First, you must be on MPE/iX 5.0 or later.
 
Second, you need the version of TurboIMAGE that supports Jumbo
datasets.  Unfortunately, I can't remember the version number, but here's
one way you can determine if you have it.  Do the following, and see if
DBSCHEMA reports an error on the "$CONTROL JUMBO" line:
 
   :run dbschema.pub.sys
   $control jumbo
   :eod
 
If no error from "$CONTROL JUMBO", then you are on the jumbo-capable
IMAGE.  If you got an error like:
   ***** ERROR *****  IMPROPER COMMAND PARAMETER
then you aren't.
 
BTW, ADAGER has the ability to automatically convert a non-jumbo dataset
into a jumbo dataset when you increase the capacity to the point where
the dataset would be larger than 4GB.
 
If you don't have ADAGER, one (slow) way to create a jumbo dataset is
DBUNLOAD, run DBSCHEMA with larger capacity *and* $CONTROL JUMBO, and
DBLOAD.
 
BTW, I'm not familiar enough with the other database tools to know if they
can create jumbo datasets yet.
