I am having more than 100 database. Each database contains some tables. After performing some operation tables in database got updated. Currently am running a thread which will connect each database and check whether any updation is done or not. Its working fine now. But my need is if am having approximately 300 database and last update will occur in some database only. In this case i dont want connect all database and check. How can i done this. I want some efficient way to do this???
