Also this app needs to do a count(*) of the tables every 10 minutes for verifying some application based logic. This is really killing us and it takes a lot of time. Can you please guide me to a direction ( built in functions or something similar). Actually this app is being ported from Informix. Informix can somehow keep a trak of the count(*) of a table in its header somewhere. And yes I have tries count(1) , count(indexed_column) etc. Thanks In Advance.
