title: Alternative Method to Polling/Trigger a Table in Oracle?
body: <p>I have a db on Oracle 11g where there's a table updated by external users. Now I want to catch the insert/update/delete on this table in order to bring these changes on a table on another db and I'm trying different methods for research. I tested polling (a job to check every minute if there is an update, insert or delete on the table) and trigger (fire on update, insert or delete on the table) yet, so are there alternative methods?</p>
  
  <p>I found AOQ (Oracle Advanced Queuing), DBMS_PIPE, Oracle SNMP Agent Integrator Polling Activity, but I don't know if they are right for this case...</p>
