* 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
|

* this mode to enable system bootstrapping.
