On the forum of PL/SQL Developer there was a message by my good friend Erik van Roon. He was having trouble with Reconnecting. Even my plugin didn’t help him. I figured I should update the plugin.
The plugin wasn’t really updated since its first version. Only some cosmetic changes, like adding new buttons.
I have decided to make use of all the features of the newer versions of PL/SQL Developer. The new version now has multiple options. First of all, the Reconnect Main option, which is similar to the way it always worked. New options are Reconnect All, which reconnects all the sessions and Reconnect Single to reconnect a single session.
If you want to download the new plugin, go to the plugin page.
