Is Your Sequencer Giving you the Cold Shoulder?

There are few other things in this world more frustrating than getting the cold shoulder for a reason you can’t even guess. Is your sequencer’s data collection software giving you the cold shoulder? And by cold shoulder we’re actually referring to the yellow triangle status. 

This is a fairly common problem that can be explained by a multitude of causes, luckily we have a solution. Some of the most common times we see this is when the computer name has been changed or incorrectly changing the settings on the computer can lead to this mishap. In order to ensure that the computer name is set correctly, follow these four easy steps.

Step 1: Right click on My Computer-properties; you will see the full computer name.

Step 2: Go to the folder shown in the picture below and you will find two files, “listener.ora” and “tnsnames.ora”.

Step 3: Open “listener.ora” and “tnsnames.ora” with notepad. The name after “HOST=” should be identical to the “full computer name”

Step 4: Reboot the computer and the sequencer, and try launching the Data Collection software.

Once you are able to complete the above steps, your computer and sequencer should be working in perfect harmony. If these steps did not work, or your Data Collection is still being stopped by this troublesome yellow triangle, it's time to call SeqGen for further advice. We would be more than happy to help figure out an alternate solution to work for you and your machine.
