Hi all,
I have an application that uses Oracle's JDBC thin driver 9.0.x to
have a nice, friendly chat with 8.1.x database. During this exchange
the server rudely interrupts the conversation and causes the
application to fubar. The driver reports this as 'Connection reset'
(IOException) without any error numbers. The server is hosted by a 3rd
party in one of those "controlled" environments so my first guess is
network/tx timeout but...

I've created a data access layer for a .NET web

an error from time to time when I close a connection
saying: System.InvalidOperationException: A connection
pooling error has occurred.
It doesn't happen each time, the exception is thrown
randomly. The big problem is that the connection is left
active in the pool. After a short period of time, the
pool is filled up and people...

Our web application running on WebSphere hits the following two
exceptions randomly (once or
twice a day) while opening connection to db2. Does anyone has idea
about the cause of the exception. We are using connection pool to
connect to db2.

Hello All,
Some time ago, I implemented a data access layer that included a simple
connectin pool. At the time, I did it all by myself: I created N
connections, each connection associated with a worker thread that would
execute the db commands. The pool was fixed and all the connections
were created when the db access class was instantiated. The
connections remained opened during the whole execution. If a connection
was not available...

I am using VS2003 and connecting to MS Access database.
When using a connection pooling (every time I open the OLEDBCONNECTION I use
the exact matching connection string),
1. how can I know how many connection has been used ?
2. If the maximum pool size has been reached, what happens when I call the
method Open to open the connection ? Will I get an error ? MSDN says the
request is queued, but will I get an error in the open method ?

I am using VB.NET 2003 and SQL 2005.
To use connection pooling and avoid the error "There is already an open
DataReader associated with this Connection which must be closed first." , I
understand that I want to release/close connections in a timely fashion.
What I do is I declare the SqlClient.SqlConnection variable as a local
variable inside my subroutine (instead of a global variable). Right before I
Fill the dataset I open the...

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 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...
