2 data records were deleted in sql and a commit was executed. These records need to be retrieved. How can I
restore them?

First time using experts exchange, please bear with me.
We are using oracle 8i, I have very little experience with
oracle administration and would need a detail step by step walk through if possible.

Do you have a backup of the database? Does that backup contain the two rows you need?

If you do, you can clone the database to a new server, recover it to a point in time before the deletion occurred (like one SCN just prior to the COMMIT statement for the delete), then copy those two rows from the clone back to the original database.

The following document provides 15 database recovery scenarios - including this situation (scroll down to Scenario #8):

To summarize, if you have a database export available, then re-importing the data would generally be the quickest method.
