Jonathan,

We 'set optimization low' in a sessions that
run stored procedures.

Procedures themselves do not contain 'set optimization low',
neither sessions from which procedures were created:
we really need maximized SQL plan, we just do not
want procedures to be reoptimized 'on the fly'

My understanding (from my previous experience and from
Informix documentation), is that SPL reoptomization is
controlled by 'optimizer' setting of a session that executes
the stored procedure. Am I wrong?

It looks like, any 'heavy' alter table (index creation,
constraint creation) of our 'online' tables immediately
causes -710 on all transactional clients. These clients ONLY
access the database through SPL.

Clients are written in C++ using Informix Object Interface libraries
