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
statement colliding with itself and only happens under very high load.
The statement is

the schema for the userlogins table is

I want to set an alert for a specific table whenever an event has
caused a deadlock to occur on the table.
I understand how to set up an alert. But I don't know which error
number to use for the New Alert error number property for a deadlock.
Or how to specify a deadlock on a specific table.
Thanks,

Here's a really weird one for any SQL Server gurus out there...
We have observed (SQL Server 2000) scenarios where a stored procedure
which
(a) begins a transaction
(b) inserts some rows into a table
(c) re-queries another table using a subquery which references the
inserted table (correlated or not)

Hi There,
I'm getting a deadlock when I have two clients running the following statement.
DELETE FROM intermediate.file_os_details WHERE file_uid = ? AND obj_uid
There is a compound index on file_uid / obj_uid.
The isolation level is UR and I have set DB2_RR_TO_RS=YES.
Any thoughts why I'm getting the deadlock ?

Hello all,
we are running a delphi application with DB2 V8.01 which is causing
deadlocks when rows are being inserted into a table. Attaching the
Event Monitor Log (DEADLOCKS WITH DETAILS) here. From the log it looks
like the problem happens when 2 threads insert 1 record each in the
same table and then try to aquire a NS (Next Key Share)
lock on the record inserterd by the other thread.
Thanks
Rohit

Hi-
We ran into some very strange deadlocks this AM, and I was hoping to
get some insight. We were running a REORGCHK on a database, and
started getting deadlocks. What is curious is that according to the
deadlock event monitor, the deadlock was between the REORGCHK process
and another client attempting a SQL execution, and the Prepare was
requesting an Exclusive lock. Is that normal? Maybe I'm reading the
monitor output...

Hi,
The bigger my C# web-application gets, the more places I need to put in the
tedious retrying block of code to make sure operations that can run into
database deadlocks are re-run (retried) 3-4 times and give up if after that
it's still in deadlock. I'm very sure that many experienced people out
there already deal with this issue somehow. Is there an alternative to it?
Thanks for your comments and suggestions.

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:
SELECT 1 FROM ONLY "public"."application_type" x

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.

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

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...
