Based on what you've written my guess is that you are ignoring the obvious and trying to fix the trivial.

What got migrated from AIX to Solaris? Server or Client or both? What is the hardware difference? RAM? CPU? DASD? What differences in init parameters?
Which version and edition of Oracle?
Which optimizer?
If CBO were statistics run with DBMS_STATS after migration?

Unless you are being billed by the byte a bit of information would be helpful. Cryptic information begats cryptic responses.
