hi all

any solution for this scenario.

1)I have a master site and local site.

2)Materialized view is refreshed at local site... and the results are stored in a cache which Java uses .

3)Any request for the mview data is retrieved from cache.

4)Now I am refreshing matview again using fast refresh.. i.e only records that are changed in the master is updated at the local site.

5) I have to flush the cache .. while flushing i have to flush only those records that are changed.... coz full flush is not good and i have to recache the entire data if i do full flush

My Question is How to identify the records that changed....so that I can only flush those records from cache..

I want to identify the changed records........any ideas you get please.. share with me....

sorry i dont know the differences between the two types..
does the approach change if we are using one of them?

how about this ..

adding a column called Indicator_flag and mark them to 'C' if any record changed and allowed them to propogate to local replicas.

but if the answer is this simple if would have been implemented before itself..

am not sure about this answer.

please suggest

Regards
Raj

According to your statement; Your using Complete Refresh from pl-sql code or Java Code.

If you provide exact details; We will try to solve your problem
