I'm stumbled stuck with the following scenario:

Oracle db running on a solaris server.

I want the database to actively and immediately send some kind of message to an external application whenever a given table has been updated. This should preferrably be done using sockets or anything similar. The reason for this is that I can't afford having the application poll the db since that would mean too high a load on the network (If the external application should poll the db, this would have to be done _very frequently_ since the external application I'm developing must be as realtime-based as possible).

The oracle db in question does not have any support for java (old version of oracle). Now, I'm a beginner to pl/sql, but was wondering if I could solve my problem (that is, getting the db to send a message to my external application whenever a table is being updated) using pl/sql? Does anyone have other suggestions on languages/techniques to use?

I would be very grateful for any hints pushing me in the right direction, or any comments to my problem at all :)
