Handling invalid database connections from connection pools

Edward Singleton

I am currently developing a web app using WSAD 5.1 and DB2 V7.2.8. I
understand there is a myriad of database errors related to obtaining
valid connections that are mapped directly to
com.ibm.websphe re.ce.cm.StaleC onnectionExcept ion. There are
apparently two solutions to ensure a valid connection is obtained from
a WebSphere dataSource. The first is to catch
StaleConnection Exceptions and attempt to execute the transaction again
a finite number of times. The second is to configure WebSphere to
test each connection as they are obtained. See link
http://publib.boulder.ibm.com/infoce...ion&maxHits=50
for details.

I would like to catch com.ibm.websphe re.ce.cm.StaleC onnectionExcept ion
since it is not likely that our shop will ever move our applications
off WebSphere. Does anyone know what library should be included in
the Java build path? Is this the preferred method of handling invalid
connections? I cannot seem to find any useful documentation on this
subject for WSAD 5.1. Thanks in advance.

We're stuck in the same place. The WAS 3.5 to 4.0 documentation says to
use com.ibm.websphe re.ce.cm.StaleC onnectionExcept ion, but the 5.0
documentation is silent on the matter, and of course the WSAD
documentation is useless. This class isn't in the WAS 5.0 api
documentation.

Question about database connections

The program works like this: There is a form with a button. When the form is loaded, a separate thread is started which is retreiving/updating data in the database every x seconds. When clicked on the button, data is retrieved from the database. This looks to work fine. However, sometimes after clicking on the butten to retrieve the data i got an error message (on the separate thread): "The connection is already Open"

Web app leaving SQL database connections open

The easy way to turn off automatic updates for Windows 10/11

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,...
