* particular, access method calls may not occur in this mode since the |
||||
* execution state is outside a transaction. |
||||
* |
||||
* The final two processing modes are used during special times. When the |
||||
* system state indicates bootstrap processing, transactions are all given |
||||
* transaction id "one" and are consequently guarenteed to commit. This mode |
||||
* is used during the initial generation of template databases. |
||||
* |
||||
* Finally, the execution state is in initialization mode until all normal |

* initialization is complete. Some code behaves differently when executed in |
