Honestly, I didn't really expect you to, actually, follow links Anacedent provided. Perhaps just a piece of advice: next time you choose not to tell the truth, do that in a way that the rest of the people don't know it.

These "very good links" are

OraFAQ Forum Guide (no advices regarding indexes in there)
A complete Oracle documentation, covering Oracle database versions since 8i (along with IAS and Collaboration Suite documentation).

So, you have followed all of these and found many interesting stuff about indexes, but it just wasn't enough.

What do you call a "new schema"? Is it an empty schema? If so, there are no indexes there (as there's nothing to be indexed).

What kind of a tool do you have in mind, which would efficiently do something like

CREATE INDEX i1_emp ON emp (deptno);

instead of you, typing in on the keyboard? If there's, on the other hand, a lot more complicated CREATE INDEX statement (which includes a lot of typing), there are GUI tools (as TOAD, for example) which allows you to create an index by clicking instead of typing, but - I believe that one should really understand what he/she is doing, what all the options are and how to properly use them.

If your question regards a tool which will suggest the right index type, options you should use etc. (so that you don't have to think much), I wouldn't know if there's any.

There's really nothing much to add; run SQL*Plus, study use of the CREATE INDEX statement and start typing.

If the question is when to use indexes and which ones, read How to Identify Performance Problem and Bottleneck and follow the links.

Also Rosco's SQL Tuning Guide
