Impact of Creating new index ?

User_OCZ1TJul 21 2012 — edited Jul 23 2012
Hi All, I am using 10.2.0.4.0 version of oracle.

I want expert advice in below scenario.

I need to create one index, as because a particular 'Search' query going slow and my customer frequently accessing that 'Search' Functionality. i have tried all alternative for tuning that query, and finally decided to go for creating New Composite index on two columns of a table that is used in the query.

So my question/concern is , what will be the impact on other 'Select' queries those are using these columns in their predicate? Whether there is any possibility of any negative impact(slow performance) on them due to this new index. What should be the right way to go for impact analysis in the above scenario?

( Please note in this case i am least bothered about the impact on 'INSERTS' due to this index creation).
