  You need a couple extra commas to separate the options.  Try this:

START DBE 'ProdDBE' MULTI NEW
MAXIMUM TIMEOUT = 2 MINUTES,
DEFAULT TIMEOUT = MAXIMUM,
<I would also add this line:>
TRANSACTION = 20, RUN BLOCK = 1024, BUFFER = (1024,1024),
 DBEFILE0 DBEFILE DBEFILE0
WITH PAGES = 50000,
NAME = 'ProdF0',
LOG DBEFILE DBELOG1
WITH PAGES = 50000,
NAME = 'ProdLG';
<snip>

 As the defaults are:
No. of Runtime Control Block Pages:  37
No. of Data Buffer Pages:  100
Data Buffer Pages Memory Resident:  NO
No. of Log Buffer Pages:  24

Which will probably result in :
Error in CATREAD.  Returned status is 42375 (ATCERR 32216)
 at some time in the near future.
