Kill DB sessions the easy way with SQLcl

Seems I can not tweet these animated GIFs anymore. So this is another very short blog post to show real case for adding a new command into SQLcl which can be downloaded here.

It's hard annoying tedious to find SID and SESSION then alter to kill that when needed.  What if there was a simple kill command.

Here a sample one that takes in the 2 options:
  kill sid serial#
  Example :   kill 1 2
OR
  kill USERNAME
  Example: kill KLRICE

SQLcl and Query Change Notification

The database has had Query Change Notification for a while but to use it required a custom program. Such as Tim outlines on his blog https://oracle-base.com/articles/10g/dbms_change_notification_10gR2


Since SQLcl has Nashorn, now it can be integrated with a few lines of javascript to get notified when changes happen.  The script is below and posted.  The catch is QCN only works on Varchars and Numbers.
