We just went through a similar problem.
Our problem was that we didnot define the dbspace used for temp storage
as a temp dbspace. the problem we ran into is that complex queries (any
query using a temp table) would generate a temp table that would be logged.
since these tables are created by the engine itself you cannot control the
logging. the only way to prevent them from being logged is to use a temp
dbspace for temp storage. Informix told use this is a "feature" of
7.11 and this is the only way around this problem.
I hope this helps....
Good Luck...
