JDBC Adapter Query performance

It seems some SQL statements are getting “hard parsed” per execution. A trace file shows the number of execution is equal to the number of hard parses.

Any ideas?

Thanks in advance,

The integration is selecting and inserting mutiple records during a single activation (sub).
