I'm writing a postgres database with a PHP front end
for a small work-group , and I want to prevent two editors
working on the same record at the same time overwriting each
others entry's.
The standard solution is to add a lock field to the
database and toggle it from 0 (unlocked) to 1 (locked) when the
record is selected for editing, however I cannot guarantee that a
record will get unlocked when an editor has finished with it (a...

hi, we are using db2 udb v8.1 ESE with type 4 jcc driver. since DB2
can't support pessimistic locking , and our application required that,
which means when both users try to access the same record with intent
to update, the first one grab the record will create a row lock on the
current row reading, before it update, other user can't access the
same record with intent for update read, but can access with read only
type. so when the first...

I have an A97 table with a Yes/No field named
TowJob and a form bound to that table. The
TowJob control on the form is bound to the same
field. It is an option group with Yes and No bttns
valued at -1 and 0 respectively.
Unless I specifically set the table field's defaultvalue
to Null, the form comes up with an automatic value
of 0 in the control? The control has NO default
value property setting. Why is that?

When is it appropriate to use "volatile" keyword? The docs simply
state:
"
The volatile modifier is usually used for a field that is accessed by
multiple threads without using the lock Statement (C# Reference)
statement to serialize access.
"
But when is it better to use "volatile" instead of "lock" ?

Hello all,
I am running with DB2 UDB V8 on AIX.
I am trying to track down what appears to be a lock issue. I turned
EVENT MONITOR on with all the options. It doesnt give me the detailed
information I need for tracking who is holding the lock. Here is what
I get in the event monitor:

The Delete Event/Proc & "Save_Fields_In_Form_Header" Event/Proc in
my form were working perfectly.
However, after I added a call to the "Save_Fields_In_Form_Header"
Event/Proc in the "Current" Event of my form, and I now try to Delete
a record, I get ... Run-Time Error 3218 - Could not Update; Currently
Locked. My Access application then effectively freezes forcing me to
shut Access down & re-start.
The record DOES get deleted...

Excuse my noobness. I am managing an access database that is shared
by 4 users. Management does not want to use any technologies outside
of access for this application (no SQL Server, etc). I have split the
database into front end and back end databases and put the front end
on each of the users' computers. All users can open the front end
simultaneously, but once somebody updates data in the form, the back
end locks up.

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.

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...
