|---|---|---|
| Synchronous | Agent threads are only terminated at well-defined locations after a shutdown is in progress, such as before or after query execution and message logging. | |
| Asynchronous | The agent thread initiating the shutdown may actively abort other running agent threads. |
Замечания
An unanticipated shutdown can occur because of a system runtime failure or a user initiated abort request.
The policy should be chosen depending on application state requirements. An asynchronous policy may be more responsive during a shutdown but can require the use of other techniques to return the runtime environment to an expected state. A synchronous policy can help avoid inadvertent interruption of updates to these critical global runtime states when a replication agent is invoked synchronously from an application.
