Release 10.1A: OpenEdge Application Server:
Developing WebSpeed Applications

Advantages and drawbacks of state-persistence

State persistent applications are advantageous because they:

Allow a single database transaction to span multiple page requests and to be completely rolled back (undone) in case of error.
Minimize the amount of data that needs to be passed from one request to another.
Minimize database access (re-opening tables) for each request.

However, there may also be considerable overhead associated with state persistent applications because they:

Lock a WebSpeed agent until a transaction terminates.
May tie up one or more database records until the transaction terminates.
