The semi official shtick from Quest is that Oracle changes the log file
format rarely because the change ripples through much of the rest of the
server code. Log file format affects archiving and recovery at a pretty
basic level.
As a financials shop, I don't worry too much about keeping up with
Please bear in mind that there is one thing in a datatype being supported and another
in all functions and features of Shareplex being usable when that datatype is involved.
I am thinking about datatype long specifically.

We are working on a SharePlex project here although we are still in
test/pilot phases. We are in an apps 11i environment with an 8.1.7.4
database. So far, we have found that index organized tables are not
supported. In addition, in financials, there is a table named
hz_locations that has a UDT
This isn't a direct answer to your question, but make sure you test
logical standby thoroughly--I had to abandon the idea of using it due
to serious bugs in the apply process, and due to seriously poor
performance of the apply process.

Sounds like a bug.
If SharePlex gets an error applying SQL to the target, the table should
get marked out-of-sync and Shareplex should go on it's merry way.
Call Shareplex Support - they are usually very responsive.
