Oracle Database Discussions

Hi,

I want to discuss a scenario, with which i am dealing nowadays. there is only a single table (named livecdr ) has 22-23 fields and the records are updating in every sec (on daily basis) and in 24hrs livecdr contains approximately more than 2 crore records.

Problem is that the query processing time is so slow due to large number of records and query is fetching records from a view created on livecdr table. I want to know the options, how the query would fetch these records in a short time. Firstly i did range partitioning on livecdr and then i created materlized view but the view didn't create on partition table and when i removed partitioning it was created. After view creation, query performance is much better. i also applied indexing on livecdr.

Can you please tell me, whether this approach is okay or i am doing mistake. should i create partitioning on materialized view and how would i select records from view if partitioning would be applied on materialized view. Please guide me with best approaches.

thankyou.
