Metalink 387394.1 also has a good description of the problem. If the query is just coming from a perl script, your best bet might be to change it to use literals instead of bind variables. Other possible solutions are:
  • Remove histograms on the involved tables (gather stats with method_opt=>'for all columns size 1')
  • Stored outlines
  • SQL Profiles (10g+ if you have Tuning Pack license)
  • Upgrade to 11g and see if Adaptive Cursor Sharing fixes it or try using SQL Plan Management to preserve the good plan
