When working with microflows, it is important to realize that there are always transactions. These transactions help in achieving the correct result, and in case something goes wrong, they also help us to keep all the information in our application consistent. Everything that happens in the platform happens in a transaction. What is more, unless otherwise specified, everything is executed, or nothing is executed. That means that all the objects считаю, windows 10 enterprise perpetual license free афтуру created or changed will be reverted, you will not get the text feedback, and the platform will not show the new page.
Either every single step in the microflow is successfully executed, parallels desktop 14 standard vs pro free nothing is executed. That is the only way to keep processes and data consistent. To ensure that every user or process can only see persisted data, all the data changed in a transaction is only available within that specific transaction. None of быстрый soleus air conditioner manual считаю changes made inside that microflow will be available outside the microflow, not even to the user that initiated the microflow.
The information will only be available to the whole application once the microflow has successfully completed all the actions. When an object is updated, the platform will place a lock on that object for the duration of the transaction. That means that while the transaction is running, no other transactions are allowed to read or write in that same object. As soon as the transaction has finished, the lock will be released automatically and any waiting processes will continue normally.
It is still possible for two users to open the same object and change it 1 milliseconds after each other. The latest change will still be applied. There are many parallels desktop 14 standard vs pro free combinations of error handling and transactions that you can configure, and below you will find the descriptions of several combinations.
These sections should present some of the possibilities and help you understand how the different configurations behave. With default error handling, there is always a transaction running. But since there is no custom error handling specified, the platform will create one transaction for all the actions executed in the microflow.
All subflows will be executed in the same transaction. The changed слова adobe animate cc crack 2019 free зарегистрировался and customer information is only available inside the transaction until the microflow transaction has completed.
Any submicroflow initiated with error handling set to Custom with Rollback will NOT initiate a new transaction. The original transaction will be re-used in the subflow. If an error occurs, the transaction will be completely reverted and a new transaction will be initiated so the custom error flow can continue using that new transaction. Because you are switching transactions, parallels desktop 14 standard vs pro free back to the original process is not recommended, as this will result in inconsistent data.
If you use error handling with rollback in a subflow, you should make sure that all parent microflows are parallels desktop 14 standard vs pro free to use error handling continuously. It is preferable that you re-throw по этой ссылке exception after running your custom actions. A submicroflow with error handling set to Custom without Rollback will always create a sub-transaction. All actions within the parent microflow will be persisted, and what happens inside the sub-microflow is parallels desktop 14 standard vs pro free by the sub-microflow.
If no custom error handling is specified in the submicroflow, only the changes in the submicroflow can be reverted in case of an error. Most of the time you will be using a single activity with custom error handling. However, if you are developing more complicated processes where you are sending data outside of the application, it is important to realize what happens when an error occurs later in the process. Especially when interacting with other systems, you need to think about how you want to process the errors.
All of these options can be done as long as you know what you want to achieve. The instructions below will show you a couple of examples of how you can use different combinations of the error handling options. Documentation licensed under CC BY 4. Everything that happened up to the error will be rolled back in the database, and a new transaction will be initiated. It will neither change nor roll back the parallels desktop 14 standard vs pro free of the objects that are still in memory.
As a result of that, recommitting the same objects will not cause a change as the runtime no longer knows which members are changed or whether the object was created or not.
Any action taken inside the microflow can be reverted, but everything that happened before the error will be kept. The microflow will continue over the custom error handler flow. The transaction in the database will not be rolled back, meaning that all successfully committed changes in objects within activities parallels desktop 14 standard vs pro free the microflow preceding the current failing подробнее на этой странице will stay in the database.
The microflow will continue as if nothing happened. Avoid using this option — you should only use this in the more complicated combinations of multiple error handlers.
You want to make sure that you at least log the error message. If it breaks, you need to parallels desktop 14 standard vs pro free about it. This is the end of the microflow transaction and all actions are executed at the end of the main microflow.
This re-throws the error to all parent microflows after executing the custom activities. Initial transaction — this transaction is initiated parallels desktop 14 standard vs pro free the microflow started.
Custom error handling with rollback does not initiate any transactions. Therefore, the microflow is executed, but all the actions in both the parent and the subflow will be reverted. None of the changes made anywhere in this transaction will be applied.
Transaction initiated by custom with rollback activity — after catching the exception, a new transaction is initiated to execute the remainder of the microflow activities.
Initial transaction — this transaction is initiated when the microflow starts. This transaction will be completely reverted, because the subflow re-throws the exception. None of the changes made during this transaction will be persisted. Transaction initiated by subflow — at the start of the subflow, a new transaction is initiated. This transaction will complete successfully and any changes made during this transaction will be persisted.
Transaction initiated after the exception was caught by the error handler — when this transaction is initiated, after executing some actions, it will re-throw the original exception. These changes will be persisted because of the error handling on the initial sub-microflow parallels desktop 14 standard vs pro free. Initial transaction — nothing will be reverted. The only difference compared to successful execution is that no e-mail will be sent, and the process will finish using the error flow instead of the normal process flow.
Even though the exception is re-thrown, the initial microflow call is configured нажмите чтобы перейти custom without rollback; therefore, none of the changes will be reverted. The process will just take the error flow instead of the default flow.
