Does anyone know of a way to allow large transactions on the MPE HP3000 system?  I am getting an error message because the transactions I am trying to put to the Turbo Image database must exceed the 4MB limit of the transaction manager (XM article below).

The article mentions using the DBXBegin/DBXEnd.  I would appreciate any help from the HP experts out there.

Large Transactions for IMAGE Users   
 
By B T Vikram Kumar, B S Jyoti, Shobha Pradeep 
Commercial Systems Division
 
Background 
 
Of late many of the users of TurboIMAGE and IMAGE/SQL have the requirement of transaction sizes larger than is currently possible today (4 MB). This is true, especially for users who run applications involving bulk puts/ deletes /updates. The situation becomes more difficult with the limitation of the size of the Transaction Manager (XM) userlog, if the transactions are on the same volume set. This integrated solution involving TurboIMAGE/iX, XM, IMAGE/SQL and ALLBASE/SQL addresses these problems. The following sections discuss these issues, and various options available to the users to overcome these issues, as a result of this solution.
 
Current Limitations 
 
Version C.03.00 of TurboImage introduced the concept of dynamic transaction, meaning the application can rollback a transaction at runtime. Later when the Transaction Manager started handling the dynamic transactions, some customers used to see the stalled transaction message due to the limit on the size of the transaction.

Has anyone ever had this happen during a Cobol run on the HP3000 MPE system.  I am not sure what this error pertains to.  If anyone can help me I would greatly appreciate it.  I am not sure if this is a I/O based error or a MPE O/S based error.  It looks like a File system based error.  

At the time the program was doing a data load to the Turbo Image dataset in our database.  Yet Suprtool reads the dataset fine/.
