Yup. Put the job in debug and try again. I am willing to bet that the
message that the ODP was re-used will appear.

Since you prepared that statement for the cursor, you are using dynamic
SQL, not static. Remove the prepare and that may help, just use a host
variable instead of the substitution in a prepare.

Of course, this assumes that you can do that.  

For example

select a from b where c = ?  ==> prepare and open cursor

--- or ---

select a from b where c = :host-var  ==> no prepare, put in declare cu
cursor for... statement

change the host variable, open the cursor and make sure it is closed
after the call.
