ORacle Access Manager

Hello all, 

I am trying to select records from Oracle using Oracle Access Manager. I
have created embedded SQL ILE RPG programs to do this.
My cursor is defined as follows:
 C*                                         
 C/EXEC SQL                                 
 C+   DECLARE get_data CURSOR for           
 C+   SELECT   MODEL_NO,                    
 C+            CATALOG_NO,                  
 C+            DISTRIBUTION_NO,             
 C+            DESCRIPTION_1_TXT,           
 C+            DESCRIPTION_2_TXT            
 C+     FROM   EPR_VIEW_ATLAS_ITEM          
 C+     WHERE  MFG_NO = :ITEM#              
 C+     AND    HIBC_LIC_PROD_NO = :HIBC#    
 C*                             

I am able to connect to the remote system without a problem. I can
select records from ORacle when I use literals in the WHERE clause. The
problem arises when I use host variables in the WHERE clause. No records
are selected. The host variables  are defined in my RPG as Char and 15
long.  In Oracle the corresponding columns are defined as VARCHAR2 and
15 long. No errors are generated by the program. Is there a datatype
mismatch? What is the equivalent data type on the AS/400 for a VARCHAR2
?

Any help will be much appreciated......

Thanks

Ravi
