Hi,
I have these 2 problem? Is there a way in Oracle to read UNCOMMITED
data. i.e. in Oracle the normal behaviour is that a user's updates to a
table are visible to other users ONLY when the user commits. But in
Informix there is this thing called ISOLATION LEVELS. For example by
setting the ISOLATION LEVEL to DIRTY READ, a user will read dirty data,
i.e. the last uncommited updated value of a field by some other user. Is

I have a question about oracle commit and transactions. Following scenario:
Process A performs a single sql-INSERT into a table and commits the
transaction. Then he informs process B (ipc) to read the new date. So
process B starts "select ..." but does not get the previously inserted
row. The timespan between commit and select is very short.
(NOTE: two different sessions are used)
Questions:
1.) Does commit when returning from call...

Hi,
I would like to start a new process and be able to read/write from/to
it. I have tried things like...
import subprocess as sp
p = sp.Popen("cmd.exe", stdout=sp.PIPE)
p.stdin.write("hostname\n")
however, it doesn't seem to work. I think the cmd.exe is catching it.

Hey,
I am currently attempting to implement a multi-threaded C# socket,

this works.

This seems like a pretty straight forward thing to do, but I just can't get pyUSB to install properly. I download the .gz file from SourceForge and run the normal "python setup.py install". I get this message:

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,...

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
