There at at least 3 problems with that idea:
- Sometimes it depends on when code was branched (in this particular case
you are likely fine)
- It can be remarkably difficult to stay away from features introduced in
newer versions - sometimes they appear by default (for example nosegment
object creation or optimizer features) - sometimes they aren't easily
determined (anyone have a list of all the changes in sqlplus in 11.2 for
example?)
- Sometimes new feature codepaths interfere with existing feature code
paths in unexpected ways.
I'd still likely recommend 11.2.0.2 over 11.1.0.7, but mostly for future
upgrade paths (there is one for the latter :) ) rather than for a set of bug
fixes. In addition if on RAC I'd urge careful consideration of 11.2 just
because of the scale of the Grid Infrastructure implementation details (some
of which seem to still be developing in the new patchset).
