I found a way to do this before, but I didn't write down how I did it, so I
don't remember it now. And I've searched http://www.mysql.com/doc/ in
vain.
What's the command to show all current locks on a database table?

Help!
I have a table that multiple processes must be able to
write to concurrently. However, it for some reason
gets locked in exclusive mode. I narrowed it down to
one SQL statement + some weirdness with foreign keys.
To debug this, I opened two psql sessions and typed in
the sql statements manually. Here is the situation:

I`m exporting data from many Lotus Notes databases to a DB2 database
using LotusScript. The LotusScript agents commit after EACH
update/insert. Nevertheless, I keep getting transaction rollbacks on
deadlock or timeout. When I get a snapshot for locks, I see that one
of the export agents is getting a table lock rather than a row lock.
I`m guessing this is what causes the time out. Questions: how do I
determine whether it`s a deadlock or a...

Hi,
we have a contention problem because of an application which tries to
insert a duplicate row in a table with primary key. This insert fails
of course but the locks are not released within this transcation.
Why DB2 does not release the X lock after a failed insert???
We use DB2 UDB EEE Version 7.2 Fixpak 9, but we also can reproduce the
Problem on DB2 UDB ESE 8.1 Linux Fixpak 4.

Is there a SQL query that can be run against a database that will give me

DB2 v7.2 (FP7 - DB2 v7.1.0.68) on AIX 5.2.0.0.
We're seeing unexpected single row (then commit) insert locking
behaviour.
We're seeing Applications that already hold row-level W locks in
lock-wait, waiting to acquire row-level X locks. The lock-waits are
behind applications that have row-level X locks on different rows
(honestly). Both executing and lock-waiting applications have been
granted IX table locks.

I'm having problem with using DAO recordset to append record into a
table and subsequent code to update other tables in a transaction. The
MDB is Access 2000 with the latest service pack of JET 4. The system is
client/server, multiusers based. The MDBs are using record locking.
Here is part of the code:

Dim rstTrans As DAO.Recordset
Set wkSpace = DBEngine.Workspaces(0)

Hi
When does DB2 go for an IS (Intent Share) lock?
IS mode is defined as a mode in which "The lock owner can read data in
the locked table, but cannot update this data. Other applications can
read or update the table."
Why are concurrent applications allowed to update the table but the
lock owner is not?
In a normal SELECT query, it is observed that DB2 goes for NS (Next

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,...
