Overhead executing 32-bit routines in 64-bit Instance

P: n/a
In my current environment, we have a 64-bit instance (DB2/AIX64 8.2.4)
where we have at least one function that was left in 32-bit mode (not
JAVA). According to the IBM documentation it is possible to invoke
these functions with a performance degradation at first, I assume from
the libraries not matching at first.
>From an administration perspective what should I monitor to ensure
memory is being handled properly? Also, I've observed that some
routines that are invoked by this 32-bit function are NOT FENCED and
ARE THREADSAFE, which is counter to what IBM suggests. Is there a way
to monitor for failure in calls to these routines?

As a DBA, I would prefer this code be fixed immediately, but what
happens if this stays as-is? It's a very large DB with a lot of
traffic. There's not much documentation on how all this relates, so
any advice would be appreciated.
