A few days ago, I was working at a customer and made a few changes to the running listener’s configuration.
After having verified that my changes were working as expected, I asked the listener to save the configuration, but the result was quite unexpected.
The listener crashed with TNS-1153.
I had hit bug #8612344, which is affecting all 10.2 versions running on Windows, including the 10.2.0.5 which my customer is using.
In short, I had to restore a listener.ora configuration file, as the current file was trashed – it was now 0 bytes in size now.
Luckily, I had taken a backup of the file before starting, so the fix was easy.
