[Mono-devel-list] Oracle ORA-24374: Fetch errors only on solaris but not linux

[Doug]

We have installed and tested Mono 1.1.7 on both Linux
and Solaris and have windows forms working on both. 
However the exact same code fails with a 
   ERROR: ORA-24374: define not done before fetch or
execute and fetch
   on solaris but works fine on the Linux machine. 
Both machines have the same Oracle version and are
connecting to the same database.  Has anyone else seen
this problem or have any ideas of how to resolve it?
  thanks
