I belong to an Oracle discussion list (oracle-l) and just last week someone mentioned that they had debugged a Java app that was having performance issues and found the same thing - when a procedure parameter is defined as CHAR, something (probably the Oracle driver but I don't think the guy ever determined that for certain) was padding out the field to the full possible length of a CHAR.
I wasn't paying that close attention but I think his solution was to switch back to VARCHAR2. If that's possible in your case it might be the easiest fix.

Hi,
since I had a pause of over 1 year in WO development I guess this is a rookie question… At least I hope so. (I'm pretty sure I'll be ashamed after your answers.) :-)
Our database experts changed the interfaces of some stored procedures we're forced to use. ;-) Mainly they modified some string parameters and changed the type from VARCHAR2 to CHAR (length was/is defined as 10 chars for either solution). I thought that I only had to change my EOModel in order to reflect these changes. So I switched the parameter type from VARCHAR2 to CHAR and didn't touch the width definition (10).
Now after executing the "new" procedure with EOUtilities.executeStoredProcedureNamed the result was surprising (especially to me): the expected 10 chars String had a length of 32512. I checked the "old" (VARCHAR2) procedure and got the expected 10 chars. What am I missing? (Is this the revenge for not developing with WO for so long? ;-))
We're developing with WO 5.2.3 on Windows XP (Eclipse/WOLips), Oracle Thin connecting to a remote Oracle 9i.
Since I'm stuck I'd appreciate fast help!
TIA,
Stephan.
