoda.arachsys.com/csharp/threads/volatility.shtml> from Brian
Gideon was especially informative.
1) the lock statement does *not* make the processor finish all code in the
code block before giving another thread from your process a slice of
processor time, it only makes sure other threads cannot run the same code
*if* they also adhere to the same lock object....

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
