This article shows you how to configure a DB2 datasource in Apache Geronimo v1.0. Normally you would just use the Geronimo Administration Console and the creation pool wizard for this task but that method allows you to specify only ONE driver jar file. In the case of DB2 you would have multiple files, one for the driver and two additional files for the license. Now that we have our .jar files lets create a ‘lib’ directory in the root of our project and put them there. We’ll come back to these .jar files when it’s time to start talking to your DB2 database.

I have tried unplugging all but one set of drives on the expander using just a single sff-8087 to sata break out cable. So even with a single set of 4 drives connected to the hp sas expander I see this problem if I try to transfer from one drive to another. I even switched the set of 4 drives I was using so it was a new set of drives, new cable, and in a new port on the expander and the same thing happens.

The connection is bound to the session only for duration of call. The pool element is the underlying physical connection. The application sessions can migrate to any underlying available physical connection. The first version of JDBC specified using the class java.sql.DriverManager to create Connections. This turned out to be insufficiently flexible and later versions of the JDBC spec define an additional way to create Connections using DataSources.

The buffer size generally doesn’t affect performance on a noticeable level unless it is too small; 64MB is the largest we’ve seen on a hard drive excluding the hybrid SSD Seagate Momentus/Barracuda XT drives. Unfortunately, storage protocols are not as nice as other standardized interfaces where all you need is a bus and a device that speak the same language and everything’s fine. A drive not on that list may have been designed to perform optimally with a different brand of controller, and the errors you are seeing are a side effect of the optimization. You have a SAS controller, that might be the problem. While SAS protocol can be used to tunnel ATA commands the signaling at physical level is a bit different . Almost all controllers are able to speak directly to SATA drives, but if there’s a (big? crappy?) backplane in the middle the signal might be disrupted.

The comments in this file explain how to use it. There are some applications where the the Thin driver is faster, some where the OCI driver is faster. As of 10.1.0, the Thin driver is probably slightly faster than the OCI driver. In cases when the client and server are the same type of hardware and OS, the OCI driver puts a little less load on the RDBMS download IBM Drivers, even though the Thin client is faster.

We are simply going to change the default listening port of the Tomcat Server. If the test is successful, you will be informed that it has contacted your database successfully. If the JDBC driver is set up, you should simply see a message telling you the test is complete. In this step we are going to test to make sure the JDBC driver was set up properly during the previous step.

A small bump of a metal drive on a hard counter can be 70 Gs. The drive is traveling at perhaps 1 foot per second, and then it comes to a complete stop in less than a thousandth of an inch. «I’ve got to wonder if the problem isn’t the drives necessarily, but bad handling…» I had purchased one from a wholesaler that sells to small-time vendors, and it was an OEM model. I took it back, got another, and this one’s been happily running for about ten months. Yeah, it’s quite common on SCSI drives, less so on IDE…

What you need are the drivers for your sound card.What card do you have? The next few restarts, the computer gave all sorts of long «system file is missing or corrupted» errors. No matter what keys I press, it refues to boot from CD, and after a few seconds it spits out the message «System file is missing, press CTRL-ALT-DELETE to restart».
