Hi
I'd like to know if there is a way to specify different transaction
isolation levels for different tables in the db. The reason i'm asking
this (rather bizarre sounding, i know ;-) ) question is the following:
I'm importing about 2 million records into my application each day (the
data is more or less fully replaced each day). My importer updates only
a few tables (about 5 - 10), but reads a lot of other tables (10 or so)
while...

Hello.
I am developing the application (VBA&ODBC, to be exact) which
periodically calls the stored procedures in the IBM DB2. A few of the
procedures require executing with isolation level RR ( ANSI
"SERIALIZABLE" ), not the default; default is CS (ANSI "Read
Committed")). The procedure language is SQL.
According to the documentation, I can adjust procedure *run*-time
isolation level by setting *compile*-time dataserver-wide option

I am redesigning an application that distributes heldesk tickets to our
50 engineers automatically. When the engineer logs into their window a
stored procedure executes that searches through all open tickets and
assigns a predetermined amount of the open tickets to that engineer.The
problem I am running into is that if 2 or more engineers log in at the
same time the stored procedure will distribute the same set of tickets
multiple times.

I have a question about the "readCommitted" transaction isolation level.
I have a client that is updating a record on a table.
I suspend the execution after the UPDATE but before the commit statement.
Than another client is trying to read the same record.
As transaction isolation is set to "readCommited" I expected that the second
client will read the old version of the record (before the update).
Instead, the second client hangs and...

Hi,
I have 1 SQL statement selecting data from various tables and updating other
tables.
The question then is how do I prevent other applications from modifying the
tables that I'm working on (that is while my transaction is being executed)?
I know that the isolation level should be either REPEATABLE READ or

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,...

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...
