As the number of users accessing the DBEnvironment increases, you should increase the number of concurrent transactions allowed. The maximum should be set slightly higher than the number of expected users because ALLBASE/SQL may start a second transaction on the user's behalf when executing data definition statements such as CREATE. Set the maximum to twice the number of users if you expect to be doing a lot of data definition.

The minimum number of transactions is 2, and the default value is 50. There is no limit on the number of transactions you can request. You can temporarily override the number of transactions with the START DBE statement. The ALTDBE command in SQLUtil allows you to permanently change the maximum number of transactions.
