machines? In our case, we used histograms on indexed columns and that
brought execution plans same on both the database.
Look for analyze command syntax to build histograms.

hi Srini,
Why don;t you use stored outlines.

Yes they both are, only difference being the amount of data in Prod and DEV
databases for this query. Prod has more.

Thank you for the response. The indexes on both sides are regular non-unique
indexes. Any other possible reasons..

Are they both using the same optimizer?
I would state that "obiviously" something is different
between the two instances; otherwise you'd get exactly
the same results.

The frequency of when a script should be run depends entirely on what the
script does.. For instance - You may have a script that looks for space
bound objects within your database (can't throw their next extent),
depending on the number of objects within your database, this could be a
REAL KILLER
When I took over the position of Oracle DBA I inherited a number of scripts,
including some
tuning scripts. Plus through this list and meta-link I have found a number
of resources about
tuning, What I am unsure about is when to capture the information required
for tuning decisions
