I have a deadlock that's happening on one oracle instance but cannot
be reproduced on any other. It is always caused by the same SQL

The statement is

Hi
First a simple question ...
I have a table "access_log" that has foreign keys "app_id" and
"app_user_id" that reference the "application_type" and "app_user"
tables. When I insert into "access_log", the referential integrity
triggers generate these queries:

Hi ,
I am trying to acquire a lock on a table A in exclusive mode, and this
statement gives an error indicating a deadlock or timeout
has been detected. The lock timeout value is set to 0 which I understand
is to wait for however long it takes to acquire a lock.
Also there are other processes that have acquired row level exclusive
locks on the table A when this error happened.Is DB2
throwing this error as a pre-emptive measure.

keep getting an ora-04020: deadlock detected while trying to lock object
XDB. XDNDBKDJjilnd
The statement I'm trying to issue is:
REVOKE execute on abc."descript_T" FROM PUBLIC;
I am not able to find a solution for this besides the fact of just try the operation again at a later time.
I did try it again and again throughout the day, but get the same error every single time.

We’re continuing having a problem with a production application. The
application uses ASP.NET web services and about once a day, the web services
stop responding. The only resolution is to restart IIS or wait until IIS
detects that there is a deadlock issue and resets itself. We are constantly
seeing an event show in the event log. After this event appears, IIS resets
itself and starts working again. The event is below.
Can anyone help...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

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,...

Hello
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.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
